Characteristics of stainless steel soft-sealed gate valves
- Stainless steel material: The valve body and valve cover of stainless steel soft-sealed gate valves are usually made of 304 or 316L stainless steel, which has excellent corrosion resistance and can resist the erosion of various corrosive media.
- Soft seal design: The seal of the gate valve is made of soft materials with high resilience, such as polytetrafluoroethylene (PTFE) or ethylene propylene diene monomer (EPDM). These materials have good sealing properties and can effectively prevent medium leakage.
- Compact structure: The stainless steel soft-sealed gate valve has a compact design and a small size, which is convenient for installation and saves space.
- Easy operation: The gate valve only needs to rotate the valve stem to open and close, which is simple and convenient to operate, and the length of the handwheel and valve stem can be adjusted as needed.
- Low fluid resistance: The fluid channel of the gate valve is usually designed as a straight-through type, so the fluid resistance is small, which effectively reduces the pressure loss of fluid transportation.
Structure of stainless steel soft-sealed gate valves
Stainless steel soft-sealed gate valves are mainly composed of the following parts:
- Valve body: The function of the valve body is to accommodate and support other parts of the valve, such as seals, valve discs and valve seats.
- Bonnet: The bonnet is connected to the valve body, providing the necessary support for the valve, while accommodating and protecting the valve stem.
- Stem: The valve stem is a key component of the valve operation. It is connected to the valve disc. Rotating the valve stem can drive the valve disc to rise and fall in the valve seat.
- Disc: The valve disc is the core component of the gate valve. It is connected to the valve stem. By rotating the valve stem, the valve disc can be driven to rise and fall in the valve seat to open or close the valve.
- Seal: The seal is used to block the upper and lower channels of the valve to prevent the leakage of the medium.
Stainless steel soft seal gate valve operation mode
Stainless steel soft seal gate valve operation mode mainly includes manual, electric, pneumatic and hydraulic. Among them, manual is the most common operation mode, just turn the hand wheel to operate the valve; electric and pneumatic require external power source for operation; hydraulic requires liquid pressure for operation.
Application fields of stainless steel soft-sealed gate valves
Since stainless steel soft-sealed gate valves have excellent corrosion resistance and good sealing performance, they are widely used in various fluid systems, such as petroleum, chemical, pharmaceutical, food, electricity, etc. In these fields, stainless steel soft-sealed gate valves can be used to adjust flow and pressure, or used as a cut-off device to ensure the stable operation of the fluid system.
