They contain synchronous motor which develop full rated torque almost instantaneously with the turning on of power supply and requires no additional braking assembly when surmounted on butterfly valves or dampers. Moreover, their polymer housing make them the best choice for corrosive environments. They are housed in die cast aluminum and assimilate features like declutch-able manual hand-wheel overrides, local remote switching stations and a multitude of speed, voltage and torque ratings..Radius is a leader in manufacturing and supplying valve actuators and accessories. Radius manufactures series EW electric actuators manufactured are rugged worm gear driven actuators which are best suited for stringent valve regulation. In the actuator segment, the company has high quality pneumatic, electric, electro-hydraulic and scotch Pipe Fittings Caps Suppliers https://www.bdsjfm.com/product/pipe-fittings/cap/ yoke actuators. These actuators are widely used in different types of industries for safety and control purposes.The Electro-Hydraulic Spring Return actuators from Radius are specifically designed quarter turn valve and damper applications.Radius also manufactures series K Scotch yoke actuators are available in carbon steel yoke mechanism and particularly designed for use with quarter-turn valves. They use hydraulic spring return actuators assembled with compact hydraulic unit. A Large output torque range is delivered by their large radii which ensure the actuators match the operational characteristics of plug, ball or butterfly valves or any other device which require accurate and reliable 90° rotary motion. The rugged Swiss extruded bodies of these actuators coupled with the hard anodized pistons make them a bench mark in rack and pinion actuators. These actuators offer unparallel performance and set high standards of safety and reliability.In the pneumatic actuator segment, Radius produces series A dual acting and spring return pneumatic valve actuator. On supplying electric power, the control box opens a pilot valve which in turn signals the pump to deliver hydraulic fluid to the actuator, which opens the valve. Standard features like double travel stops and internal/external corrosion protection are also provided in these pneumatic ball valve actuators and that too at a very economical price. The company is based in Milford, Michigan and deals in several types of actuators and valves. Series ER electric valve actuators are more suitable for running quarter turn valve applications.
