Product catalog summary
Specifications
  • Operating Pressure: 350 BAR
  • Flow: 200 L/min
  • Response Time - Typical: 2 ms
  • Internal Leakage: 50 ml/min max at 70 bar
  • Temperature Range: -40°C to +120°C (-40°F to +250°F)
  • Cavity: T-3A
  • Fluids: Mineral-based fluids with viscosities of 7.4 to 420 cSt
Features
  • Main stage orifice is protected by a 150-micron stainless steel screen.
  • Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
  • Will accept maximum pressure at port 2; suitable for use in cross port relief circuits. Consider spool leakage if used in such circuits.
Operation

Fast-acting, pilot-operated, balanced piston relief cartridges are normally closed, pressure-limiting valves used to protect hydraulic components from pressure transients. They open and close quickly, sacrificing smoothness. When the pressure at the inlet (port 1) reaches the valve setting, the valve opens to the tank (port 2), throttling flow to limit pressure rise. These valves have low pressure rise versus flow and respond quickly.

Installation Dimensions

Details on installation dimensions and torque specifications are provided, including maximum torque values for different hex sizes.
