Emergency Explosion-Proof Power Durable Electric Gate Valve

A hard-sealed gate valve is a gate valve that uses metal or other hard materials as the sealing surface. It is suitable for high temperature, high pressure, highly corrosive or solid particle-containing media. Compared with soft-sealed gate valves, the sealing surface of hard-sealed gate valves is usually made of metal materials, which has higher strength and wear resistance and can operate stably under more demanding working conditions.

Main features of hard-sealed gate valves
1. High temperature and high pressure resistance:
- The sealing surface of hard-sealed gate valves is usually made of metal materials (such as stainless steel, alloy steel, etc.), which can withstand high temperature and high pressure conditions and is suitable for steam, oil, gas and other media.
2. Strong wear resistance:
- The metal sealing surface has high hardness and wear resistance, and is suitable for occasions containing solid particles or high viscosity media.
3. Corrosion resistance:
- The sealing surface material can be selected from corrosion-resistant alloys (such as stainless steel, Hastelloy, etc.), which are suitable for corrosive media such as strong acids and alkalis.
4. Stable sealing performance:
- The sealing surface of the hard-sealed gate valve is precisely machined and can maintain good sealing performance under high temperature and high pressure.
5. Long service life:
- Due to the high strength and wear resistance of the metal sealing surface, the service life of the hard-sealed gate valve is usually longer.
6. Wide application range:
- Suitable for high temperature and high pressure occasions in the petroleum, chemical, electric power, metallurgy and other industries.

Structure of hard-sealed gate valve
1. Valve body: Usually made of cast steel, stainless steel, alloy steel and other materials, with high strength and corrosion resistance.
2. Valve wedge: The sealing surface of the valve wedge is made of metal material, which fits tightly with the valve seat to achieve sealing.
3. Valve seat: The sealing surface of the valve seat is also made of metal material, which is usually hardened to improve wear resistance.
4. Valve stem: Used to connect the valve plate and the operating mechanism to transmit the opening and closing force.
5. Sealing surface material: Commonly used hard sealing materials include:
- Stainless steel (such as 304, 316)
- Alloy steel (such as Stellite alloy)
- Hard alloy (such as tungsten carbide)

Application scenarios of hard seal gate valves
1. Petroleum and natural gas industry: Used for the control of high temperature and high pressure media such as crude oil, natural gas, and oil products.
2. Chemical industry: Used for the control of strong acid, strong alkali, and corrosive media.
3. Power industry: Used for the control of media such as steam and high temperature water.
4. Metallurgical industry: Used for the control of media such as high temperature gas and dust.
5. Mining industry: Used for media containing solid particles such as slurry and mud.
