This proportional control valve comes in sizes from 16 to 50mm and fits standard ISO 7368 and DIN 24342-cavity porting. Control areas provide 4 millisecond response time and can close the poppet under a high-pressure load. The valve has On Board Electronics. All you need to provide is a 0-10-volt command, which is proportionate to the position of the valve. No additional Amplifier Card is needed. The valve requires a 24-volt supply with a minimal electrical current of 3 amps per valve. It also requires a minimum pilot pressure of 40 psi. If voltage or pressure drops below the minimum requirement, the valve shifts closed to safe mode.
