This valve is operated by the pressure of the pipeline and is used for various control applications in water supply, fire fighting, industrial, sewage and irrigation systems. The valve can be closed or modulated using the line pressure or an external separate pressure source that is equal or higher than the line pressure.

Dorot valves are made for easy, inline maintenance, executed also by unskilled personal using basic tools. There are no shafts, bearings or seals that may corrode and there is no wear and tear by dirty abrasive water or chemicals.

OM series electric actuators offer a range of 35 Nm~4500 Nm torque. The actuator comes standard with NEMA 4X (IP67) environmental rating. All models are ISO 5211 compliant and have a visual position indicator. The manual override can be operated without clutch and brake under our research and development.
