RELIEF VALVE PILOT OPERATED U.S. PATENT 6,805,155 and 7,069,945

Overview

Description

The RV10-28X is a screw-in, cartridge style, pilot operated, relief valve with reverse free flow check valve, intended for use as a pressure limiting device in demanding hydraulic circuits which require fast response, low hysteresis, low leakage, low pressure override and reverse free flow features. The RV10-28X blocks flow from port 1 to port 2 until sufficient pressure is present at port 1. Relief flow path from port 1 to port 2. Reverse flow from port 2 to port 1 occurs when pressure at port 2 is higher than pressure at port 1.

Features

  • Variety of adjustment options; adjustments cannot be backed out of the valve.
  • Can be operated in relief valve mode or check valve mode.
  • Several pressure ranges available.
  • Hardened spool and cage for long life.
  • Fast response.
  • Industry-common size.
