Sun Hydraulics Sequence Valve with Reverse Flow Check - Direct-acting - SCCALAN

Features
 • Direct-acting sequence valves 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 valves 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)
 • All 3 port sequence cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size)
 • Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids
 • Exposure to petroleum based fluids, greases and lubricants will damage the seals
 • 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)
 • Suitable for use in load holding applications
 • Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP for external stainless steel components, or /LH for external zinc-nickel plated components
 • See the CONFIGURATION section for all options
 • For further details, please see the Materials of Construction page located under TECH RESOURCES
 • Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations
