Check Valves

Surgebuster Check Valve

Surgebuster Check Valve (2 -48 ): The Surgebuster Check Valve is a swing check valve that fully meets ANSI/AWWA C508. But here is where the similarities to traditional swing check valves end. Pumping applications with high head, surge tanks, or multiple pumps, have long proved a challenge to system operators trying to minimize line surges resulting from slamming check valves. Only one real cause exists for slamming check valves -- reverse flow. The impact of the reverse flow is direct and proportional, the faster the reverse flow, the more violent the slam. If reverse flow through the check valve is allowed to develop, the reverse flow will slam the disc into the seat and create a loud water hammer or surge. Now system operators have the solution...the SURGEBUSTER ! The newest member of the Swing-Flex® swing check valve family is the Surgebuster Check Valve. For outstanding performance try a surgebuster today.
