Pressure Sealed Check Valves are intended for high pressure, high temperature applications in all types of fluid except where severe coking is a factor. The design and material selections provide excellent service in steam-generation stations, industrial chemical plants and thermal power plants. Most Pressure Seal valves are offered in Cast Steel and Forged Steel body designs. These options make the ZGV Pressure Seal product line an excellent choice for users with various application requirements.
Pressure Sealed Check Valves provide the most efficient flow passage and sealing features possible, resulting in significant weight savings, easy installation and in-line maintenance.
Pressure Seal Valves are manufactured and tested in strict accordance with the following standards:
▲ASME B16.34 ▲ASME B16.10 ▲ASME B16.25 ▲API 598
Pressure Seal check valves are designed for reliability in high velocity service applications to prevent backflow. The check valves are designed to operate in either vertical or horizontal pipe runs. Seating surfaces are hardfaced with Stellite to provide high cycle capability. The swing check design offers better flow characteristics than a tilting disc design with higher flow area. The tilting disc is a non-slam design which minimizes the potential for water hammer. Pressure Seal tilting check valves feature a fitted disc that's guided to ensure an effective tight seal and to minimize vibration.
