Documentation

Direct contact, metal-to-metal seating, make the globe valve ideal for most shut-off applications. Designed for ASME Boiler and Pressure Vessel Code, Section I applications including vents, drains, bypass systems, gauge shut-off, instrument isolation, chemical cleaning systems, control valve isolation, auxiliary steam lines, heat exchangers, or wherever reliable, leak-tight performance, under high temperature/pressure conditions, is required.

Features & Benefits:

The 5500 has a fixed, repairable seat overlaid with Stellite or equal hardfacing.
Available with threaded or socket weld end connections as standard.
Valves are made using one-piece, die forged bodies.
All internal surfaces are accurately machined to provide maximum performance.
The disc is hardened, ground, and lapped to ensure leak free sealing over the valve’s full pressure/temperature range.
A precision machined, integral backseat is standard.
Both seats are designed for accurate, repeatable, seating alignment.
Corrosion inhibited graphite packing and braided graphite filament anti-extrusion rings are 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 316 stainless steel valves have 316 trim.
Also available in a variety of body and trim materials.
A needle disc option is available.
Code compliance with ASME/ANSI B16.34 and the ASME Boiler and Pressure Vessel Code, Section I.
