Grooved End Swing Check Valve with UL,FM

https://korean-machinery.com///inquiryModel SCV, RCV grooved end swing check valves are compact and rugged swing-type units that allow water to flow in one direction and prevent flow in the opposite direction. This valve can be installed horizontally or vertically with the flow in the upward direction as well.
When the pressure at the 1st entrance is higher than the restitution force of a spring connected to a crapper, the crapper is pushed up away from the disc and then fluid flows through the gap between the disc and the crapper.
When the pressure at the 1st entrance is lower than the restitution force of a spring connected to the crapper, the spring’s restitution force makes the crapper press the disc, blocking the flow of fluid.
The valve’s body and pipeline can be connected using grooved couplings. It can be installed either horizontally or vertically depending on the flowing direction of fluid. Designed to minimize water hammer noises (sound caused when a fluid in motion is forced to stop or change direction suddenly) that may be generated when fluid flows backward. Functionally scalable design is adopted with a tapping boss installed on the body (a pressure gauge or connectors can be added).

Wafer Style Butterfly Valve with UL, FM

https://korean-machinery.com///inquiryBy coating the disc with EPDM rubber (elastic body), the restitutive power of this wafer style butterfly valve (HPBO-W1) between the valve’s body and rubber helps to maintain air tightness. A disc rotates 90 degrees to control the fluid in motion, maintaining high responsiveness under operations with low friction loss and low torque.
Fast operation is possible thanks to simplified opening/closing processes. This valve is applicable to control of low/high-pressure water. It is mostly used for firefighting pipelines and industrial water lines.
It is designed for use in fire protection systems where a visual indication is required as to whether the valve is open or closed. They are used, for example, as system, sectional and pump water control valves, and are suitable for installation between ANSI Class 125/150 flanges as well as PN10/16 flanges without the need for flange gaskets. The supervisory switches transfer their electrical contacts when there is movement from the normally open or normally closed disc position during the first two turns of the handwheel.

The Fire protection valves of Sam Chang Foundry Company obtained UL and FM certifications back in 1987, for the first time in Asia. Since then, additionally the company has acquired a range of certifications such as ULC, CE, VDS, GOST, EAC, and CCCF.
The company is building a systematically vertical production system from casting, to machining, assembling to inspection for butterfly valves and check valves etc. It is exporting to 20 plus countries around the world under long-term supply contracts with multinational corporations.
