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.

Specifications

- Connection:1/2″Female NPT to 1/2″Female NPT
- One-piece, high strength body construction for safety no welding used
- Stems feature an non-rotating top with an easily replaceable soft insert
- Bonnet lock pin prevents accidental valve disassembly
- 316 stainless steel construction for superior corrosion resistance
- Bonnet-to-body seals are metal-to-metal-no O-Rings used
- Mounting holes provided for self-supporting applications
- 100% pressure tested for shut-off and at all seals
- Manifolds feature a 4:1 safety factor

Manifold Selection 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.
