Check Valve with Thermal Relief
Brand: Parker HannifinParker’s poppet style check valve with thermal relief allow flows up to 130 lpm (40 gpm) and pressure to 420 bar (6,000 psi), with thermal relieving in the reverse direction to protect the circuit from high hydraulic fluid thermal expansion pressures.
Features- Poppet type for minimal leakage - less than 3 drops/min
- Hardened working parts for maximum durability
- Relief feature to give thermal and shock relief
- Single and dual pilot pistons available to create pilot to open check
- Compact design
- High tolerance for contamination
- All external parts zinc plated
