Gas Pressure Regulator with Gauge Cellfast 52-501

Cellfast 52-501 is a gas pressure regulator with an integrated pressure gauge designed to reduce and stabilise inlet gas pressure for downstream appliances. It provides mechanical pressure control with a clear visual indicator for monitoring operating pressure. The unit is intended for installation in residential and light commercial gas systems where maintaining safe, consistent pressure to cookers, heaters or other gas appliances is required.

Advantages

The regulator combines pressure reduction and a built-in gauge in a single compact assembly, simplifying installation and ongoing checks. Mechanical regulation ensures steady, predictable output pressure without dependence on external power. The visible gauge allows fast verification of system pressure and aids troubleshooting, while robust construction supports reliable operation in typical domestic and light commercial environments.

Suitable for

• Domestic gas installations supplying cookers, boilers and space heaters
• Light commercial premises with low-to-medium flow gas appliances
• Replacement or upgrade of existing pressure control components in gas lines
• Applications requiring on-site visual monitoring of supply pressure

Key specifications

• Function: single-stage mechanical gas pressure regulation with integrated pressure gauge
• Connection type: threaded gas fittings suitable for standard pipework (check local compatibility)
• Pressure indication: analog dial gauge mounted on the regulator body for direct reading
• Intended use: designed for low- to medium-pressure distribution to household and light commercial appliances
• Construction: metal body and components engineered for gas system installation

How to use

Install the regulator in the gas supply line following local codes and the appliance manufacturer’s instructions. Ensure correct orientation and secure threaded connections with appropriate sealing materials rated for gas use. After installation, gradually open the supply and observe the integrated gauge while adjusting the regulator as required to obtain the desired downstream pressure. Verify there are no leaks at connections using an approved leak-detection method before placing appliances into service.

Usage recommendations

Have installation and adjustments performed or checked by a qualified gas technician. Use the gauge for routine checks of system pressure and schedule periodic inspections to confirm regulator integrity and safe operation. Replace the regulator if the gauge or control mechanism shows signs of malfunction, corrosion, or mechanical damage.
