Brakes, Clutches & Torque Limiters for the Petrochemical Industry
Petrochemical plants operate processes where valve actuation is critical — flow control, pressure regulation, emergency isolation. The actuators driving these valves must respond precisely, hold position reliably, and withstand the mechanical demands of continuous or intermittent duty cycles in environments that are often hazardous, corrosive, or subject to strict safety regulations.
EIDE manufactures electromagnetic brakes, electromagnetic clutches, and LPC torque limiters used in valve actuation systems across the petrochemical industry.
Electromagnetic Brakes — Position Holding on Power Loss
Electric valve actuators require a brake to hold valve position when the actuator is de-energised — whether at the end of stroke, during a process hold, or following a power failure. An uncontrolled valve movement in a petrochemical process can have serious consequences.
EIDE electromagnetic brakes provide secure position holding when de-energised and clean release when the actuator is powered, integrating directly into the actuator drive train without adding complexity to the control system.
Electromagnetic Clutches — Controlled Torque Transmission
In valve actuator systems where torque transmission needs to be engaged or disengaged on demand — multi-turn actuators, modulating valves, or systems with manual override requirements — EIDE electromagnetic clutches provide precise, repeatable engagement with fast response times and long service life under continuous cycling.
LPC Torque Limiters — Actuator and Valve Protection
Valve actuators are exposed to peak torque events at the end of the stroke, on mechanical obstruction, or when process conditions change unexpectedly. Without protection, these peaks damage gearboxes, actuator components, and the valve itself — leading to unplanned shutdowns in a process environment where downtime is costly.
The EIDE LPC torque limiter mechanically disconnects the drive train the instant torque exceeds the preset threshold, protecting both the actuator and the valve from overload damage. Once the overload condition is resolved, the torque limiter resets and normal operation resumes.
Key characteristics of the LPC series:
- Purely mechanical actuation — no electrical signal required to disengage
- Precise, adjustable tripping torque to match actuator and valve specifications
- Compact design suitable for integration into standard actuator drive trains
- Reliable performance in demanding industrial environments
EIDE provides configurable solutions for valve actuation applications across the petrochemical industry, with products selected and configured to match the specific torque, duty cycle, and environmental requirements of each installation. Contact our technical team to discuss your application.
