1 FLOW CONTROL VLVES Flow Control Valves The HYDC family of flow control valves permit safe, simple and repeatable control of hydraulic fluids at operating pressures to psi. The standard slotted control spindle allows for a wide range of infinitely variable flow adjustments with excellent flow characteristics. Precise adjustment of flow is achieved by a micrometer style adjustment knob featuring a color coded flow indicator for accurate, easy-to-read visual flow reference. Design modifications and special materials are available for corrosive fluids such as phosphate ester, acids and caustics. PN# /.7 / CC-7 -

2 FLOW CONTROL VLVES Flow Control Valve Design Features and Options Color Coded Flow Indicator Safety Screw and Spindle Knob Locking Set Screw Threaded Spindle Housing for Panel Mounting Kit Slotted Spindle Guided Poppet NPT, SE or SPP Ports Introduction Our complete line of flow control valves are designed and manufactured by our ISO 9 certified FLUTEC Division. Description The HYDC family of flow control valves permit safe, simple and repeatable control of hydraulic fluids at operating pressures to psi. The standard slotted control spindle allows for a wide range of infinitely variable flow adjustments with excellent flow characteristics. Precise adjustment of flow is achieved by a micrometer style adjustment knob featuring a color coded flow indicator for accurate, easy-to-read visual flow reference. Design modifications and special materials are available for corrosive fluids such as phosphate ester, acids and caustics. Valve Design HYDC flow control valves can be adjusted easily and precisely by means of the control knob. Increasing the number of turns from the fully closed position provides a steady increase of the flow rate. The colored scale permits accurate repetition of settings and the colored triangle on the rising spindle provides a visual indication of the increasing cross section of the flow area. set screw on the side locks the knob at the desired setting. HYDC flow control valves include a unique safety spindle design feature. s the valve spindle is turned counter-clockwise, the spindle shoulder will engage the safety screw limiting the travel of the spindle. The hardened, high-strength steel safety screw is sealed in position to discourage tampering. - Product Features Size and under, zinc plated body, size and up, phosphated body FPM (Fluoroelastomer) seals Slotted control spindle for precise and linear flow adjustments Exclusive safety spindle design Color coded spindle for accurate flow control Guided poppets for smoother, chatter free operation vailable Options Panel mounting kit (available for size - only) and psi cracking pressure springs (7 psi standard) PN# /.7 / CC-7

HYDC Hose reak Valves eliminate uncontrolled movements of the actuator in case of line rupture. They are commonly applied with dead weight cylinders. These valves are volume limiting flat seat valves. t normal flow, the poppet is held open by a spring with enough force to counteract the force on the poppet created by the flow. When the supply line is ruptured, the flow from to exceeds the specified flow rate, the P across the poppet creates a force greater than the spring force and closes the valve. This closing flow rate is adjustable. The valve opens automatically by pressurizing connection. Depending on the pressure P, the leakage rate through the valve is approximately to in / min. If this is excessive, the valve s can be sealed and made leak-free. The valves are installed between actuators and possible line breakage points. cartridge-type valve can be installed into an actuator port. housing-type valve can be installed close to the actuator or even directly into the actuator itself.

SE /-.9 RCC lbs. / NPTF.7 Recommendations Hose break valves, type RE must only be used to safeguard users in the event of hose breaks. They must not be used as switching valves for repeated closing actions. If closing actions occur during normal operation, the setting of the hose break valve is not suitable for the operating parameters of the system. The hose break valve must be replaced by a new one with a modified setting. In order to prevent hose break valves reacting to flow rate fluctuations inherent in the system, e.g. due to switching of directional valves, the actuating flow rate should be at least % above the normal maximum system flow rate. If high viscosity fluctuations occur, the valves must be set to a higher actuating flow rate to ensure trouble-free operation at high viscosity. However, the valves must still react at a low viscosity. Since this range depends largely on the system, whose operational flow rate fluctuations can also depend on viscosity, the appropriate setting for the valve is best determined on site. Sizing Hose reak Valves In order for a hose break valve to work properly there must be a difference between the normal operating flow rate (from pump) and the emergency flow rate created by a hose or line break. The emergency flow rate must be significantly higher than the normal operating flow. Why? The hose break valve is designed to only be closed in an emergency situation. These valves should not be cycled (opened and closed) with the system. Cycling the valve and/or excessive vibrations will lead to premature failure of the valve components. How do you determine the emergency flow rate? You must perform a test with the actual system in a hose break simulation. This test should be run with the minimum load on the cylinder/lift to determine the minimum emergency flow rate for the system. To test, break the line open or open a directional valve and allow gravity to pull down the cylinder/lift. The flow rate measured during this test is the emergency flow rate. The hose break closing flow rate setting is adjustable and should be set to close at a flow rate between the normal flow rate and the emergency flow rate. The closing flow rate should be set at least % higher than the normal flow rate, and should be set at least % below the emergency flow rate. How do you set the closing flow rate for the valve? The gap between the poppet and the valve body is adjustable by means of the lock nut and adjustment nut on the end of the poppet. The larger the gap, the higher the closing flow rate for the valve.

FLOW CONTROL VLVES EV Series utomatic ir Vent Valves Description The HYDC ir Vent Valve eliminates air bubbles which accumulate in hydraulic systems immediately after start-up or after long periods

20 FLOW CONTROL VLVES EV Series utomatic ir Vent Valves Description The HYDC ir Vent Valve eliminates air bubbles which accumulate in hydraulic systems immediately after start-up or after long periods of shut-down of the system. The ir Vent Valve remains open until the valve reaches a psi differential pressure. Pressure must be maintained above psi to keep valve closed. This type of operation of the HYDC ir Vent Valve allows for easy start-up of hydraulic systems. Due to the compact design the ir Vent Valve requires minimum space. Model Code EV - / Part Number Technical Data Operating Pressure Range P min psi ( bar) P max 7 psi ( bar) Material Carbon Steel Operating Flow Range Q min. gpm ( l/min) Q max gpm (7 l/min) to achieve higher flow rates, parallel connection is possible Mounting The inlet port is connected to the pressure line and the outlet port should be connected back into the non-pressurized reservoir.
