Product Sheet Unloader Valve
Fullbore circulating valve.
Slickline-retrievable blanking plugs are available to hold differential pressure in the tubing string from above, below, or both. They can be used in low- or high-pressure applications with differential pressures up to 10,000 psi [69 MPa]. High-temperature seals for operating above 300 degF [149 degC] are also available. Some blanking plugs can be easily converted to equalizing standing valves or circulating plugs.
