Dual Wall Pneumatic Shut-off Valve
Dual Wall Design: The dual wall construction of our valve provides exceptional strength, durability, and resistance to external forces. The inner wall is responsible for fluid containment and regulation, ensuring leak-proof operation, while the outer wall enhances structural integrity, safeguarding against mechanical stresses.
Pneumatic Actuation: The Dual Wall Pneumatic Shut-off Valve incorporates a pneumatic actuator that enables precise control and reliable shut-off functionality. This actuation mechanism, driven by compressed air, ensures smooth and responsive operation, enhancing process efficiency and control.
Versatile Applications: Our valve caters to the needs of various industries, including oil and gas, chemical processing, water treatment, and power generation. Its versatility allows it to be utilized in fluid regulation, isolation, and flow control applications, meeting the diverse demands of different industrial processes.
Reliable Performance: At our manufacturing factory, we prioritize quality and reliability. The Dual Wall Pneumatic Shut-off Valve undergoes rigorous testing to ensure consistent performance and long-lasting durability. These measures ensure that our customers can rely on our valve for uninterrupted operation and improved process efficiency

Vacuum Insulated Pneumatic Shut-off Valve
The Vacuum Insulated Pneumatic Shut-off Valve, namely Vacuum Jacketed Pneumatic Shut-off Valve, is one of the common series of VI Valve. Pneumatically controlled Vacuum Insulated Shut-off / Stop Valve to control the opening and closing of main and branch pipelines. It is a good choice when it is necessary to cooperate with PLC for automatic control or when the valve position is not convenient for personnel to operate.
The VI Pneumatic Shut-off Valve / Stop Valve, simply speaking, is put a vacuum jacket on the cryogenic Shut-off Valve / Stop valve and added a set of cylinder system. In the manufacturing plant, VI Pneumatic Shut-off Valve and the VI Pipe or Hose are prefabricated into one pipeline, and there is no need for installation with pipeline and insulated treatment on site.
The VI Pneumatic Shut-off Valve can be connected with PLC system, with more other equipment, to achieve more automatic control functions.
Pneumatic or electric actuators can be used to automate the operation of the VI Pneumatic shut-off Valve.
