CAST STEEL VALVES
GATE, GLOBE & CHECK / HIGH PRESSURE & TEMPERATURE SERVICE
Cast steel valves manufactured to API 600 and 603 and tested to API 598. Gate valves use an outside screw and yoke with a flexible wedge, globe valves a conical plug disc for throttling, and swing checks a low pressure drop closure. A broad material range covers carbon, alloy, and stainless steel with stellite-overlaid trim.

PRESSURE SEAL VALVES
GATE, GLOBE & CHECK / HIGH PRESSURE & TEMPERATURE SERVICE
Pressure seal gate, globe, and check valves built for high-pressure, high-temperature service. The pressure seal bonnet tightens as internal pressure rises, giving an efficient seal with weight savings and easier maintenance. The line covers gate, globe, swing check, tilting disc, piston, and stop check patterns to ASME B16.34.
