KSB Ennacto Single-Acting Hydraulic Actuator

The KSB ENNACTO is a single-acting hydraulic actuator that can be mounted on quarter-turn valves (butterfly valves or ball valves). The top flange is to ISO 5211. The DYNACTO has a control pressure up to 120bar. It can be mounted on various types of valve stem ends (square end, flat end or key). Force transmission is done via rack-and-pinion, and the scotch-yoke or patented Amri yoke kinematics provides output torques of up to 16000 Nm which are ideal for actuating quarter-turn valves. The ENNACTO has a reset to fail-safe position, which is effected by means of a pressurised nitrogen cartridge if the control fluid supply is interrupted. The ENNACTO is equipped with a visual position indicator and adjustable travel stops for open/closed position as standard.
