  • Angle body simplifies pipe routing

  • Bronze construction resists corrosion in heating systems
  • Rated for 60 psi water and 15 psi steam
  • Complies with ANSI B1.20.1 threading standard

Radiator Valve for Steam and Water Systems

This ZORO SELECT 109-305 radiator valve controls flow in hydronic heating installations using steam or water. It connects to 1-inch NPT pipe threads and features a bronze body built to ANSI B1.20.1 threading standards. The angle body style suits typical radiator connections and the hand wheel provides manual actuation.

Pressure Limits and Operational Scope

The valve handles a maximum water pressure of 60 psi and a maximum steam pressure of 15 psi. These ratings define the safe operating envelope for residential or light commercial heating loops. No electrical components or moving seals are described, so noise and power draw are not applicable to this mechanical device.

Installation Requirements and Build Integration

The 1-inch NPT male connection requires matching female threads on the supply piping and a 1-inch nut on the radiator side. The bronze construction resists corrosion in closed-loop water systems. Buyers needing a different pipe size, a straight body pattern, or automated actuator control will need a different valve model.

Highlights

  • Hand-wheel actuation allows manual flow control
  • Bronze construction resists corrosion in heating systems
  • Rated for 60 psi water and 15 psi steam
  • Complies with ANSI B1.20.1 threading standard

Questions about this item

How do I install the 1" NPT radiator valve and what step is often missed?

Thread the 1" NPT male end into the pipe using sealant rated for steam or water; the step often missed is tightening the 1" nut to the specified torque so the angle body seals at 60 psi water or 15 psi steam.

What maintenance or replacement will the bronze radiator valve need later?

Inspect the hand wheel and packing nut annually; replace the packing or the entire valve if leakage appears at the stem or if the bronze body shows corrosion after prolonged steam or water service.

What limit appears first under sustained use of the 1" NPT angle valve?

The 15 psi maximum steam pressure rating is the first limit reached during continuous steam operation; exceeding it risks seat damage and leaks before the 60 psi water pressure ceiling is approached.
