Stop Valves

BiS Wells offer a comprehensive range of stop valves. These valves can be used to isolate parts of pneumatic and hydraulic systems, for block and bleed functions and also to meter flow.

These hand operated stop valves feature non-rising handwheels for compact use, as well as semi and fully balanced spool designs to ensure smooth and easy operation even at high pressure and high flow. Depending on pressure and flow will determine which type of stop valve is most suited to your application.

Our stop 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 stop valve at 2”.

Most of our stop valves are suitable for both pneumatic and hydraulic applications, please see our overview datasheets for suitability. As standard valves are offered with Nitrile or Viton seals as however please contact us for medium compatibility as other elastomeric materials can be offered.

All our stop valves can be manufactured specially for Oxygen use, please contact us for more information.
