Hydraulic Fail-Safe Actuator

Designed for both surface and subsea applications in conjunction with Magnum Gate Valves, the Hydraulic Fail-Safe Actuator houses a quick disconnect mechanism which allows for fast removal of actuator from valve without disturbing the body/bonnet connection. Once removed, it provides easy access to valve stem packing. In addition, the actuator body totally contains the spring under compression, making field service safer and quicker. Liberal use of wear rings prevents metal-to-metal contact, reducing wear, scoring, and galling. Available for use on valve sizes from 1-13/16” through 9” with API ratings of 2,000 to 20,000 psi and as Fail-Open or Fail-Close to match pressure control requirements and customer applications.

The Magnum Subsea Actuator design has been tested to a water depth of 13,200 ft and meets all specifications for subsea wellhead and Christmas tree applications. In additional testing, the actuator has been cycled 5,000 times at full working pressure, providing reliability and safety in the most demanding subsea operations.
