Back Pressure Valves

Back-Pressure Valves

Pumps play an integral role in many manufacturing processes. Industries such as water treatment, pharmaceuticals, food and beverage, and others rely on them. Pumps help to move liquids and distribute fluids properly and consistently. However, anytime fluids, including chemicals are in a process, pressure issues can arise. Problems with pressures can damage machinery, hinder production efficiency, and even pose dangers. A Griffco back pressure valve can solve these challenges.

A Look at How a Chemical Back Pressure Valve Works

These valves ensure that metering pumps and similar devices produce a consistent flow. The valves improve the accuracy and effectiveness of pump processes. The valves keep pressures at the proper levels and help to prevent interruptions to flow.

Materials Available for the Valves

Back pressure valves suppliers provide these devices in a wide range of materials. Each is of high quality and can last through numerous uses over time. Typical materials include the following:

  • PTFE
  • Alloy 20
  • PVDF
  • CPVC
  • Polypropylene
  • PVC
  • 316L SS

Also, the diaphragm portion of the pressure valve comes in EPDM/PTFE. Other available materials for the diaphragm are FKM, CSM, and PTFE/FKM.

Connections and Spring Ranges

A Griffco back pressure valve has four standard connections. These are flanged, union, socket, and threaded. The spring ranges can vary considerably. For one to 10 bar, the range is 10 psi to 150 psi. For 0.0 to 3.5 bar, the range is 0 psi to 50 psi. 3.5 to 25 bar have a range of 50 psi to 350 psi. Also, the valves are available in 180-degree or 90-degree configurations. Wall mount valves are common as well.

Stabilize the Downstream Pressure

Any production environment needs reliable components to deliver a successful result. For pressure regulation, a chemical back pressure valve is critical. Call Vissers Sales Corp. today so you can purchase and use the valves for your processes.
