SUN HYDRAULICS Kick-down, pilot-operated, balanced piston relief valve (RQIBLAN)

£777.60

Kick-down relief cartridges act similar to a circuit breaker in an electrical system. The valves will kick completely open and remain open once the pressure at the inlet (port 1) exceeds the valve settting, creating an unrestricted flow path from port 1 to tank (port 2). The valve remains open as long as the pressure at port 1 exceeds the pressure at port 2. To reset 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.

All 2-port relief cartridges (except pilot reliefs) are physically and functionally interchangeable (same flow path, same cavity for a given frame size).
To reset valve, flow through the cartridge must cease.
Main stage orifice is protected by a 150-micron stainless steel screen.
Not suitable for use in load holding applications.
