The new series BCV plastic ball check valves are economical, thermoplastic ball check valves ideal for chemical and wastewater applications.
The valves prevent reversal of flow in piping systems and are ideal where backflow could potentially cause damage to pumps, filters, or process equipment.
The valves operate without the need for any adjustments or settings. Line pressure moves the solid plastic ball off the elastomer seat, opening the valve.
When the inlet flow stops, back pressure (3.75 psi minimum) moves the ball back onto the seat, stopping the flow.
All sizes of valves feature a true union design, and because of their all plastic construction, these valves will never jam or stick as a result of rust or corrosion.
Also, they will not contaminate sensitive fluids that come into contact with them. Units come in PVC or CPVC plastic bodies with EPDM or FPM o-rings for a wide range of chemical compatibility and are available in1/2? to 4? sizes.
The new series BCV plastic ball check valves are available from Dwyer Instruments.
