Product Details:

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.
