Surgebuster Check Valve: 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.
Swing-Flex Check Valve: Designed to be maintenance free, ValMatic Swing-Flex® Check Valve provides superior performance when compared to traditional swing checks. The Memory-Flex® disc, the valve's only moving part, is easily replaced without removal of the valve from the line. Its unrestricted full flow design makes the Swing-Flex® an excellent choice for slurries and sludge, even in vertical flow up applications. Non-slam performance is assured by placing the valve seat on a 45° angle, thereby minimizing disc travel. When used with optional rubber lining, our Swing-Flex® Check Valves are ideal for highly abrasive and corrosive applications. Independent flow, cycle, and proof of performance test reports are available on request.
Tilted Disc® Check Valve - Provides both low head loss and non-slam performance. Its streamlined body contouring, flow area 40% greater than nominal pipe size, and hydrodynamic disc combine to provide the lowest head loss of any check valve produced today. Non-slam closing is assured by both an angled seat design which minimizes disc travel and an eccentrically mounted disc. Top and/or bottom mounted dash pots may be added for systems with extreme conditions such as excessively high shut-off heads or volatile reverse flows to further assure against valve slamming. The valve's tapered seat and disc, designed with wear resistant materials, assures tight seating and long life even in the most severe applications.

Dual Disc Check Valve: With today’s demanding system requirements, engineers must specify piping components that are both COST EFFICIENT and RELIABLE. The design of the Val-Matic DUAL DISC® Check Valve answers those needs by incorporating many unique characteristics not found in similar check valves. 2” - 12” valves include Ductile Iron construction, with a 250 psi, cold working pressure rating. They are UL/FM approved and available in Wafer (ANSI 125, ISO PN10, ISO PN16) and Grooved End IPS connections. Sizes 14” and larger are available in cast and ductile iron.
Swing Check Valve: The most commonly used check valve in our industry was the Horizontal Swing Check Valve (with or without Lever, spring or cushion).The technology behind this valve is vintage 1920 and probably could be traced back to the Roman aqueducts if one bothered to check. Eighty years of technological advances have brought about the electric light, the automobile, the telephone, the internet, and a superior competitively priced check valve, the Swing Flex. It has superior design features which allow it to outperform conventional swing check valves in all application and is especially preferred for applications such as sewage, sludge, slurries, corrosive or abrasive service.
Oil Cushion Lever and Weight Check Valve: The most commonly used check valve in our industry was the Horizontal Swing Check Valve (with or without Lever, spring or cushion). The technology behind this valve is vintage 1920 and probably could be traced back to the Roman aqueducts if one bothered to check. Eighty years of technological advances have brought about the electric light, the automobile, the telephone, then internet, and a superior competitively priced check valve, the Swing-Flex. It has superior design features which allow it to outperform conventional swing check valves in all applications and is especially preferred for applications such as sewage, sludge, slurries, corrosive or abrasive service.
