Metal gasket classification there are three main types:

1, octagonal, and oval pad - flange sealing surface is suitable for the trapezoidal groove

2, tooth form is in metallic flat gasket seal surface machining taper tooth corrugated - applies to concave and convex flange sealing surface

3, lens pad - is suitable for the lens type flange sealing surface

metal gasket pure iron, mild steel, stainless steel, aluminum and other materials

metal gasket sealing surface of high machining accuracy and surface roughness requirements, bolt clamping force is very big, used in high temperature and high pressure valves

metal package graphite gaskets

composed of thin metal cladding annular asbestos gasket. Commonly used in concave and convex flange sealing surface. Suitable for high temperature and pressure of the Industrial Valves

spiral wound gasket

consists of corrugated metal belt and sealing material belt winding. With steel belt - Asbestos, steel belt - Ptfe, steel belt - Flexible graphite, etc. Commonly used in concave and convex flange sealing surface. Suitable for high temperature medium pressure valve.

ptfe gasket

general for mortise type sealing surface, mainly have ptfe teflon two materials and glass fiber. Used in all kinds of low temperature stress of the corrosive medium.

asbestos rubber gasket

is suitable for the smooth type flange sealing surface, concave and convex flange sealing surface and mortise flange sealing surface. Advantage is better corrosion resistance and thermal stability, good plasticity, with smaller pressure force guarantee seal. Defect is low intensity, easy to stick to the flange sealing surface. Asbestos rubber gasket has universal asbestos board, anticorrosive asbestos board, asbestos board, acid is commonly used in asbestos board, oil resistant asbestos board, asbestos board clip wire and other materials. Used in the high temperature medium pressure valve graphite gaskets

ping made of flexible graphite gaskets, suitable for high temperature and strong corrosive medium.

xiangtan in the production of piston reducing Industrial Valves, drive mode for hydraulic control, flange connection way, structure composite piston, sealing structure choose soft seal and hard seal, PN0 pressure range. 1 - 4. 0Mpa( Special pressure, nominal diameter DN65 - 400 mm, the material can choose cast iron, cast steel, stainless steel. As a result of the valve using range is very wide, and the working condition of the same kind of valve in different occasions have different collocation, if you are professional, welcome you to our company to inquire. The company has professional and technical personnel for you!

In the past few decades, y gate valve production has increased because of the use of wedge gate valve.
With continuous operational improvements, expanding capacity and a strong competitive position for serving strategic domestic markets, Shenzhen Mech Valve Trading Co., Ltd. are positioned for long-term growth that will benefit our customers and investors.
Further dialogue of Mech Valve between the approaches, the chapter concludes, could lead to actionable advice on more robust policies that drive both structural change and competitiveness upgrading.
