VAL-MATIC 504A Swing-Flex Check Valve, Flanged Connection, 250 psi

Val-Matic 504A Swing-Flex check valve is used in combination with metering pumps to control the flow of sludges & slurries, as well as prevent backflow into supply lines. This 4 inch check valve features non clog design, ensuring that the flow area is unrestricted for maximising flow and lowering unwanted headloss. This smooth streamlined contouring & unrestricted flow area allows for the passage of large solids, thereby minimising the chances of valve clogging. Val-Matic Swing-Flex check valve further features fusion bonded epoxy coating on both exterior & interior surfaces for preventing any chances of fluid contamination. Additionally, this coating also minimises wear in abrasive conditions & harsh industrial environments.

This Swing-Flex check valve have a domed access port that allows easy removal of the disc without any need to remove the valve from the fluid line. This feature allows for quick & easy maintenance of the check valve while minimising downtime. Val-Matic 504A Swing-Flex check valve's synthetic reinforced disc have an O-ring type seal that assures positive seating at low and high pressures. Its valve design is free from hinge mechanism that eliminates any chances of solid / stringy material collection inside the valve. User can also choose from various Val-Matic check valves for wet pump applications on Raptor Supplies.

Uses:

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.

Working Mechanism:

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.

Features:

• Non Clog Design: Val-Matic 504A Swing-Flex check valve features non clog design to ensure that the flow area is unrestricted for maximising flow rate and lowering unwanted headloss. This smooth, streamlined contouring & the unrestricted flow area allows for the passage of large solids, thereby minimising the chances of valve clogging and downtime.
• Fusion Bonded Epoxy Coating: Val-Matic check valve features fusion bonded epoxy coating on both exterior & interior surfaces of the valve for preventing any chances of fluid contamination. Additionally, this coating also minimises wear against abrasive conditions & harsh industrial environments.
• Domed Access Port: This Swing-Flex check valve features a domed access port that allows for easy removal of the disc without any need to remove the valve from the fluid line. This feature allows for quick & easy maintenance of the check valve while minimising downtime.
• Drop Tight Seating: Val-Matic 504A Swing-Flex check valve's synthetic reinforced disc features an O-ring type seal which assures positive seating at low and high pressures. Its valve design is free from hinge mechanism that eliminates any chances of solid / stringy material collection inside the valve.

Standards and Approvals:

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.

Installation:

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.

Frequently Asked Questions:

Q. What safety precautions should be followed before using the Swing-Flex check valve?

A. Various safety precautions are necessary for ensuring the safe operation of Swing-Flex check valve.

• This valve should be mated only with flat faced pipe flanges using lubricated flange bolts / studs.
• User should check for any leakages after installing the valve into the fluid line.
• As the Swing-Flex check valve is unidirectional, it should be ensured that the arrow on valve points is in the same direction of fluid flow.
• Provisions should be made and pipe should be properly aligned for minimising stress on the valve.
• Flange bolts must be evenly tightened in a cross rotation pattern to prevent any chances of flange damage.

Q. How does Val-Matic 504A Swing-Flex check valve work?

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.

Q. Do Val-Matic 504A Swing-Flex check valve require frequent maintenance?

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.

Q. Should Val-Matic 504A Swing-Flex check valve be installed before or after the pump?

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.

Q. Can Val-Matic 504A Swing-Flex check valve be vertically installed?

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.
