Product description
Parameters

Name: high pressure butterfly valve

Size: 2 "to 10" DN50 to 500;

Pressure: 900Lb ~ 2500Lb; 16MPa ~ 40 MPa

Temperature: -40 ~ 500

Medium: fresh water, sea water

Product features: the valve adopts three eccentric structure, the valve in the open when the seal between the pair can quickly break off, reducing the relative friction between the sealing pair. When the valve is closed, the valve has the function of closing the tight and the sealing ring wear compensation; the convex and the conical valve seat avoids the influence of the solid particle deposition. Valve seat sealing surface using welding carbide on the body, can effectively prevent corrosion and so on; the use of multi-level metal hard seal butterfly valve, the valve body sealing layer for the hard and soft laminated metal pieces of the elastic sealing ring formed a labyrinth seal, with a metal hard seal and elastic soft seal of the dual advantages. In the valve cavity with dust in the case, the valve closed, the formation of a pair of scissors between the mouth of the dust can be eliminated without affecting the seal; valve seal, uniform compression along the circumference, resulting in a welding like effect, making the sealing ring, the role of the general. Flexible seal to ensure zero leakage of liquid or gas". The sealing elasticity enables the valve flap to be closed in the thermal cycling movement, and the torque generated during the closing of the valve seat force, and is uniformly acting around the entire circumference. Flexible sealing bend and full of vitality, to maintain the shape of the valve seat. Compression force along the circumference of the uniform, so that the valve can be closed to achieve two-way close. The sealing elasticity enables the valve body and the valve body to be in contact or expansion, avoiding the danger of being blocked due to temperature fluctuations.
