Forged Steel Gauge Valve
|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 Grade 1 specification. Stem and reversible seat Type 303 stainless. Steam and nipple packing rings are secured by identical two-bolt packing yokes.
