Vacuum Insulated Pneumatic Shut-off Valve
The Vacuum Insulated Pneumatic Shut-off Valve, sometimes referred to as a Vacuum Jacketed Pneumatic Shut-off Valve, represents a leading-edge solution within our comprehensive line of Vacuum Insulated Valves. Designed for precise and automated control, this valve regulates the opening and closing of main and branch pipelines in cryogenic equipment systems. It’s the ideal choice where integration with a PLC system for automated control is required, or in situations where valve access for manual operation is limited.
At its core, the Vacuum Insulated Pneumatic Shut-off Valve builds upon the proven design of our cryogenic shut-off/stop valves, enhanced with a high-performance vacuum jacket and a robust pneumatic actuator system. This innovative design minimizes heat leak and maximizes efficiency when integrated within Vacuum Insulated Pipes (VIPs) and Vacuum Insulated Hoses (VIHs).
In modern facilities, these are commonly integrated with Vacuum Insulated Pipe (VIP) or Vacuum Insulated Hose (VIH) systems. Pre-fabrication of these valves into complete pipeline segments eliminates the need for on-site insulation, reducing installation time and ensuring consistent performance. The Vacuum Insulated Pneumatic Shut-off Valve’s pneumatic actuator allows for remote operation and seamless integration with automated control systems. This valve is often a key piece of cryogenic equipment when paired with these other systems.
Further automation is possible through connection to PLC systems alongside the Vacuum Insulated Pneumatic Shut-off Valve with other cryogenic equipment, allowing more advanced, automated control functions. Both pneumatic and electric actuators are supported for the valve automating the operation of cryogenic equipment.
