Product Description

Cemented Carbide Valve Seat with High Hardness, Good Wear Resistance, Compressive Strength and Mechanical Properties

The valve seat is a detachable face part in the valve to support the fully closed position of the spool and form a sealing pair. General valve seat diameter is the maximum flow diameter of the valve. Such as butterfly valve seat material is very broad, all kinds of rubber, plastic, metal materials can be used as the seat material, use elastic sealing material and small thrust actuator for bubble tight seal, seating compression stress make the elastic deformation and packed into with rough surface of metal parts, in order to block all the leak path. The permeability of the material is the basis for a small amount of leakage to the fluid.

The material properties of soft seat should be considered

1) Fluid compatibility, including expansion, hardness loss, permeability, degradation;

2) hardness;

3) Permanent deformation;

4) Degree of recovery after load elimination;

5) Tensile strength and compression strength;

6) Deformation before fracture;

7) Elastic modulus.

Compared with other material, cemented carbide high hardness, good wear resistance, compressive strength and mechanical properties, therefore, widely used for chemical etching, the working conditions of easy oxidation, for all kinds of solution, requirements of stable atmosphere corrosion resistance and oxidation resistance, for the development of all kinds of corrosion resistance, oxidation resistance of hard alloy and hard alloy material applied in various fields, The corrosion of cemented carbide on various acids is mainly the selective dissolution of the bonding phase, so in order to improve the corrosion resistance, Wc-ni alloy with Co bonding phase replaced by Ni, WC-Cr3C2-MO2C-Ni alloy with Cr3C2 or Mo2C, WC-Ti (C, N) or WC-Ti (C, N) TaC non-bonding phase cemented carbides (also known as anti-oxidation carbides) with less than 1.5% bonding phase are widely used Excellent Cr3C2-Ni alloy with Cr3C2 as main component
