Val-Matic’s Swing-Flex® and Surgebuster® Check Valves have a short, 35° stroke which provides fast closure to minimize slamming and slam related surges. The Swing-Flex® Check Valve has a non-clog design with only one moving part. It is constructed of ductile iron with cold working pressures up 250 psi making it ideal for systems where traditional 125 lb. valves were unsuitable and for those where surges may be a concern.The valve design and performance has been verified through an independent 1,000,000 cycle test and fully complies with ANSI/AWWA C508.
The Surgebuster® Check Valve has all the design features of the Swing-Flex® with the added feature of the Disc Accelerator™ to prevent slamming in the most severe applications. The Disc Accelerator™ is a precision formed stainless steel mechanism that closes the valve disc rapidly thus avoiding slamming by flow reversal and yet allowing the disc to be stabilized under flow conditions.The accelerator is fully enclosed within the valve and completely out of the flow path.
