Ball valves maintain zero leakage over
cycle life
Designed to exceed 100,000 cycles with zero leakage, Hoke 70/71 Series unidirectional ball valves have live-loaded seats that compensate for wear and temperature cycling to ensure leak-tight operation
Designed to exceed 100,000 cycles with zero leakage, Hoke 70/71 Series unidirectional ball valves introduced by Circor Instrumentation have live-loaded seats that compensate for wear and temperature cycling to ensure leak-tight operation over their entire pressure range High-performance rating of the valves is achieved with two new stem seal designs that also ensure system compatibility: the DL delta design and the TL energised Teflon which is meant for use where media compatibility is essential

The Hoke 7188 ball valve, added to the Flomite 71 Series of two-way integral panel mount valves, features floating ball design, encapsulated seats and check seals for extended leak-tight cycle life
The 70 Series has a welded end-fitting that prevents accidental disassembly, with models providing operating pressures up to 414 bar at 21C and temperature ranges of -40 to +177C.
The 71 Series valves have a gasketted end-fitting allowing rebuilding.
Both series have a quarter-turn handle for quick on/off service with visual indication of valve position, and are available with factory-assembled pneumatic or electric actuators.
A wide range of connection types and sizes up to 3/8in and 10mm is readily available.
These ball valves are suitable for applications in the chemical, analytical, sampling system and instrumentation industries.
