Sequence relief valve MSCCA series

flow-controlcartridge

Specifications · Operating Pressure:350BAR · Flow:60L/min · Internal Leakage:0.7ml/min.max.to 80% of norminal setting · Temperature:-40°C to +120°(-40°F to+250°F) · Cavity: T-11A · Fluids:Mineral-based fluids with viscosities of 7.4 to 420 cSt. Features · Although this is a zero pilot flow valve, port 3 (drain) must be connected to maintain a pressure reference in the control chamber. If port 3 is blocked, reciprocating seal weepage will cause the valve to malfunction · Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar) Operation Direct-acting sequence Valve with reverse-flow check will supply a secondary circuit with flow once the pressure at the inlet (port 1) has exceeded the valve setting. Additionally, these Valve incorporate an integral check valve to provide reverse flow from port 2 (sequence) to port 1 (inlet). The pressure setting of a sequence valve controls the pressure at port 1 relative to the pressure at the drain (port 3).
