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.

Swing-Flex Check Valve (2"-48"): 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.

Dual Disc Check Valve (2"-24"): 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.
Body Alignment Fins - provide precise alignment in ANSI 125 and ISO PN10 and PN16 installations
Threaded Silent Check Valve - Silent Operating, spring return center guided type check valve. Non Shock Closure, Full flow area, Drop Tight Seating, FM Approved, Threaded, Wafer, Flanged Globe and Grooved end styles, 1/2" thru 42" (DN15 -1000mm), Pressure Range 0-720 psi (PN50 bar (50 KG/cm2)
Tilted Disc® Check Valve (4"-60")- 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 by-pass - for backwashing screens and draining
Foot Valve (2"-48"): Design of the Sure Seal Foot Valve evolved through the need for a reliable valve that could provide positive seating action at both low and high quality pressures without slamming. The Val-Matic® Sure Seal Foot Valve satisfies these requirements plus offers low headless through the full-ported area and heavy-duty stainless steel basket screening.
