Stainless steel gate valves with a metal seat are mainly used in industries and applications where high corrosion and temperature resistance is required.
The Stainless Steel wedge Gate Valve is built for industrial applications that demand high corrosion and temperature resistance. Made from durable stainless steel (1.4408), it handles temperatures up to 450°C and pressures up to 16 bar. With an overall face-to-face length in accordance with EN 558-1, series 14 (F4), this gate valve fits seamlessly into existing pipeline.
Stainless Steel Wedge Gate Valves form some of the most critical components within industrial infrastructure today. They are responsible for regulating liquid and gas flow in a range of industries, from oil and gas to chemical processing, power generation, and water treatment plants. These gate valves are widely used because of their ability to handle high-pressure applications, durability, and long service life. They are suitable for tight shutoff, high temperatures, and highly abrasive media. Our company is among the leading manufacturers of Stainless Steel Wedge Gate Valves in China, and we produce high-quality valves for the international market.
Stainless steel gate valve is the most widely used of all types of valves in modern industry. In this type of valve, a plate like a gate in the valve body moves vertically with the fluid between two matching valve seats, thereby opening or cutting off the flow path. Use it as a cut-off, and when the whole flow channel is fully open, the pressure loss of the medium is minimal at this time.

Application Of Stainless Steel Gate Valves:
Stainless steel gate valve, are mainly used in petrochemical industry, such as ethylene cracking device, polyethylene device and polypropylene device in ethylene production, PTA device (pure terephthalic acid), polyester device and polyester spinning device in chemical fiber production.
304 and 304L are suitable for transportation in weak acid-base medium with less corrosion, such as nitric acid, fertilizer, benzene, oxygen, etc.
316 and 316L are mainly used for medium transportation of strong acids and bases, such as acetic acid, hydrochloric acid, sulfuric acid, etc.
