Pilot-operated, balanced-piston relief cartridges are normally closed pressure regulating valves. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to regulate the pressure.
These valves are accurate, have low pressure rise vs. flow, they are smooth and quiet, and are moderately fast. All 2-port relief cartridges (except pilot reliefs) are physically and functionally interchangeable (same flow path, same cavity for a given frame size).
- Will accept maximum pressure at port 2; suitable for use in cross port relief circuits
- Main stage orifice is protected by a 150-micron stainless steel screen
- Not suitable for use in load holding applications due to spool leakage
- Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids
- Incorporates the Sun floating style construction to minimize internal parts binding
