Function principle:
First, set a certain air pressure for the S1 port, then the air pressure of S2 port will change from time to time;
when (S1-S2)>0.1bar, the port A will open, the angle seat valve will be opened;
when (S2-S1)>0.1bar, the port A will close, the angle seat valve will be closed by spring force;
Advantages:
Automaticly adjusting and working, no other people or device needed
High sensitivity: the pressure change to +/-0.1bar, balancing
valve will auto switch
Techincal data:
Port Size:
P,A: G1/4", S1, S2: G1/8"
Pressure range:
S1 port: certain pressure, 0.2-4bar, you can set it on your request
S2 port: sampling pressure from equipment pipelines, will be in range S1+/-0.1bar
P,A port: according to the control pressure of the connected
angle seat valve, normally 2-8bar
Temperature range: 0-100°C
