Z41H American standard gate valve is closed, sealing surface can only rely on medium pressure to seal, that depend on medium pressure, the disc will be to the other side of the valve seat sealing surface pressure to ensure that the seal face seal, this is the seal.

Working principle of the product and application:

Z41H American standard gate valve is closed, sealing surface can only rely on medium pressure to seal, that depend on medium pressure, the disc will be to the other side of the valve seat sealing surface pressure to ensure that the seal face seal, this is the seal. Most is adopt compulsory seal gate valve, the valve is closed, to rely on outside force forced the ram pressure to the seat, to ensure the sealing surface sealing.

Open valve, when the gate hoisting height is equal to valve size 1:1 times, fluid

     Product structure features:

1. The pressure valve USES precision casting technology on casting, the surface quality of the handwheel using malleable iron casting, molding with handle, appropriately increase friction, easy to open. And have obvious "on", "off".

2. Use high ni ductile iron stem nut, "T" shape screw transmission torque in conjunction with the valve stem.

Equipped with oil cup, 3. The cover can be added solid lubricating oil regularly, maintain easy opening and closing.

4. Packing gland and compression set of fission design, guarantee the concentricity of the stem. Reasonable packing design, ensure no valve leakage, accord with environmental protection requirement.

5. Cover with sealing ring, in line with the American petroleum institute API standard.
