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
For service from -29 deg C up to +249 deg C, 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 to ensure extended leak-tight cycle life.
The high temperature performance is achieved with filled TFE seals.
Handling corrosive and viscous fluids in a wide range of applications, the valves are offered in 316 stainless steel and other materials on request.
Pressure rated to 2000 psig, these 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, and a handle locking kit is also available.
The floating ball provides pressure-assisted sealing plus temperature and wear compensation, while the patented 'Dyna-Pak' packing gives a leak-tight seal with low torque under vacuum or high pressure.
Standard end connections are 1/4in or 3/8in Gyrolok and 1/4in female NPT.
