Electro-proportional relief valve - high pressure setting with no command · 模型 51059
This 2-port, pilot-operated relief cartridge is an electro-proportionally controlled, normally-closed pressure regulating valve. The valve is spring biased closed to its highest setting (customer specified). Increasing current to the coil will proportionally decrease the pressure setting. When the pressure at port 1 (inlet) is sufficient to overcome the spring force minus the solenoid force, as determined by the analog input signal, the poppet lifts and allows flow from port 1 to port 2 (outlet). The setting represents the maximum relief pressure which the valve will default to with no command. As the command increases, the relief setting will decrease. See performance curves for selected pressure range. Varying the analog input signal to the proportional solenoid provides a step-less control of pressure. Damped construction provides stable operation over a wide range of operating conditions. For optimum performance, an amplifier with current sensing and adjustable dither should be used. Dither should be adjustable between 100 - 250 Hz. This cartridge utilizes 740 Series low-power and high-power coils, and 747 Series hazardous location coils. 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. This valve is fully compatible with the XMD Expandable Mobile Drivers from Sun. 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. 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.
