Body material: Cast iron HF
Connection: Flanged
The ASTA P03 series control valves are designed to regulate the flow of the working medium by changing the flow area of the valve.
The angular valve body provides a higher flow rate and has a lower pressure loss at high flow rates, and is also minimally susceptible to cavitation damage.
The valves have a wide range of applications depending on the type of control pilot.
