.jpg) | Series SCV Spring Check Valve PVC or CPVC, True Union, Compact Design Series SCV Spring Check Valves provide an exact and reliable control of fluids. The SCV Spring Check Valves prevent reversal of flow in piping systems. They 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 plastic cone off the elastomer seat, opening the valve. When the inlet flow stops, a spring moves the cone back onto the seat, stopping the flow. The spring is constructed from 316 stainless steel. All valves feature a true union design that allows for easy removal from a piping system without breaking down piping connections. Just unscrew the two assembly nuts and lift the valve body out of the line. Series SCV Spring Check Valves are the valves of choice for cost sensitive applications that require a full-featured, no compromise value.

.jpg) | Series FPV Flap Check Valve Wafer Style 4" to 8", PVC Construction Series FPV Flap Check Valves prevent reversal of flow in piping systems. They are ideal where back flow 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 flap off the elastomer seat, opening the valve. When the inlet flow stops, back pressure moves the flap back onto the seat, stopping the flow. These flap check valves have been designed to provide excellent flow characteristics. Because of their straight-through flow design they have a lower pressure drop than other check valve designs, and their compact size takes up less space in the pipeline than other types of check valves. Because of their all plastic construction, these valves will never jam or stick as a result of rust or corrosion. Additionally, they will not contaminate sensitive fluids that come into contact with them. Series FPV Flap Check Valves are the valves of choice for cost sensitive applications that require a full featured, no compromise valve. These flap check valves are supplied with o-rings set into the body faces. In most cases, flange gaskets are not required. Valves up to 8" usually require a spacer and should always be used with the same material as the valve. Spacers allow full disc opening with minimum interference. Spacers are not required for DIN and PVDF pipe. Additional Info: http://www.dwyer-inst.com/Product/Valves/Valves/Check/SeriesFPV | ||||||||
.jpg) | Series BCV True Union Ball Check Valve PVC or CPVC Construction, Economical The Series BCV True Union Ball Check Valves are economical, thermoplastic ball check valves ideal for chemical and wastewater applications. The true union design allows for easy removal from a piping system without breaking down any piping connections. The valve body can be lifted out of the line by unscrewing two assembly nuts. Series BCV check valves are applied where back flow could potentially cause damage to pumps, filters, or process equipment. 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 plastic construction gives this series of check valves superior corrosion resistance and they will not contaminate sensitive fluids that come into contact with them. BCV check valves can be easily installed horizontally or vertically. Additional Info: http://www.dwyer-inst.com/Product/Valves/Valves/Check/SeriesBCV | ||||||||
