FORGED STEEL GAUGE VALVES

For Steam** Pressure up to 1500 PSI
The steel valve is lever-operated, outside screw and yoke design, and is recommended for steam service
up to 1500 PSI @ 600°F. Forged steel body to ASTM A105 specification. Supplied with 303 SS and 420F replacement seat. Stem and nipple packing rings are secured by identical two-bolt packing yokes. Quadruple stem thread permits full open or shut position in one-quarter turn. Bronze stem bushing prevents seizing, and is located outside of valve body, thus unaffected by high temperature or corrosive fluids. Bottom of lower valve contains 1/2” pipe tap and female socket weld connection for gauge blowdown.

 

The EFI SG854 valves have 3/4” male pipe connections, while the EFI SG860 valves are fitted with ASME 3/4” 900# RF* flanges. EFI SG855 valves have the same connections as the EFI SG854, but feature a union connection on the tail piece. Special connections can be furnished on request.
Complete set includes two 5-foot lengths of chain, with handles to indicate open or closed position of valves, as required by the ASME Boiler Code.

When ordering: Specify Ernst Flow Industries Model number, 3/4” threaded or flanged connection. Specify gauge centers, operating pressure and temperature.
**WARNING: For use with POWER BOILER SATURATED STEAM APPLICATIONS ONLY. MODEL EFI SG STEEL GAUGE VALVES ARE NOT TO BE USED WITH SUPERHEATED STEAM.
