GE's check valves are typically designed for Marman, Wiggins, Pressure Science, Gamah, bulkhead/bolt type or special flanges.

Seals are metal-to-metal or elastomeric-to-metal.

Usually, the valves are equipped with flapper stops that prevent flapper oscillation during forward flow conditions, and an over-the-center condition upon flow reversal.

Flow restriction can be provided, if required, in either the upstream or downstream directions.

Features:

• One-inch to 10-inch diameters

• Working fluid temperatures up to over 1200 ºF (649 ºC)

• Working fluid pressures up to over 800 PSIG

• Working fluids can be air or fresh water

Aluminum, stainless steel, or Inconel materials
