Pressure reducing/relieving valve from Sun Hydraulics

Description

This electro-proportional, direct-acting reducer/reliever valve reduces a high primary pressure at the inlet port (Port 2) to a constant reduced pressure at Port 1, with a relief function from Port 1 to tank (Port 3). The valve is biased to the relieving mode. Energizing the coil connects Port 2 to Port 1. Increasing the current to the coil will proportionally increase the reduced pressure at Port 1. If pressure at Port 1 exceeds the setting induced by the coil, pressure at port 1 is relieved to port 3. This valve is closed in the transition between reducing and relieving resulting in very low consumption of oil.

  • The solenoid tube assembly is fatigue rated for 3000 psi (210 bar) service.
  • Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio.
  • This valve features a filter installed on port 2 with a micron rating of 280.
  • Specified leakage is out of port 3, with 3000 psi (210 bar) at port 2 and port 1 deadheaded.
  • For best performance, an amplifier with current sensing and adjustable dither should be used. Recommended dither is 200 Hz.
  • This valve is available with a push-type manual override. There is no upper limit to the pressure setting when using the M control. The more force you exert on the manual override, the higher the resulting pressure. This option is also rated for 3000 psi (210 bar).
  • The cartridge installation torque of 22 lbf ft (30 Nm) should be respected for best performance.
  • Full reverse flow from reduced pressure (port 1) to inlet (port 2) may cause the spool to close. If reverse free flow is required in the circuit, consider adding a separate check valve to the circuit.
  • The metal coil nut is a functional feature of the valve and should be correctly installed for proper performance of the valve.
  • Coil connector options offer ratings up to IP67. See individual coil product pages for details.
  • Coils can be mounted on the tube in either direction.
