What is a Proportional Pressure Regulator Valve?
In pneumatic world, a proportional pressure control valve is used to control downstream air pressure with an electronic signal. The input electronic signal is proportional to the span of the output pressure. For example, 0-10VDc of command signal corresponds to the output pressure span of 0 - 10 bar, with linear proportion relationship.

Type of Proportional Pressure Regulator Valve?
Kao Lu offers three types of electronic proportional pressure regulator: pressure ranges from vacuum -1~0bar, low pressure 0~2bar, 0~4bar, 0~8bar, medium pressure 0~16bar, 0~30bar, up to high pressure 0~70bar. In the high pressure control, the resolution can reach 0.5~0.6 bar.

Proportional Pressure Regulator Valve Working Principle?
Proportional Pressure Control Valve adopts a closed loop design and consists of two solenoid valves, an internal pressure sensor and an electronic control; according to an analog signal input, one solenoid valve is used to control the air intake and the other is used to control the pressure. Both valves work together to achieve a precise proportional pressure control. The proportional pressure regulator adopts two types of input signals: 0-10VDC or 4-20mA, and three types of monitor output signals: 1-5V, 0-10V or 4-20mA.
