2-Valve Manifold (2VMNT-8N-SS)

catalog

Kor-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 a non-rotating tip 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

Safe Manifold Selection
When selecting a manifold, the total system design must be considered to ensure safe, trouble-tree performance. Valve function, materials compatibility, adequate ratings, proper installation, operation, and maintenance are the responsibility of the system designer and user.

Manifold Selection Information
The pressure-temperature ratings are taken for ANSI B16.34 for standard class valves and based on Class 2500.
Rating for needle tip designs are based on specific seat materials.

★ ORIFICE : 3.2mm (0.125")
★ WEIGHT : Approximate 0.9KG (2 lbs)

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 performed to a maximum allowable leak rate of 0.1 scc/min.
