Uni-Lok 2-Valve Manifolds offer
safety and reliability in a general
purpose design. The simple 2-Valve
configuration allows for easy
block, bleed and calibration of
a static pressure transmitter
or gauge. Valves are available
with either metal seats or replaceable
soft seat inserts. Connections
are 1/2″female NPT on all three
ports.

Information
The pressure-temperature ratings are taken
for ANSI B16.34 for standard class valves
and are based on Class 2500.
Ratings for needle tip designs are based on
specific seat materials.
★ ORIFICE : 3.2mm (0.125″)
★ WEIGHT : Approximate 0.9KG (2lbs)
TESTING
Standard production Test - Each valve on every
manifold is factory tested with nitrogen at
1000psig(68bar) for leakage at the seat, packing,
and shell. Each test is performned to a maximum
allowable leak rate of 0.1 scc/min. |
