Features

Rated to ASME 800 limited class for use in all applications requiring 800 limited class ratings or below.
Available in 1" nominal pipe size with ⅛", 3/16", ¼" or 5/16" orifice, depending on desired flow capacities.
A micrometer dial position indicator allows fast, precise and repeatable settings.
Socket weld end connections.
Both disc and disc seat are hard faced with Stellite for erosion resistance.
Seating surfaces are ground and lapped for tight shut off, eliminating double valving requirements.
The integral stem disc is faced with stellite, then ground and lapped for accurate, leak-free sealing.
The disc is tapered for maximum controllability over the full stroke of the valve.
Standard material is carbon steel (ASME SA 105) body with 13% chrome stainless steel trim.
One-piece drop forged body.
Graphite packing, complete with braided graphite filament yarn anti-extrusion rings, is standard.
All 5505 series valves comply with ASME B 16.34 and the ASME boiler and pressure vessel code, section 1.
