Non-Return Valves & Suction Strainers

The Crest range of non-return valves & suction strainers are designed specifically for use with the Crest VSX, VSL, CSS and PPS ranges of vertical pumps that are built for harsh, corrosive and acidic materials.

Machined from solid plastic, they are exceptionally rugged and robust, equally suitable for use on either the suction or discharge side of the pump.

As they are flap valves, the range operate with a minimum of pressure loss. They are available in two versions; NRV as a simple non-return valve or an NRVS which incorporates a suction strainer.
