1. Applicable medium Water, steam, oil, etc. 2. Structural features 1. The valve body is forged integrally, with high strength, reliable material, beautiful appearance, and welded structure for valve body and pipeline connection. 2. Sealing surface adopts hard alloy hardfacing, high hardness, wear resistance and corrosion resistance, zero leakage
Structural advantages and characteristics 1.Single structure, light weight, good rigidity, easy to maintain; 2． 2. The thrust of the spring enables the valve disc to handle the closed position even when no medium pressure is used; Good support method makes the valve disc and valve seat no matter the installation position of the valve
H81X-10 / 16 grooved muffler check valve H81X-10 / 16 grooved muffler check valve is mainly installed at the pump outlet. The valve is composed of a valve body, a valve seat, a valve disc, a valve stem, a spring and the like. When the pressure at the water inlet is greater than the pressure at the outlet and the spring, the valve opens; when the pump stops, the valve flap is under the pretension of the spring
H81X-10 / 16 grooved muffler check valve is mainly installed at the pump outlet. The valve is composed of a valve body, a valve seat, a valve disc, a valve stem, a spring and the like. When the inlet pressure is greater than the outlet and spring pressure, the valve opens; when the pump stops, under the pre-tension of the spring, the valve flap closes quickly at the head drop line, extremely short
Product introduction: Non-return valve is usually used to prevent the medium from flowing backward. Non-metallic elastically sealed valve has a maximum allowable leakage of zero. Metal-sealed valve has a maximum allowable leakage of 0.1 × DNmm (3) / s. Therefore, qualified metal-sealed valves will have a small amount of leakage. Therefore, no leakage field is required for check valves.
