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

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.
