7300 Series
Quarter-turn Plug Valves
The HOKE ® 7300 Series Plug Valve provides full flow or leak-tight shut off with just a quarter turn. The 7300 is recommended for use in applications where instant on-off and visual flow indication is essential.
Its safe, reliable top- loaded design allows throttling of fluids and thru-port rodding of the valve. The simple design provides easy maintenance and extends valve life.
Applications
• Low pressure air lines
• Test benches
• Chromatographs
• Control panels
• Instrument lines for on/off service
• Isolation valves
• Sampling lines
• Pilot plant instrumentation
Benefits
Safety

7400 Series
Rising Stem Plug Valve
Benefits
Safety
• Back seating is standard
Straight through flow
• In the full open position, the unobstructed, straight through flow path provides maximum flow and rodability
Regulating capability
• A tapered plug and conical seat provide flow regulation and reliable shutoff with very low seating torque, similar to that of a needle valve
Helps reduce fugitive emissions
• Dyna-Pak ® packing provides a leak-tight seal with low operating torque in deep vacuum or high pressure applications
Extended valve life
• Soft Delrin ® seat can absorb solid contaminants and still provide leak-tight shutoff. Delrin ® maintains its toughness and remains springy under a wide range of temperature conditions, enduring high fatigue and resisting both creep and corrosion
Dependability
• All valves are tested for bubble-tight leakage at both seat and packing
• Special High Tolerence NPT Thread
Typical Applications
• Lines which contain small solid impurities
• Instrumentation lines which contain viscous fluids or slurries
• Systems which require routine cleaning
• Systems which require flow regulation and full flow capabilities
