PNEUMATIC SCOTCH YOKE

Pneumatic actuators being the most preferred type of all actuators are simple in construction, easier to operate, maintain and troubleshoot, used extensively in process industries for automation of valves & dampers. EPH series offers pneumatic quarter-turn actuators that are rugged, industrial-grade products. Many process industry applications are critical which could affect plant performance are safety-related which demands a high level of reliability, repeatability, and precise control of final elements like valves & dampers. EPH series actuators are designed, manufactured, and rested to meet international standards. EPH series heavy duty actuators are mainly used for higher torque requirement valves like double eccentric butterfly valves, metal seated ball valves and etc.
