Proportional flow valve 3FREEZ-1X is a high-precision fluid control component, which is usually used in industrial automation systems that require precise flow regulation or flow ratio distribution. Valve 3FREEZ-1X is an electronically controlled proportional regulator (0-10V/4-20mA signal input). The pressure can usually reach 315Bar, suitable for high-pressure hydraulic systems. Proportional flow valve 3FREEZ-1X valve can be integrated with PLC and DCS systems and supports MODBUS and other communication protocols. The proportional valve 3FREEZ-1X controls the flow rate through the proportion of electrical signals, realizes stepless speed regulation of the actuator, and improves the response accuracy of the system.

Application:
Proportional flow valve 3FREEZ-1X is widely used in hydraulic systems, construction machinery, injection molding machines, die-casting machines, chemical/process control, etc. The explosion-proof model can also be used in automation equipment in hazardous areas such as oil and natural gas.
General
Type 3FREEZ proportional flow control valves with position control and on-board electronics are available in nominal sizes6 and 10. They are actuated by means of a proportional solenoid with inductive position transducer. Hysteresis is < 1 %.
The on-board electronics are calibrated at the factory and enable rapid response times. The design of the valve body is such that the residual flow runs through port P.
Basic principle
To adjust the oil flow rate from B, a setpoint is set in the trigger electronics. Based on this setpoint, the electronics control the solenoid coil as a function of the signal from the position transducer. The position control ensures very low hysteresis. The valve opening is determined by the metering edges on the spool, and the integrated pressure compensator compares the pressure drop by means of an 8-bar measuring spring. The pressure compensator with measuring spring regulates the pressure before the throttling edge according to the simplified formula: "Load pressure plus force of measuring spring”. In this way, the pressure drop over the metering edge is maintained at a constant level.
