The Uni-Lok Pipe to Pipe
3-Valve Manifold is a general purpose
design for connection system impulse
lines and transmitters. This manifold
consists of two block balbes and an
equalizer valve. Connections are 1/2″Female
NPT on 2-1/8″(54mm) centers for safety,
an bonnet lock pin is standard.
Specifications
- CONNECTION:1/2″Female NPT to 1/2″Female
NPT
- One-piece, high strength body construction
for safety no welding used.
- 316 stainless steel construction for
superior corrosion resistance.
- Bonnet Lock pin prevents accidental
valve disassembly.
- 2-1/8″(54mm) port centerline dimension
for proper alignment.
- 100% pressure tested for shut-off
and at all seals.
- Manifolds feature 4:1 safety factor.

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.

TESTING
Standard production Test - Each valve on every
manifold is factory tested with nitrogen at
1000psig(68bar). The test is performed to
a maximum allowable leak rate of 0.1scc/min.
at the seat and no detectable leakate at the
packing and shell areas as measured by leak
detector. |
