3-Valve Manifold (3VMNT-8N-SS)
catalog
The Kor-Lok Pipe to Pipe 3-Valve Manifold is a general purpose design for connecting system impulse lines and transmitters.
This manifold consists of two block valves and an equalizer valve.Connections are 1/2" Female NPT on 2-1/8"(54mm) centers. For safety, a 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.
* 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 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
Needle Tip : 3.2mm (0.125")
Plug Tip : 6.4mm (0.250")
★ WEIGHT : Approximate 2.3KG (5lbs)
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 0.1 scc/min. at the seat and no detectable leakage at the packing and shell areas as measured by leak detector |
