Triple Duty Check Valve (OS-Y Type)
Model Number: TOV-Y12, 22
A Triple Duty Check Valve TOV is installed at the outlet of a pump and prevents fluid from flowing backward even during sudden pump stoppages. Its backflow check function protects the pump from water hammer damage by blocking reverse surge into the pipe. Flow rate can be adjusted manually using the indicator and handle, and it's also possible to relieve vacuum inside the pump by opening the built-in bypass valve to induce flow. Shinwoo Valve’s innovative Triple Duty Check Valve design encompasses the functions of a manual blocking valve, balancing valve, and check valve into one for maximum efficiency while maintaining a simple design for easy installation. TOV-Y's OS-Y type design makes it especially suitable for fire protection applications.
