Check Valves（Material：Ductile Cast Iron）

Check valves for fluids are a type of valves which allow fluids to flow in one direction, but automatically close when the flow reverses. They are also called non-return valves or one-way valves. They can prevent the backflow securely and open with small differential pressure. They are applied to piping systems where the backflow prevention is required, frequent open/close are expected, some restrictions exist around the pipings, etc. To install, there are screw-in connection type to screw in the check valve, and flangeless type that clamps the entire check valve with pipes. Furthermore, they are divided into small diameter valves or large diameter valves. Materials of the main body are copper alloy, stainless steel, fluoropolymer, plastic, etc. Sealing materials vary depending on the application; metal is used for places where the temperature becomes high due to steam, etc., and rubber is for places under low temperatures such as hot or cold water.

JIS 10K Type - Cast Iron F Type Swing Check Valve (JIS B 2031)

TOYO VALVE

A FC200 main body material cast iron F type swing check valve.

[Features]
· Suppresses water hammer increasing the disc closing speed and improves the sealing performance by setting the counterweight in the Closed moment position.
· The opening and closing of the disc is performed more smoothly and the flow of the low-voltage fluid is accelerated by setting the counterweight in the Open moment position and maintaining the balance with the disc.
· The inner structure of the swing check valve with a counterweight is simpler compared to other shock absorbing reverse valves. Therefore, there are fewer blockages caused by contaminants.
· The swing check valve with a counterweight enables both horizontal and vertical pipe connections.
