Valve Actuator Selection V-3000 Series Pneumatic Actuators Two models of V-3000 Series Pneumatic Actuators are available. The exposed model (V-3000-1) is designed for installation in a protected location. The enclosed model (V-3000-2) is available separately and is designed for installation in a location where the actuator might be subjected to tampering. See Table 1 for actuator sizing selection. A V-9502 Series Valve Positioner can be ordered separately for use on the exposed model in applications where sequential operation is desired or additional positioning power is necessary. The V-9502 Pneumatic Valve Actuator Positioner is a precision relay device designed to operate a valve actuator in applications requiring stable, accurate control. The positioner provides maximum positioning power to resist external forces, which might otherwise overcome the actuator. Refer to Table 6 for ordering information. Both models of the V-3000 have a molded synthetic elastomer diaphragm design. This molded diaphragm provides a constant effective area throughout the valve stem stroke. All parts are protected by a sturdy die cast aluminum housing. The actuator assembly can be removed or repositioned by loosening a single set screw without disturbing the rest of the valve assembly. VA-8050, VA-8051, and VA-8052 Series Electric Actuators The VA-8050-1, VA-8051-1, and VA-8052-1 Series Electric Actuators are synchronous motor-driven, non-spring return actuators that feature a force sensing mechanism that assures a constant 50 pound seating force. The VA-8050-1 accepts floating control and requires a 3-wire, 24 VAC control signal from a controller. The VA-8051-1 accepts floating/incremental or proportional control with either a 3-wire, 24 VAC control signal or a +/- VDC signal from a DSC-8500. For DSC-8500 applications, a VA-8000-104 Auxiliary Interface Board (ordered separately, see Table 6) is required. The VA-8051-1 includes a 3400 ohm position feedback potentiometer for remote position indication to meters or as a position feedback to a DSC-8500. The VA-8052-1 provides proportional control and requires a 2-wire, 0 to 10 VDC control signal and 24 VAC power. Valve Body Types for Electric Actuators For floating/incremental signal non-spring return, actuators VA-8050 and VA-8051, the push down to close (VB-3766-1) body type meets the needs of any HVAC application. Because of this, push down to open (V-3966-1) type is not available with these actuators. For the VA-8052 proportional actuator, a push down to open body type is available to suit heating only control applications. M100 Electric Actuators M100 Series Electric Actuators are rotary actuators which, coupled with a Y20EBD-X linkage kit can be mounted on a flare valve. The actuator can be adjusted for the desired closeoff pressure on the valve (see Table 3). Valve Product Information Flare Valves 1/2 Inch 2-Way and 3-Way 5

Table 3: M100 Electric Actuator Models Actuator Type Linkage Valve M120 Non Spring Return Y20EBD-1 M110 Spring Return Y20EBD-5 VB-3XXX- VB-3XXX- VA-8050 VA-8051 VA-8052 Non Spring Return Non Spring Return Non Spring Return Required Required Required M130 Spring Return Y20EBD-1 VB-3XXX- VB-3XXX- VB-3XXX- VB-3XXX- Refer to separate M100 Product Bulletin for complete options available. The M120 is a non-spring return actuator which will hold its position when de-energized. The M110 and M130 are spring return actuators which will return the valve to its normal operating position when de-energized. The actuator can be mounted for stem up or stem down operation, push down to close, push down to open, pull up to close, or pull up to open. On 3-way valves, the seating force can be applied on both the up and the down stroke. Through selection of plug-in electronic boards, the M100 Series actuator is compatible with all Johnson Controls controllers and can provide proportional action on-off (floating), potentiometer, and Metasys as well as control by direct digital input from C500 or Metasys Zone Bus controllers. The M100 Series actuator requires 25 VA from a 24 VAC, 50/60 Hz power supply. Factory assembly of M100 Series actuators to flare valves is available using Q99 ordering codes as follows: Table 4: Q99 Ordering Codes Code Valve Body Example Valve Type Example of factory ordering procedure (order must be given in this sequence for factory to assemble it): Table 5: Factory Ordering Procedure Item Description Code Number 1 Valve Body VB-3766-1 2 M100 Actuator M110AAB-1 3 Linkage Y20EBD-5 4 Assembly Code Q99ADN-1 Table 6: Accessories (Order Separately) Description Enclosed V-3000 Actuator for Field Mounting Valve Position Indicator for V-3000-1 Exposed Style Pneumatically Actuated Valves Valve Position Indicator for Electrically Actuated Valves with VA-805X Actuators only Auxiliary Interface Board for Use with Electrically Actuated Valves Used in Conjunction with a DSC-8500 Valve Positioner for Field Mounting to a V-3000-1 Exposed Style Pneumatically Actuated Valve Valve Positioner Spring for V-3000-1 Exposed Style Pneumatically Actuated Valves Using a V-9502-15 Positioner Span 3.0 psi (21 kpa) 4.3 psi (30 kpa) 8.0 psi (56 kpa) Code Number V-3000-2 V-3000-10 VA-8000-102 VA-8000-104 V-9502-15 V-9502-20 V-9502-101 V-9502-19 Q99ADN-1 VB-3766 2-Way Valves, Stem Down Q99ADN-3 VB-4332 3-Way Valves, Stem Down Q99AUP-1 VB-3766 2-Way Valves, Stem Up Q99AUP-3 VB-4332 3-Way Valves, Stem Up Any valve body listed in Table 2 can be selected. 6 Valve Product Information Flare Valves 1/2 Inch 2-Way and 3-Way

