Stinger Valve
Never-Lock Traveling Valve
The Stinger is a mechanical-lock traveling valve used in artificial lift wells which utilizes rod pump configurations. Replacing the traditional ball and seat traveling valve, the Stinger's
upper threads connect directly to the valve rod, and the lower threads interface with standard plungers. With a main body of 17–4 stainless steel, the Stinger’s engineered mechanical locking
action prevents high bottom pressure and prevents loss of fluid recovery by locking open on down stroke. In addition, it can reduce operation and well servicing costs while increasing
production.
Design features
- Stainless steel for durability
- Upgrade available for H2S environment
- Low friction sealing surfaces for extended life
- Mechanically opens and closes on every stroke to prevent gas interference or gas lock
Benefits
| Eliminates all gas lock |
| Increases production |
| Allows pumping under extreme bottom pressure without loss of fluid efficiency |
| Reduces operation and well servicing costs |
| Oversized internal ports allow solids to pass through valve |
| Reduces fluid pound |
Fluid Efficiency Advantages
| Engineered rotary locking action prevents high bottom pressure blow-by on upstroke |
| Mechanical actuation opens and closes regardless of pressure differential |
| Prevents loss of fluid recovery by locking open on down stroke |
