N/A
Energized PTFE stem seal
- Exceeds 50,000 cycles, reducing costs of ownership (For best results use a filter upstream to the valve. Dirty, errosive and corrosive fluids may affect the cycle life of the valve, cycle life is based on working pressures less than 150 psig.)
- No packing adjustments required, providing operator peace of mind
- Low operating torque for ease of operation
Live-loaded seats
- Compensate for wear and temperature cycling with zero leakage, providing excelling durability and reliability. Zero leakage per API 598.
- Ensure leak tight performance over entire pressure range simplifying ball valve specification and installation, saving time and expense.
- Optional vented ball equalizes pressure between ball orifice and center body cavity
Static -grounded stem
- Prevents static discharge for added safety
- Quarter turn handle provides a visual indication of on/off valve position, improving safety
- Stem flats provide visual indication of valve position, improving safety
- Bottom-loaded stem prevents stem blowout for added safety
- Optional trip-proof or latching / locking handle prevents accidental opening or closing of the valve for greater security and safety
- Fully encapsulated bolts are protected from the environment, extending valve life and reducing costs
Valves are designed, manufactured and tested in compliance with: ANSI/ASME B16.34 (valves: flanged, threaded, and welding end) (When BI6.34 (option B) is selected, testing is conducted in accordance with these specifications.), API 608 (metal ball valves: flanged, threaded and welding end), API 598 (valve inspection and test), and MSS SP-99 (instrument valves)
- Industry standards ensure reliability and integrity of components and systems
Top-mount actuators and brackets are designed and manufactured in compliance with ISO 5211 (industrial valve: part-turn actuator attachment)
- Allow HOKE 7 Series to easily interchange with a wide variety of pneumatic actuators
- Allow user to easily convert manual valve to pneumatic operation in the field
- Special High Tolerance NPT Thread
