Measures for prolonging the lifespan of swing check valves! LT type swing check valve

Measures for prolonging the lifespan of swing check valves! LT type swing check valve

Recommended for extending the lifespan of check valves installed near pump discharge outlets! This is a wear-resistant swing check valve.

We have heard many cases from customers regarding swing check valves installed near pump discharge outlets that have extremely short lifespans due to wear. In response, our company has independently developed this product, which achieves a longer lifespan through a structure that differs from conventional JIS standard products. If you are experiencing symptoms such as the valve body falling off despite not being used for a long time, or severe wear due to flowing corrosive fluids like seawater, please feel free to consult us.
