Function

This valve allows for controlled venting or dumping the fluid out of the tubing.

Advantages

  • Less tension needed to unseat pumping assembly.
  • Eliminates washing off of cups on hold down tool by venting fluid through the dump valve.
  • Easy to operate by pulling up against top of pump barrel.
  • Can be run with conventional rod pumps or with wireline conveyed pumps.
  • Venting is controlled by lifting the plunger to the top of the barrel and lowering to stop the venting when desired.
  • Can spot chemicals or wash out flour sand from around the pump barrel. An advantage is the ability to spot chemicals between the pump barrel and tubing, which is usually a dead fluid area.
  • It may be desired to melt paraffin by putting hot fluids down the tubing.

This vent valve allows fluids to enter the tubing at the top and exit at the bottom. The amount of fluid required is pumped into the top of the tubing. Vent valve is then closed by lowering pump barrel back to original position.

Function

This device is designed to reduce GAS LOCKING. Upstroke The fluid enters to the valve (1) and the ball valve opens (2) with 50 psi pressure allowing the fluid to flow to the surface.
Downstroke The ball valve closes (3) causing the hydrostatic pressure to be held above the valve (4) with no fluid movement.

Standing valve

UpstrokeThe fluid enters to the valve (1) and the ball valve opens (2) with 50 psi pressure allowing the fluid to flow to the surface.

DownstrokeThe ball valve closes (3) causing the hydrostatic pressure to be held above the valve (4) with no fluid movement.
