Doering Normally Open Check Valve 904B9561300SS

Description
The new DRV screw-in, poppet type, direct-acting cartridge-style hydraulic relief valve from Doering is designed for use as a pressure limiting device for common hydraulic circuit protection. The DRV blocks flow from port 1 to port 2 until sufficient pressure is available at port 1 to force the poppet from its seat. The cartridge offers fast response to load changes in typical hydraulic circuits requiring low hysteresis, low pressure rise and low internal leakage.

Key features include:
Hardened poppet and seat for long life and low leakage
Adjustable, fixed or tamper-resistant adjuster available
Compact size for minimal space requirements
Optional spring ranges
Industry standard cavity
Alternate materials available
