Circor Instrumentation product story
Edited by the Engineeringtalk editorial team

Hoke 7 Series zero-leakage ball valves employ energised stem packing technology extending service life up to 50,000 cycles and live-loaded seats that compensate for wear and temperature cycling.
The latest Hoke 7 Series zero-leakage ball valves now available from Circor Instrumentation employ energised stem packing technology extending service life up to 50,000 cycles and live-loaded seats that compensate for wear and temperature cycling without adjustment.
Totally leak-tight in operation over their entire pressure range, these two- and three-way ball valves are offered in 316 stainless steel as standard or special alloys to specification.
Fast on/off operation and visual indication of flow are provided, and the valves are supplied either with a manual handle or an optional factory-assembled pneumatic actuator that reduces installed cost.
Grounded stems prevent static discharge for safety.