O peration V-3000-1 or -2 Air pressure from a pneumatic controller is applied to the diaphragm of the actuator, which moves the piston against the forces of the internal spring and the fluids. The piston will move the valve plugs to a position where the diaphragm pressure and the spring force balance against the fluid forces. These fluid forces will cause the operating range to shift from the nominal spring range. Reducing the air pressure to the diaphragm of the actuator allows the spring to return the valve plug to its normal position. VA-8050-1 and VA-8051-1 Actuated Valves The VA-8050-1 and VA-8051-1 actuated valves operate on a 24 VAC control signal from a compatible controller. Recommended system controllers for the VA-8050-1 include Metasys, the DSC-8500, and the C210 Digital Controller. Recommended system controllers for the VA-8051-1 include the DSC-8500 and the C210 Digital Controller. The controller sends a 24 VAC signal to the up or down terminal on the circuit board depending on the desired movement of the valve. This signal causes the motor to rotate in the proper direction and, through the lead screw and lever, move the valve stem and plug assembly up or down. When the controller stops sending a signal, the valve stem and plug assembly remains in place. When the controller closes the valve, a shutoff force will build up. When this force reaches 50 pounds, the lever activates a force sensor which stops the motor. Field calibration of the force sensor is not required. The actuator maintains the shutoff force even if power to the controller is lost. When the controller signals the valve to move in the opposite direction, the shutoff force will be reduced and the valve will modulate. On VA-8051-1 actuated valves, an internal position feedback potentiometer is connected to the R, W, and S terminals. Specifically, the wiper is connected to W. The wiper will be at the R end when the actuator is retracted and at the S end when the actuator is fully stroked. VA-8052-1 Actuated Valves The VA-8052-1 actuated valve operates on 24 VAC power and a 0 to 10 VDC control signal from a compatible controller. Recommended system controllers include the Metasys C210 Digital Controller and the DSC-8500. The controller sends a voltage signal (typically 0 to 10 VDC) to the COM (common) and IN (input) terminals on the actuator circuit board, depending on the desired position of the valve. This signal is compared to the actual valve position via the integral feedback potentiometer. The internal circuit then causes the motor to rotate in the proper direction and, via the lead screw and lever, move the valve stem and plug assembly to the position called for by the input signal. When the controller closes the valve, a shutoff force builds up. When this force reaches 50 pounds, the lever activates a force sensor, which stops the motor. Field calibration of the force sensor is not required. The actuator maintains the shutoff force even if power to the controller is lost. When the controller signals the valve to move in the opposite direction, the shutoff force is reduced and the valve modulates. M100 Series Actuated Valves The M100 Series actuated valve operates on 24 volts AC and is available with On-Off/floating control action or proportional control action. The actuator is spring return to normal position on loss of power. The M100 Series is Metasys compatible and will work with any Johnson Controls controller. The controller sends a signal to the actuator dependent on the desired movement of the valve. This signal causes the motor to rotate in the proper direction and, through the rack and pinion, drive the valve stem and plug assembly up or down. When the controller stops sending a signal, the valve stem and plug assembly remains in place. When the controller closes the valve, it applies the set spring load to the valve stem at the actuator s end of travel. On 3-way valves, the preset spring load is applied at both ends of travel. On loss of power, the actuator will return to its normal position and apply the set load to the valve stem in that position. Valve Product Information Flare Valves 1/2 Inch 2-Way and 3-Way 7

I nstallation It is recommended that these valves be mounted in an upright position in a conveniently accessible location. Sufficient clearance must be allowed for actuator and trim removal. These valves must be piped with the flow in the direction indicated by the arrow so that the plug seats against the flow. On electrically actuated valve assemblies, all wiring must be in accordance with applicable electrical code requirements. Input lines to the actuator must be wired correctly for the valve to move in the proper direction. When used with V-3000 pneumatic actuators, field adjustments for accurate sequencing with other valves can be made to "fine tune" the actuator. Turning the actuator lower spring seat will compress or extend the spring to change the setting of the valve. Turning the lower spring seat counterclockwise (looking down on the actuator) will raise the diaphragm pressure required to start to move the valve; clockwise will lower this setting. Table 7 gives the adjustment ratio for V-3000 actuators used on flare valves. Table 7: Spring Adjustment Ratios ➁ Valve Actuator Spring Size, psi Adjustment Ratio ➁ V-3000 3-6 0.53 Flare V-3000 4-8 0.71 V-3000 9-13 0.71 The spring range is specified by the diaphragm pressure at the top of the stroke and the bottom of the stroke. The Adjustment Ratio is given as changes in diaphragm pressure (psig) per turn of the lower spring seat. 8 Valve Product Information Flare Valves 1/2 Inch 2-Way and 3-Way
