  • 316L SS metal valve & top options
  • Molded PTFE/EPDM diaphragm
  • They can be adjusted up to 350 psi
  • Four optional pressure ratings (springs)
  • Multiple valve sizes
  • Tamper-resistant adjustment screw
  • High-temperature option up to 300°F

The Features & Benefits of the High-Pressure Relief Valves

  • Tamper-resistant adjustment screw
  • High-temperature option up to 300°F

Back Pressure Valves

Griffco back pressure valves (also called loading valves or anti-siphon valves) help stabilize the downstream pressure and deliver consistent flow. They ensure that certain pumps deliver consistent flows or allow for high accuracy & stable operation. Robust construction ensures reliability in the demanding conditions of municipal & industrial applications.

The High-Flow Back Pressure Valves as well as the G-Series Medium-Flow Back Pressure Valves & the M-Series Low-Flow Back Pressure Valves are made to improve the chemical feed system performance by applying continuous back pressure to the chemical feed pump, while also serving as an anti-siphon valve. The larger orifice size of the High-Flow valves makes them perfect for use with high-viscosity fluids.

Features & Benefits

  • Anti-siphon feature
  • Durable, sturdy, machined construction
  • Flanged, union, threaded, as well as socket connection variants
  • Molded Noryl top w/ integral hardware locking
  • 316L SS metal valve & top options
  • Molded PTFE/EPDM diaphragm
  • The G-Series & M-Series valves can be adjusted up to 350 psi, and the High-Flow valves are adjustable up to 250 psi
  • Four optional pressure ratings (springs)
  • Various sizes
  • Tamper-resistant adjustment screw
  • High-temperature option up to 300°F

The Unibody back pressure valves are state-of-the-art solutions that ensure leak-free connections and operation. Their design offers flexibility in changing connection types, simplifies maintenance, and eliminates the need for additional system components.
