Check valves are critical for the prevention of backflow and protection of pumps from cavitation damage. 

Shinwoo Valve's patented TOV-A is a check valve capable of blocking reverse surge and preventing cavitation via shut-off in case of sudden pump stoppages, as well as relieving the pump's vacuum and regulating flow rate.  

Because TOV-A has the functionalities of three valves built into one, assembly, disassembly, and maintenance are made much easier with significantly reduced installation footprint and overhead.

Features

•Three different products in one : Non-slam check, shut-off, and balancing function in one valve

• Reduction of required parts : No reducer or elbow pipe necessary

• Two different sizes for suction side and exit side are available

• Convenient repair : Repair can be performed on site without removing the valve from the line

• Streamlined flow passage and low head loss for enhanced pump efficiency

• Field-proven to prevent water hammer damage

• Opening can be adjusted manually to control fluid flow
