Flowmite® 71 Series 2-way Integral Panel Mount Ball Valve
 |
Used for quick on-off service with a visual indication of flow, HOKE’s 2-way ball valves offer orifice sizes up to 0.25” [6.4mm]. Flomite® valves feature a floating ball design, encapsulated replaceable seats and check seals to ensure leak-tight service and extended service life. |
Typical Applications
- Instrument panels
- High pressure instrument lines
- Gas sampling in pilot plants
- Full flow and shutoff in chromatographs
- Hydraulic test stands
- Gas sampling cylinders
- Handling corrosive and viscous fluids
Features & Benefits
- Quarter-turn handle provides a visual indication of on/off valve position, improving safety.
- Dual encapsulated TFE seats and microfinished ball ensure a leak-tight seal. This combination provides greater valve reliability.
- Dyna-Pak® packing provides a leak-tight seal with low operating torque in vacuum or high pressure applications, helping to prevent fugitive emissions.
- Floating ball provides pressure-assisted sealing and temperature wear compensation for longer valve cycle life and greater value.
- A wide variety of Hoke GYROLOK® end fittings or pipe fittings provide the correct fitting option for the application.
- Special High Tolerance NPT Thread
