Electro-proportional pilot-operated relief valve (740 Series) · 模型 51057
This 2-port, pilot-operated relief cartridge is an electro-proportionally controlled pressure regulating valve. Increasing current to the coil will proportionally increase the pressure setting. When the pressure at port 1 (inlet) is sufficient to overcome the solenoid force, as determined by the analog input signal, the poppet lifts and allows flow from port 1 to port 2 (outlet). Varying the analog input signal to the proportional solenoid provides a step-less control of pressure. For optimum performance, an amplifier with current sensing and adjustable dither should be used. Dither should be adjustable between 100 - 250 Hz. The W-range of this cartridge is designed to work with the 740 Series high-power coil, while the A-range utilizes the 740 Series low-power coil. All configurations of this valve include zinc-nickel plating as standard for 1000-hour salt fog protection. Coil connector options offer ratings up to IP69K. See individual coil product pages for details. The preferred mounting configuration is horizontal or vertically with the coil down. The valve can be mounted coil up if it is installed below reservoir oil level to prevent air accumulation in the solenoid tube. Do not actuate the valve manually or electrically when the valve is not installed. This valve is fully compatible with the XMD Expandable Mobile Drivers from Sun. Coils can be mounted on the tube in either direction. Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
