Introduction
Technical Parameters

Designed for use in high temperature steam and water, this multipurpose gate valve can be used in a wide variety of general purpose applications including vents, drains and isolation of compressors, condensers, heaters, pumps, water lines, heat exchangers, bypass lines, flash tanks, control valves, etc.

·Two inch and smaller valves are available with threaded or socket weld ends as standard.

·Made from one piece, die-forged bodies.

·All internal surfaces are accurately machined to provide maximum performance.

·Renewable seat rings are made from hardened stainless steel, faced with Stellite.

·The wedge is forged, hardened, ground, and lapped to ensure leak free sealing.

·Fully guided wedge, precision machined body channels, for accurate, repeatable seating alignment.

·Graphite packing, complete with braided graphite filament yarn anti-extrusion rings, is standard.

·Standard body and bonnet materials are carbon steel (ASME SA105), alloy steel (ASME SA182 Gr. F11) and stainless steel (ASME SA182 Gr. F316) Trim for steel valves is 13% chrome stainless steel. 316 stainless steel valves have 316 trim.

·Code compliance with ASME B16.34 and the ASME boiler and pressure vessel code, Section I.
