Frequently asked questions
Common questions about Watts Pressure Relief Valve from 3G Electric.
How do I size a Watts pressure relief valve?
Match the valve's rated relieving capacity to the boiler, heater or system input, then select set pressure at or below the equipment's maximum allowable working pressure. Check ASME code section, inlet size and connection type against your installation before ordering.
What is the difference between ASME Section IV and Section XIII Watts valves?
ASME Section IV valves are for heating boilers and hot water supply systems, while Section XIII covers temperature and pressure relief on hot water heaters and similar equipment. Non-code Watts relief valves suit air, inert gas and liquid circuits where ASME stamping is not required.
Does 3G Electric ship Watts pressure relief valves worldwide?
Yes. 3G Electric supplies Watts pressure relief valves and backflow preventers worldwide from our 386-item catalog, covering ASME safety valves, regulators and dual check assemblies. Share your set pressure, capacity and connection details and we will confirm availability and lead time.
