Application

2 Way Manifolds – Static pressure and liquid level applications
3 & 5 Way Manifolds – Most differential pressure transmitters with both female and flange process impulse line connections

Application

UNILOK valves are comply with NACE MR- 0175/ISO 15156 for sour oilfield application or NACE MR-0103 for petroleum refining operations.
To order, add-N to the end of part number

Cleaning

UNILOK valves are free from machine oils, loose particles and grease throughout the close cleaning process.

Testing

Every valve is 100% factory tested with air and nitrogen at 1000psig(69bar) for leakage at the seat and packing. Each test is performed to a maximum allowable leak rate of 0.1scc/min.
Hydrostatic shell test to be performed at 1.5 time of the working pressure is available as optional

Important Notification

Proper installation, materials compatibility, operation and maintenance of these valves are the responsibility of the user. The total system design must be taken into consideration to ensure optimal performance and safety.
The packing adjustment may be required during the valve’s service life.
