JIS MARINE VALVE

Introduction:

The valve disc moves up and down in the valve body. When the medium flows back, the valve is automatically closed by the medium pressure. Some valves are equipped with springs to assist the valve flap to close.
The sealing surface of the valve seat is made of cobalt-based cemented carbide plasma spray welding. The sealing surface has high hardness, abrasion resistance, abrasion resistance and long service life.
When the pump stops continuous rotation, the spring force closes the valve disc first, thus preventing water hammer.
The spring is made of stainless steel, which has strong corrosion resistance.
