Rotork – Electro-Hydraulic Actuators
Design: Skilmatic Electro-Hydraulic Quarter Turn (SI/EH-QT) and Linear Actuators (SI/EH-L) with manual overide.
Typical Applications: Gas Pipeline.
Torque Output: Quarter Turn — torques up to 600,000 Nm. Linear — thrusts from 1.7 KN — 61 KN as standard. Custom build to suit thrusts up to 150 KN Spring Return or 5,500 KN double acting.
Enclosures: Aluminium, Carbon Steel and Ductile Iron options available depending on unit selected. All have standard 2-pack epoxy coating. Enclosure options - Weatherproof range from IP54 — IP68 4 and Hazardous Area Certifications ATEX and IECEx, depending on actuator selection and requirements.
Voltage: Single Phase, Three Phase and DC supplies (24VDC, 240V and 415V).
Control: Digital Control (two position) — Open, Close, Stop / Maintain, Partial Stroke and ESD 20-60VDC or 20-120 VAC, 5 mA minimum duration 300ms. Analogue Control (modulating) 4-20mA or 0-10 VDC. Position Feedback — 4 — 20 mA.
Optional Fieldbus Control: Pakscan, Modbus, Profibus, Foundation Fieldbus and DeviceNet.
Other Standard Electrical Items: Alarm and Monitoring, Cable Entries, Position Measurement, Limit Switches, Local Controls, Non-Intrusive Setting and Display — LCD / LED’s.
Design Details: The Skilmatic range combine the simplicity of electrical operation with the precision of hydraulic control and the reliability of mechanical fail-safe action. Skilmatic EH Pro actuators provide the ideal solution for two position control, critical safety shutdown, precise modulating control and Partial Stroke Testing (PST).
