MOTOROLA MVME162-253 Cylinder pressure monitor

Low Fugitive Emissions The American Petroleum Institute’s API 624 tests for fugitive emissions to atmosphere for rising stem valves. The tests are conducted at a third party lab and certify that at no point in the test did the valve leak in excess of 100 ppm of methane. Certificates stating that the valve is certified for Low Emissions service are available. For more information, contact your authorized Swagelok sales and service representative.Every Swagelok bleed valve is factory tested with nitrogen at 1000 psig (69 bar). Seats have a maximum allowable leak rate of 0.1 std cm3/min. Shell testing is performed to a requirement of no detectable leakage with a liquid leak detector.

Purge Valves 

Swagelok purge valves are manual bleed, vent, or drain valves. The knurled cap is permanently assembled to the valve body for safety. One-quarter turn with a wrench from finger-tight obtains leak-tight closure on first makeup. Snugging with a wrench ensures closure to the rated pressure with subsequent makeups. 

■ Compact for convenient installation 

■ NPT, SAE, Swagelok tube fitting, and tube adapter end connections

Ordering Information

 Select an ordering number. To order other valve body materials, replace SS in the ordering number with B for brass or S for carbon steel. Example: B-4P-2F When installing a Swagelok purge valve, position the vent hole to direct system fluid away from operating personnel. The vent hole rotates with the cap, changing the direction of discharge as the cap is turned. Always open purge valves slowly. These valves contain no packing, so some fluid weepage will occur when the valves are opened. Operating personnel must protect themselves from exposure to system fluids.
