Pneumatic parallel double gate valve
The Pneumatic Parallel Double Gate Valve features dual parallel gates actuated pneumatically for smooth, low-torque operation and enhanced sealing reliability. Designed for oil, gas, chemical, and power industries, it minimizes wear, allows bi-directional flow isolation, and integrates easily with automated systems, providing long service life in demanding industrial conditions.
Pneumatic parallel double gate valve
The Pneumatic Parallel Double Gate Valve is a high-performance isolation valve engineered with two parallel gates to maintain uniform sealing and reduce operating torque. Pneumatic actuation allows fast opening/closing cycles and remote control, suitable for fully automated pipeline systems.
