Non Return Valves
BiS Wells offer a range of non-return valves. These simple and reliable valves allow flow only in one direction. If the system pressures mean that flow will occur in the opposite direction the valve will shut off.
These valves use an elastomeric seat and spring for optimum leak tight performance even on high pressure gas. Depending on the pressure and flow will determine which type of non-return valve is most suited to your application.
Our non-return valves can handle pressures up to 6,500 Psi. Valves are offered in Aluminium Alloy as standard but can be manufactured from Stainless Steel, Brass and Aluminium Bronze. Valves range from ¼” ports up to our largest non-return valve at 1.5”.
Our non-return valves are suitable for both pneumatic and hydraulic applications, and as standard valves are offered with Nitrile or Viton seals however please contact us for medium compatibility as other elastomeric materials can be offered.
All our non-return valves can be manufactured specially for Oxygen use, please contact us for more information.
