ASME B31.1 VALVES
Needle Valves
Features:
• Unique Oliver design non rotating tip
• Specifically designed for high pressure, high
temperature service
• Anti blow out spindle
• ASTM listed body and seal housing material
• Head unit locking plate
• High temperature pusher design
• Positive bubble tight shut off
• Rolled stem threads for extended valve life
• Stem features a special ten micro inch super
finish on the seal diameter which provides
minimum friction and wear between packing
and stem

Seats: 316 stainless steel metal to metal
(stellite inlaid seat and stellite tip option
available, also soft and metering tip options
consult factory for temperature ratings)
Maximum Working Temperature:
Grafoil packing 540 0 C (1004 0 F) (at reduced pressure)
Maximum Working Pressure:
Standard 6,000 psi (414 bar) at 38 0 C (100 0 F)
High pressure 10,000 psi (690 bar) at 38 0 C
(100 0 F)

CV: 0.46
Handle: T bar (handle locking and position indication available)
Gauge & Two Valve Manifolds
As well as isolation the B31.1 head unit can easily be
incorporated into gauge multiport valves and two valve
manifolds Ideal for isolation, blow down, gauging and block and
bleed applications in direct mounting or remote mounting
configurations also threaded or socket weld and inlet extensions
can be supplied in standard formats.
Three and Five Valve Manifolds
Three and five valve manifolds for differential pressure
measurement applications, both direct and remote mounted
types including various configurations. Many options such as
panel-mounting holes, anti tamper, and designs for integral
steam blocks or other steam tracing requirements. Other specific
manifolds include close coupled range, wall mounting manifold
range as well as dual instrument installation manifolds.
