flow-controlcartridge

Specifications · Operating Pressure:350BAR · Flow:120L/min · Response Time - Typical:25ms · Internal Leakage:50ml/min.max.at operating pressure · Temperature:-30°C to +120°(-22°F to+250°F) · Cavity:T-2A · Fluids:Mineral-based fluids with viscosities of 7.4 to 420 cSt. Features · The main stage orifice is protected by a 150 micron stainless steelscreen. · Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar) · Intended for use on the actuator side of the system as flow through the valve must cease for the valve to reset. If used on the pump side of a system, pump flow must be shut off for the valve to reset. Operation Kick-down sequence Valve will kick completely open and remain open once the pressure at the inlet (port 1) exceeds the valve setting, creating an unrestricted flow path from port 1 to port 2 (sequence). The pressure setting at port 1 is relative to the drain (port 3). The valve remains open as long as the pressure at port 1 exceeds the pressure at port 2. To reset the valve, pressure at port 1 must fall below the setting of the valve, flow from port 1 to port 2 must cease, and pressure at port 2 must be equal to or greater than the pressure at port 1.
