Linear actuator SLD-OPST
Environment Temp：-25℃~ +65℃（-40℃~+65℃ optional）
Environment：Can be used for explosive gas atmosphere except coal mine methane gas and except coal mine explosive dust environment .
working time：S2 working system, rated operating time is 30 minutes
Input/output signal(modulating type)：0-10V, 2-10V, 4-20mA
Planet gear design：Planetary transmission has high efficiency, it can realize manual/ electric auto-switching function and without clutch which ensures the safety of the operator
A key setting：After installing the valve, the travel can be set by”A key setting” then feedback signal can be revised automatically and enter the running state
Self-locking protection：Nut screw can lock itself mechanically
Dryer：Moisture resistance can make the housing to dry for a long time and to protect components
Lubrication：The actuator operate stable without maintenance by using low temperature grease.
Disc spring structure：Equipped with disc spring structure, it has a certain per-tightening force which ensure the valve can be fully closed for a long time.
