Product description
AD pneumatic diaphragm actuators are widely used in surface safety valves,integral wellhead, choke and kill equipment, oil (gas) transmission line, oil(gas) storage shut-down valves and other equipment, with the advantages of smallerweight and easier maintenance. The operating pressure medium can be air,nitrogen or treated wellhead gas. This actuator is suitable for both failclosed and fail open applications.
Features:
01.Over-PressureProtection: This actuator come equipped with pressure relief devices to protectpersonnel and guard against damage to the actuator in case of an over pressurecondition.
02.CorrosionProtection: The actuator housings and all internal components are coated toprevent corrosion due to environmental conditions and control pressure source. 03.Backseat& backseat detection: This actuator come equipped with backseat andbackseat detection hole.
04.Maintenance:The actuators are lightweight and designed for ease of maintenance. Allnon-metallic seals and other quick-wear parts are easily replaceable.
05.PackingIntegrity: A tattletale weep port is located above the packing to providevisual confirmation of stem seal integrity during operation.
