Ledeen SY Series

LEDEEN SY Series Gas-Over-Oil and Direct Gas Actuators Modular Assembly Consistent engineering design and efficient modular assembly. This leads to increased flexibility. Double acting, single cylinder or dual cylinder are combinations which are available for specific pipeline application requirements. Typical application For on /off control of any natural gas transmission ball or plug valve. It utilizes the high-pressure natural gas from the pipeline with a gas-over-oil configuration. Standard Features ot the Quarter-Turn Gas-Over-Oil Single or dual-cylinder models available Torque outputs to 5,700,000 in-lb (644,000 N·m) Open and close travel stops provide ± 3 degrees minimum Scotch yoke mechanism generates powerful opening and closing torque outputs Steel fabricated frame provides rugged foundation of modular assemblies Nickel-plated side load bar with guide block for effective elimination of piston rod deflection and stem side loading Bronze bushing interfaces provide low-friction support of sliding and rotating components Aluminum bronze sliding blocks for a low-friction, low-stress pin connection Steel cylinder assembly provides robust pressure containment for all conditions Electroless nickel-plated cylinder ID ensures excellent sealing surface with excellent corrosion resistance Buna piston seal configurations specifically designed for gas-over-oil applications Composite guide band on piston provides low-friction guidance and support ASME/PED gas-over-oil pressure vessels complete with dipstick, hydraulic filter and adjustable speed controls High-pressure rated gas controls for local, remote and automatic operations Hydraulic manual override with four-position selector valve, purging port and breakdown-style pump lever If you need a different model other than those listed, please contact us at info@controlssupplychain.com.
