Transcription

1 Control Reliable Double Valves Safety Exhaust (Dump) DM Series D Self Monitored - Clutch/rake Control asic Size,,, and 0 Dynamic Monitoring With Complete Memory: Memory, monitoring, and air flow control functions are simply integrated into two identical valve elements. Valves lock-out due to asynchronous movement of valve elements during actuation or de-actuation, resulting in a residual outlet pressure of less than % of supply. Overt action is required for reset cannot be reset by removing and re-applying supply pressure. can only be accomplished by remote air signal, optional electrical solenoid reset signal, or optional manual reset. asic / Normally Closed Valve Function: Dirt tolerant, wear compensating poppet design for quick response and high flow capacity. PTFE back-up rings on pistons to enhance valve endurance operates with or without inline lubrication. Status Indicator (Optional): Includes a pressure switch with both normally open and normally closed contacts to provide status feedback to the press control system indicating whether the valve is in the lockout or ready-torun condition. The Status Indicator can be ordered installed or purchased separately and added to any DM base. Silencers: ll models include high flow, clog resistant silencers. Mounting: ase mounted with SPP or NPT pipe threads. Inlet and outlet ports on both sides provide for flexible piping (plugs for unused ports included). Captive valve-to-base mounting screws. asic Size and 0 Intermediate Pilots: Increases pilot air flow for fast valve response, making it possible to use the same size solenoids as valve sizes, &, thereby reducing electrical power requirements for these larger valves.

3 Control Reliable Double Valves Valve Operation DM Series D Valve de-actuated (ready-to-run): The flow of inlet air pressure into the crossover passages is restricted by the size of the passage between the stem and the valve body opening. Flow is sufficient to quickly pressurize pilot supply/timing chambers and. The inlet poppets prevent air flow from crossover passages into the outlet chamber. ir pressure acting on the inlet poppets and return pistons securely hold the valve elements in the closed position. (ir passages shown out of position and reset adapter omitted for clarity. Valve actuated: Energizing the pilot valves simultaneously applies pressure to both pistons, forcing the internal parts to move to their actuated (open) position, where inlet air flow to crossover passages is fully open, inlet poppets are fully open and exhaust poppets are fully closed. The outlet is then quickly pressurized, and pressure in the inlet, crossovers, outlet, and timing chambers are quickly equalized. De-energizing the pilots quickly causes the valve elements to return to the ready-to-run position. Valve locked-out: Whenever the valve elements operate in a sufficiently asynchronous manner, either on actuation or de-actuation, the valve will move to a locked-out position. In the locked-out position, one crossover and its related timing chamber will be exhausted, and the other crossover and its related timing chamber will be fully pressurized. The valve element (side ) that is partially actuated has pilot air available to fully actuate it, but no air pressure on the return piston to fully de-actuate the valve element. ir pressure in the crossover acts on the differential of side stem diameters creating a latching force. Side is in a fully closed position, and has no pilot air available to actuate, but has full pressure on the inlet poppet and return piston to hold the element in the fully closed position. Inlet air flow on side into its crossover is restricted, and flows through the open inlet poppet on side, through the outlet into the exhaust port, and from the exhaust port to atmosphere. Residual pressure in the outlet is less than % of inlet pressure. The return springs are limited in travel, and can only return the valve elements to the intermediate (locked-out) position. Sufficient air pressure acting on the return pistons is needed to return the valve elements to a fully closed position. ting the valve: The valve will remain in the locked-out position, even if the inlet air supply is removed and re-applied. remote reset signal (air or electric), or a manual push button actuation must be applied to reset the valve. is accomplished by momentarily pressurizing the reset port. ctuation of the reset piston physically pushes the main valve elements to their closed position. Inlet air fully pressurizes the crossovers and holds the inlet poppets on seat. ctuation of the reset piston opens the reset poppet, thereby, immediately exhausting pilot supply air, thus, preventing valve operation during reset. ( adapter added to illustration.) De-actuation of reset pistons causes the reset poppets to close and pilot supply to fully pressurize. air pressure can be applied by a remote / normally closed valve, or from an optional / normally closed solenoid, or a manual push button mounted on the reset adapter. Status Indicator Pressure Switch Pilot booster on Size & 0 only Status Indicator: The status indicator pressure switch will actuate when the main valve is operating normally, and will de-actuate when the main valve is in the locked-out position or inlet pressure is removed. This device is not part of the valve lockout function, but, rather, only reports the status of the main valve. Status indicator (optional) in normal ready-to-run position. asic Size and 0 valves require relatively large pilots to actuate and de-actuate the main valve elements. In order to achieve extremely quick valve response for such large pilots, a -stage solenoid pilot system is incorporated into the design. This keeps the required electrical current to operate the pilots to a minimum. Port Optional Valve asic Size & 0 pilots Schematic - Valve de-actuated Rev. 0/0/7

The fill times were measured while raising (filling) the pressure in a volume from 0 to 0, 60, & 0 psi (0 to.,., &. bar) with a 90 psi (6. bar) inlet pressure. Conversely, the exhaust times were measured while lowering the pressure (exhausting) in a volume from 90 psi (6. bar) down to 90 to 60, 0, & 9 psi (.,., & 0.6 bar).
