Product description

AH actuator is a piston type hydraulic actuated device, which is very suitable for surface safety valve, oil (gas) transmission line, manifold valve and collection pipeline, as well as casing safety valve and storage valve. The operating pressure medium is hydraulic oil. This actuator is suitable for both fail closed and fail open applications. Features 01.Over-Pressure Protection: This actuator come equipped with pressure relief devices to protect personnel and guard against damage to the actuator in case of an over pressure condition.  The pressure relief device is easily inspected and is field-replaceable.. 02.Corrosion Protection: The actuator housings are internally and externally coated to prevent corrosion due to environmental conditions.  All internal components are either stainless steel or are coated to prevent corrosion due to any contamination that might be present in the control pressure source. 03.Backseat & backseat detection: This actuator come equipped with backseat and backseat detection hole. 04.Maintenance: The actuators are designed for ease of maintenance. All non-metallic seals and other parts are easily replaceable. 05.Packing Integrity: A tattletale weep port is located above the packing to provide visual confirmation of stem seal integrity during operation. 06.Preset drift: Factory preset drift eliminates the need for field adjustments.
