Val-Matic 504A Swing-Flex check valve prevents reverse flow in fluid lines. This Swing-Flex check valve is ideal for various applications, such as fracking, dewatering, wastewater processing, irrigation, mining, pulp & paper and low pressure gas service operations.
During system flow conditions, the fluid movement / pressure forces the disc to open position for allowing 100% (unrestricted) fluid flow. Under reverse flow conditions, the valve disc returns to the closed position for preventing reverse flow completely.
Val-Matic 504A Swing-Flex check valve conforms to AWWA C508 standards and is NSF/ANSI 61 & NSF/ANSI 372 Certified. This Swing-Flex check valve is lead free and is safe for installation in drinking water systems. This check valve is also compliant with ISO 9001 standards.
Val-Matic 504A Swing-Flex check valve can be installed either in vertical or horizontal flow applications. The flow arrow direction must always point towards the direction of fluid flow during normal system operation. Val-Matic check valve features flanged ends and should be mated only with flat faced pipe flanges. The check valve is fastened to the pipe system using flange bolts / studs. The adjacent piping & valve must be aligned & supported for preventing any chances of cantilevered stress on the valve. The tightening of the bolts must be done in gradual steps with crossover tightening method. Full face resilient gaskets should be used for sealing the connection in between the valve & the piping system.
A. Various safety precautions are necessary for ensuring the safe operation of Swing-Flex check valve.
A. A simple device like Val-Matic 504A Swing-Flex check valve is designed for ensuring one way flow of liquid / slurries. It features a disc that rotates / swings on a hinge to open / close, allowing / restricting the fluid flow. This disc closes to prevent any chances of fluid backflow.
A. No, this Swing-Flex check valve is designed to provide at least 5 years of trouble free operation. Apart from the basic unclogging & maintenance routine, this check valve does not require frequent maintenance.
A. The most ideal installation is at the pump. This Swing-Flex check valve may be installed on the pump's suction side for maintaining the pump's prime even after pump shutdown. This check valve prevents backflow from the downstream system when used on the discharge of the pump after the pump shuts off.
A. Yes, Val-Matic 504A Swing-Flex check valve supports installation in both vertical & horizontal directions. This Swing-Flex check valve allows smooth and unrestricted fluid flow in vertical flow applications.
