Valves give long cycle life

Published: 2-Apr-2001


For service from ;29°C up to 249°C, the Hoke 7188 ball valve is designed to deliver an extended leak-tight cycle life. High temperature performance is achieved with filled PTFE seals. Handling corrosive and viscous fluids in a wide range of applications, they are offered in 316 stainless steel and other materials on request.

Pressure rated to 2,000psig, the units are used for quick on-off service with a visual indication of flow by means of a quarter-turn handle. A colour-coded range of handles allows instant system identification and safety, while a handle locking kit is also available.

The floating ball provides pressure-assisted sealing plus temperature and wear compensation. The patented DynaPak packing gives a leak-tight seal with low torque under vacuum or high pressure.
