General Installation
1. Install the regulator so that the flange connected
to the spring-loaded pilot’s feeding is in the
inlet side.
2. Use gaskets between pipeline and system flanges.
3. Connect the sensing line to the downstream.
Initial Verification
• PM unscrewed
• RM1 open
• RP1 open 3/4 turn
• R1, R2, R3, V1, V2 closed
Start up
1. Slowly open V1 (upstream valve).
2. Slowly open R1 and check the leakage of the pilot
nozzle PM by the absence of pressure rise on the
downstream pressure gauge.
3. Slowly open R2 and check the leakage of the
nozzle of the BPM1 by the absence of pressure
rise on the downstream pressure gauge.
4. Slowly open R3 and check the leakage of the
BPM2 by the absence of pressure rise on the
downstream pressure gauge.
5. Adjust PM to the required value Pd (read on M1 if
necessary using valve P1).
Maintenance
Disassembly
Check the absence of pressure between inlet and
outlet valves.
Recommended Frequency
Every year:
• Disassemble the manometric boxes and nozzles.
• Control O-rings, diaphragms, grease.
