Angle Pro Relief

Angle Pro Relief Bottom Hole Spring

The Angle Pro Relief Bottom Hole Spring is designed to provide 100% seal efficacy even at deviations of up to 65 degrees. This relief spring can maintain an overbalance of 60 PSI over the pressure beneath the seating surface, handling approximately - 2/5th of a barrel in 2 3/8-inch tubing and 1/2 barrel in 2 7/8-inch tubing.

Its superior sealing capability meets or exceeds that of any relieving bottom hole spring currently on the market. The standard configuration includes an Inconel X750 spring and a tungsten carbide ball and seat, ensuring a long service life even in harsh environmental conditions.
