Every Econ SY Series actuator is built to provide long end efficient service with minimum maintenance. The design, engineering and materials used in their construction ensure optimum performance even in the harshest environments.
SY Series actuators are available with symmetric yokes. Symmetric yokes provide more constant torque throughout at both the break points and end positions.
SY Series actuators are manufactured in many different combinations of actuator sizes, cylinder diameters, and designs. Both the double acting (DA) or spring return (SR) designs are available for installation on ¼ turn valves such as ball, butterfly and plug valves. SY actuators are designed for use over a wide range of pressures or temperatures.
The SY actuator is a modular design. A pneumatic or hydraulic cylinder can be attached to either side or both sides. With a large stock of finished and semi-finished components always available, actuators can be assembled and supplied with very fast and reliable deliveries.
The hydraulic valve actuators HyRAV of Eckart, form a full series of double-acting actuators or spring return actuators according to the principle of helical gears. The compact and concentric design of the valve has proven to be excellent in practice and provides the customer with space savings as well as reliability. Moreover, the HyRAV series can be applied in the most severe conditions, i.e. from high vibrations to severe environmental locations, and further, provides a powerful, safe solution for automation of valves. Additionally, the series is easily adapted to all types of valves, what is a result of the generous design of the hollow shaft and adaptable flange types.
