Stainless steel and PVC ball valves. BSP threaded inlets allow them to be plumbed into your pump or filter application using standard pipe fittings. For other valves such as gate valves, globe valves, 2 pc or 3pc valves and actuated or solenoid valves please inquire. Suitable for use with diesel, biodiesel, unleaded petrol and oils. We often use 1 pc ball valves in pump bypasses or centrifuge bypasses.
