SAMSON Type 41-73 self-operated excess pressure regulator

Excess pressure valve, counterpart to Type 41-23. Opens when the upstream pressure rises and maintains the pressure in the line upstream of the valve. Design similar to 41-23: bellows stem seal and diaphragm actuator.

• No external energy sources
• Common components with 41-23
• Simple commissioning
