Active Pressure Relief Valve

Use the DTI Active Pressure Relief Valve to prevent BHA over-pressure and protect tools.

The DTI Active Pressure Relief Valve opening pressure is set at surface so that when BHA pressure increases, flow ports to the annulus open. When the flow rate is increased, the gradual valve opening mechanism maintains the pre-set BHA pressure by diverting a controlled volume of fluid to the annulus.

A metal to metal sealing mechanism maintains Active Pressure Relief Valve opening pressure reliability and closes when flow rate is reduced. The valve is simple to adjust and operate and can be used in a variety of applications.

  • Protect motors from accidental overpressure
  • Run with Impact Hammers to maintain consistent pressure at the Shifting Tool
  • Increase annular flow rate while maintaining consistent BHA pressure

  • Easy to adjust opening pressure
  • Metal to metal seal mechanism
  • Eliminate overpressure damage to tools in BHA
  • Eliminate Shifting Tool oscillation when run below Impact Hammers
  • Increase annular velocity without pumping through sensitive tools
