The ASTA P02 series control valves are designed to regulate the flow of the working medium by changing the flow cross-section of the valve.
The force created by the working medium is supplied to the actuator through impulse tubes, acts on the actuator membrane and the valve spring, thereby setting the stem in motion.
The valves have a wide range of applications depending on the type of control pilot.
