Value Brand 109-314 Steam Radiator Valve 3/4 in NPT Forged Brass

SKU CH-AYMN-HCNHF

Controls steam or water flow in radiators with a 3/4 in NPT forged brass body rated to 60 psi water and 15 psi steam

  • Forged brass body resists corrosion and wear
  • Angle body style fits tight piping layouts
  • NPT threads seal steam and water lines
  • 15 psi steam and 60 psi water ratings cover typical heating systems
  • ANSI B1.20.1 compliance ensures thread compatibility

Steam Radiator Valve 3/4 in NPT

The Value Brand 109-314 is a forged brass angle valve designed for steam and water heating systems. It suits installers and maintenance teams needing a reliable shut-off for standard 3/4 inch NPT pipe connections. The hand wheel actuation provides direct manual control. This component meets ANSI B 1.20.1 threading standards for compatibility.

15 psi Maximum Steam Pressure

The single specification that decides fit is the maximum steam pressure rating of 15 psi. Systems operating above this limit require a different valve to maintain safety and seal integrity. The water pressure rating reaches 60 psi for hydronic applications. Verify your system pressure before installation to ensure correct selection.

Sustained Pressure Performance

Under continuous steam service the forged brass body resists deformation at the rated 15 psi limit. The angle body style promotes drainage and reduces water hammer during prolonged cycling. The hand wheel maintains positive shut-off without the drift sometimes seen in spring-loaded designs over long heating seasons. California Proposition 65 warnings apply to this product.

Questions about this item

What does the 15 psi steam pressure limit mean for my heating system?

It means this valve is rated for low-pressure steam boilers only; do not use it on systems that operate above 15 psi steam pressure.

How does the NPT thread standard affect installation?

The 3/4 in NPT threads follow ANSI B1.20.1 taper, so they seal with thread sealant and require a matching NPT fitting — not a straight thread or compression joint.

What clearance does the angle body and hand wheel need?

The angle pattern changes flow direction and the hand wheel sits on top, so you need room above and beside the inlet for the wheel to turn freely.
