Value Brand 109-303 Radiator Valve 1/2 In
Bronze angle radiator valve with 1/2 in NPT connections for steam or water systems up to 60 psi
- Bronze body resists corrosion for long service life
- Angle body style simplifies piping in tight spaces
- 1/2 in NPT connections fit standard steam and water lines
- 15 psi steam and 60 psi water ratings cover typical heating systems
- Hand-wheel nut actuation gives precise manual control
Right fit for 1/2 in NPT steam radiators
This angle-pattern radiator valve connects 1/2 in NPT pipework to a matching 1/2 in radiator union. It is built for steam or hot-water heating systems and uses a bronze body with a hand-wheel actuator. Buyers who need a different pipe size, a straight body or an automated actuator should look elsewhere.
Rated 15 psi steam and 60 psi water pressure
The valve handles up to 15 psi steam pressure and 60 psi water pressure, meeting ANSI B1.20.1 thread standards. Selecting this part without confirming the system stays within those limits risks leaks or premature failure.
Hand-wheel operation on bronze angle body
Installation requires threading the 1/2 in NPT connections and tightening the union nut by hand or with a wrench. Common issues include cross-threading the tapered threads, over-tightening the bronze body, or forgetting to verify the system pressure stays below the 15 psi steam rating.

Questions about this item
What does the 15 psi steam rating mean once the valve is installed?
It means the valve is tested to handle up to 15 psi of steam pressure in the radiator circuit; systems running higher steam pressure need a different valve.
How does the NPT thread standard affect what pipe I can connect?
The 1/2 inch NPT threads accept standard 1/2 inch NPT pipe or fittings; mismatched thread types will not seal.
What clearance does the angle body style need at the radiator?
The angle body turns the flow from horizontal pipe to vertical radiator inlet, so allow space for the valve body and hand wheel to clear the radiator side.
