The valves are ideal for applications when zero leakage and frequent operation are demanded. They are
used globally in gas processing plants using molecular sieve systems in switching service.
The valve’s top-entry design provides convenient access for in-line inspection and repairs, when required. For
environmental protection, injectable packing can be replenished while valves are under full line pressure on enclosed bonnet
models.
Rising Stem Ball Valve
• No Rubbing Between Sealing Surfaces The tilt-and-turn action eliminates seal abrasion,
which is the major cause of seat wear in conventional ball, gate and plug valves• Top-entry Design
In-line inspection and repair, after system depressurizing, simplifies maintenance
