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.
TF1 Tideflex Check Valve: The Curved Bill Tideflex uses the same construction for the body of the valve as the traditional Tideflex, but has a bill that is thinner and more resilient. The bill is formed to a 180-degree curve that returns to the closed position even more naturally than a straight bill. The curved bill increases the sealing area and allows the valve to form a tighter seal around solids that are typical in storm water, effluent and CSO outfalls. The Curved Bill is now standard on all Tideflex end-of-pipe products.
TF2 Curved Bill Tideflex Check Valve: The Curved Bill Tideflex Check Valve is a revolutionary design for Backflow Prevention. It offers low cracking pressure to eliminate standing water and very low headloss that is not affected by rust, corrosion or lack of lubrication. The valve is slid onto the pipe and held in place with steel or stainless steel band clamps, eliminating flanging costs. Tideflex TF-2 valves are constructed with a curved bill standard.
Series 35/35-1Check Valve: In some applications and installations, a slip-over pipe check valve (TF-1) is not feasible because of an existing flange in the piping system or an existing flange cemented in the outfall piping system vault. In these cases, the Series 35 Check Valve is the solution.
Series 39 Tideflex Check Valve: The Red Valve Series 39 Slurry Check Valve is designed to handle abrasive slurries, sewage, sludge and other difficult services. The valve’s operation is silent and non-slamming. At the heart of the Series 39 Check Valve is a fabric-reinforced elastomer check sleeve that provides thru-flow at minimum pressure drop across the valve at all times. Forward pressure opens the valve automatically; reverse pressure seals the valve. The check sleeve even seals around entrapped solids.
Series 4739 Light Weight, Low Pressure Check Valve: Lightweight, Economical Design, Elastomer Check Valve resist abrasion and provides backflow prevention, no hinges or seats to bind or freeze, a Maintenance free design, can be mounted in any position, Silent, non-slamming - elminates chatter, Body: Spun Aluminum, Backup Rings: Galvanized Steel, Check Sleeve: Pure Gum Rubber, Neoprene, Hypalon, Chlorobutyle, Buna-N, EPDM and Viton.
Series 39F Large Diameter Tideflex Check Valve: The Red Valve Series 39 Slurry Check Valve is designed to handle abrasive slurries, sewage, sludge and other difficult services. The valve's operation is silent and non-slamming. At the heart of the Series 39 Check Valve is a fabric-reinforced elastomer check sleeve that provides thru-flow at minimum pressure drop across the valve at all times. Forward pressure opens the valve automatically; reverse pressure seals the valve. The check sleeve even seals around entrapped solids.
Series 37 Tidelfex Check Valve: Red Valve’s Series 37 Flanged In-Line Check Valve is a simple, reliable, cost-effective solution for backflow prevention. The revolutionary design of the Series 37 is similar to the patented Tideflex® Check Valve. Designed to be installed between two mating flanges, the Series 37 eliminates the need for a valve body.
Series 37G Insertable Tideflex Check Valve: The Series 37G is a specialized adaptation of the Series 37 that replaces the flange connection with a slip-in cuff. This allows the 37G to be directly inserted into a pipe with absolutely no protrusion whatsoever. An expanding clamp holds the valve in place with and interference fit. The Series 37G is especially popular in CSO systems where lines draining from manholes are flush with the floor of the basin and no room exists for a flange.
Series 2633 Miniflex (Small Tideflex) Check Valve: Manufactured on the same principle as Red Valve’s revolutionary all-rubber Tideflex® Check Valve, the Series 2633 is a simple in-line check valve for threaded end pipelines. Simple in design, the Series 2633 consists of a body, two end caps and the working element, an elastomer check sleeve. In the open position, the sleeve creates a wide, free passage proportional to the flow in the pipeline. On flow reversal, the sleeve closes slowly and completely. The silent, non-slamming Series 2633 Check Valve design eliminates water hammer and facilitates low headloss.
Waterflex Check Valve: The Waterflex Check Valve is an entirely new valve design from Red Valve, specifically engineered for potable water applications. The all-new Waterflex provides low headloss characteristics and features high backpressure ratings comparable to other valve styles, such as lever-and-weight or spring-loaded disks. The Waterflex operates solely on line pressure and backpressure to open and close - no outside energy source is required. As line pressure builds, the 100 percent elastomeric disc is folded away from the perforated plate, allowing water to pass. The "memory" of the rubber will cause the disc to return flat, and backpressure will seal it against the plate to prevent backflow. The elastomer Waterflex is more cost-effective than other valve styles. Moving parts, such as hinges and springs, can seize if routing maintenance and lubrication are not performed. The Waterflex has no moving parts that require maintenance or repairs, so operational costs are low and service life is long.

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.
