Ledeen Control Systems and Accessory Production
Low-Pressure Pneumatic Controls
For local, remote or automatic control of any low-pressure pneumatic actuator.
Hydraulic Self-Contained Controls
For providing a reliable valve shut-down 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 shut-down response when pre-established set points are reached.
For remote indication of any rotary requirements; primarily for quarter-turn valve actuators.
