7 Series: Fire Safe 2-way, 3-piece Bolted Ball Valve
 |
HOKE’s 7 Series Fire Safe Valves meet demanding application requirements in the production environment of chemical and petrochemical processing facilities. These valves have been tested to and meet the requirements of API 607, 4th edition for soft-seated valves. API 607 measures the ability of a closed soft-seated ball valve to retard the propagation of a fire (downstream and to atmosphere). The 7 Series Fire Safe Valves offer high flow, safety, and flexibility in a variety of end connections and sizes. This series is available in fractional sizes from 1/2″ to 1″ and in metric sizes from 12mm to 25mm in tube and pipe ends.

Typical Applications
- Chemical processing
- Petroleum refining
- Gas distribution
- Hydraulic fluids
Features & Benefits
- Bottom-loaded stem prevents stem blowout for added safety.
- Fully encapsulated bolts are protected from the environment, extending valve life and reducing costs.
- Optional trip-proof or latching/locking handle prevents accidental opening or closing of the valve for a secure process.
- Optional fuse plugs are available on actuators for added safety.
- Fire-safe design retards the propagation of a fire downstream or to the atmosphere, enhancing safety and increasing the range of possible applications.
- Handle provides a visual indicator of whether valve is in the open or closed position, enhancing safety.
- Stem flats provide visual indication of valve position, improving safety.
- Actuators can be mounted to valves without disrupting the packing, seats or seals. Installation time and costs are minimized.
- Special High Tolerance NPT Thread
