Ideal solutions for space-constrained installations
Application-specific torque mechanism
For high-pressure hydraulic applications, a small helical spline mechanism is used with a small piston diameter to generate high torque outputs.
Typical application: Quarter-turn hydraulic actuators are used for on/off or modulating control of any ball, plug, or butterfly valve utilizing hydraulic actuator supply.
Typical application: Quarter-turn pneumatic actuators are used for on/off or modulating control of any ball, plug, or butterfly valve utilizing compressed air, natural gas, or nitrogen actuator supply.
Typical application: Linear pneumatic actuators are used for on/off or modulating control of any gate valve or rising stem ball valve utilizing compressed air, natural gas, or nitrogen actuator supply.
LEDEEN Series DiM electric actuator for on/off or modulating control of any multi-turn, partial turn, or linear valve in oil and gas applications.
Enclosed Motor – Totally enclosed, not ventilated (TENV) motor
The integration of the LEDEEN electric actuators into a control system is possible via a multitude of fieldbus connections or via a free-configurable, hard-wired interface. All fieldbus devices can be delivered with the common redundancies, to help enhance system safety and reliability.
SIMA Master Station
System Integration -The SIMA master station solution integrates field devices, like actuators, into an automation environment and supports a variety of protocols such as PROFIBUS DP and Modbus RTU.
LEDEEN hydraulic subsea actuators are specifically designed for shallow-water and deepwater applications. Both actuator types, shallow-water and deepwater series, can operate with a supply pressure up to 3000 psig (207 barg).
Available as double acting or spring return
Typical application: Quarter-turn gas-over-oil actuators are used for on/off control of any natural gas transmission ball or plug valve utilizing a high-pressure natural gas or nitrogen actuator supply.
Typical application: Linear gas-over-oil actuators are used for on/off control of any natural gas transmission gate valve utilizing a high-pressure natural gas or nitrogen actuator supply.
Low-Pressure Pneumatic Control System
For local, remote, or automatic control of any low-pressure pneumatic actuator.
Hydraulic Self-Contained Controls
For providing a reliable valve shutdown capability when an external power source for the actuator is either not available or not dependable.
High-Pressure Gas Controls
For local, remote, or automatic control of any high-pressure gas actuator utilizing a natural gas or nitrogen supply.
Hydraulic Power Units
Provides a reliable high-pressure hydraulic output as a power source for hydraulic actuators.
Electronic Linebreak Controls
For monitoring pipeline operating conditions to quickly detect pressure trending toward abnormally high or low rate-of-drop values and accurately monitor those trends for an automatic shutdown response when pre-established set points are reached.
For remote indication of any rotary requirements; primarily for quarter-turn valve actuators
