Parallel gate valve
The Parallel Gate Valve is engineered for pipelines requiring precise flow control and leak-proof shut-off. Its parallel gate structure ensures tight sealing, reduced operating torque, and uniform pressure distribution. Suitable for water, oil, gas, steam, and chemical media, it delivers stable performance, low maintenance, and extended service life in demanding industrial applications.
Parallel gate valve
Parallel Gate Valve features a full-bore, parallel-sliding gate design that offers reliable bi-directional sealing. Its flat and parallel gate ensures uniform load distribution and minimizes wear on seats, making it ideal for high-pressure and high-temperature applications.
Constructed from carbon steel, stainless steel, alloy steel, or forged steel, the valve offers excellent strength and corrosion resistance. Manual, electric, pneumatic, or hydraulic actuators can be integrated for automated control.
