Brakes, Clutches & Torque Limiters for the Petrochemical Industry<\/h2>

Petrochemical plants<\/strong><\/span> operate processes where valve actuation is critical \u2014 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.<\/p>

EIDE<\/strong> manufactures electromagnetic brakes<\/a>, electromagnetic clutches<\/a>, and LPC torque limiters<\/a> used in valve actuation systems across the petrochemical industry.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Electromagnetic Brakes \u2014 Position Holding on Power Loss<\/h2>

Electric valve actuators require a brake to hold valve position when the actuator is de-energised \u2014 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.<\/p>

EIDE electromagnetic brakes provide secure position holding<\/strong> when de-energised and clean release<\/strong> when the actuator is powered, integrating directly into the actuator drive train without adding complexity to the control system.<\/p>

Electromagnetic Clutches \u2014 Controlled Torque Transmission<\/h2>

In valve actuator systems where torque transmission needs to be engaged or disengaged on demand \u2014 multi-turn actuators, modulating valves, or systems with manual override requirements \u2014 EIDE electromagnetic clutches<\/a> provide precise, repeatable engagement<\/strong> with fast response times and long service life under continuous cycling.<\/p>

LPC Torque Limiters \u2014 Actuator and Valve Protection<\/h2>

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 \u2014 leading to unplanned shutdowns in a process environment where downtime is costly.<\/p>

The EIDE LPC torque limiter<\/strong> 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.<\/p>
