Pressure Seal Valves

Pressure seal valves are essential for high-pressure fluid applications to protect a system. MSEC, Inc. provides various pressure seal valves with different configurations.

Pressure Seal Valve Distributors

MSEC carries a wide selection of pressure seal valves in various configurations and pressure classes. Pressure seal valves use the pressure of the system to increase seal strength for high-pressure applications. This technology works with a few valve types, including:

  • Globe: Control and stop fluid flow with a movable disc connected to a valve stem.
  • Gate: A rectangular wedge connected to a threaded stem and actuator opens and closes to stop and start fluid flow.
  • Lift check: All check valves are designed to prevent backflow, but the different types use various functions to control fluid flow. Lift valves feature a piston or ball that raises from the seat when upward flow increases the pressure. When the flow stops or reverses, the ball returns to the seat.
  • Swing check: Swing check valves are automatic. A disk responds to pressure flowing in the right direction by opening and staying open. When the pressure decreases, the disc closes.
  • Stop check: Stop check valves operate similarly to a globe valve with a check valve feature that prevents backflow. Unlike other check valves, stop check valves have a perpendicular control mechanism in addition to a vertical one.
