P37 | Gas Pressure Regulator
BelGAS Regulators
The BelGAS P37 Gas Pressure Regulator is a high-capacity, diaphragm-operated regulator designed for applications requiring stable pressure control at higher flow rates. Built with a balanced pintle design, it minimizes the effect of inlet pressure fluctuations to maintain consistent outlet pressure under varying conditions.
Designed for industrial compressed gas, natural gas, and propane systems, the P37 delivers strong flow performance while maintaining tight pressure control. Its non-relieving design and bubble-tight shutoff make it suitable for enclosed space applications where venting is not desired.
The regulator incorporates a Bellofram rolling diaphragm for improved sensitivity and responsiveness, along with a rugged construction that supports reliable operation in demanding environments. With flow capacity up to 110 SCFM, the P37 is well suited for higher volume gas delivery applications.
Typical Applications:
Pneumatic controllers, valve positioners, actuation systems, fuel gas supply, compressed air systems, and high flow gas distribution

PERFORMANCE ADVANTAGES
Why the P36 Performs Where It Counts
HIGH FLOW CAPABILITY
Delivers strong flow performance while maintaining stable outlet pressure, making it ideal for higher volume gas applications.
STABLE PRESSURE CONTROL
Balanced pintle design reduces the impact of inlet pressure changes, ensuring consistent downstream pressure.
SENSITIVE AND RESPONSIVE OPERATION
Bellofram rolling diaphragm improves responsiveness and control accuracy across varying operating conditions.
RELIABLE NON-RELIEVING DESIGN
Bubble-tight shutoff prevents gas venting, making it suitable for enclosed environments and controlled systems.
