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
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
