Gas Valves by Port Size

Browse EN161-certified gas safety shut-off valves by connection size, from 1/4-inch to 2-inch BSP threaded models and DN65–DN300 flanged options. The range includes automatic-reset and manual-reset designs for burners, boilers and industrial gas systems, with supply voltages and operating pressure limits varying by model. Select the connection size alongside the required gas flow and allowable pressure loss. Confirm the valve’s approved gas types, maximum inlet pressure, reset function and any position feedback requirements. Our technical team can help you select a suitable valve for your installation.
