Cryogenic Stainless Steel Manual Check Valves

 

  • Globe valve is designed with a stem that moves up and down to regulate flow inside the valve, a disc (ball, composition or plug) and seat, which is generally screwed into the valve body. Seats are designed in plane parallel or inclined to the line of the flow. These types of modulating valves are most commonly used to valve throttle, open or close flow in a system. The advantages are it can be used as a stock check, shorter strokes than other valves such as gates and good at throttling flow.

  • Direct flange-to-flange replacement for standard check valves.
  • Adaptable to a wide range of process applications: low to high temperatures; clean to dirty service; on-off to control.
  • Field performance rivals traditional and specialized check valves.
  • Features & Benefits

  • Designed and engineered specifically for cryogenic service
  • Lapped seating face and PTFE seal to ensure tight shut-off
  • Offset centre of gravity of the disc assembly
  • The disc hits the seat face squarely giving even wear across the seal
