Watts 0067453 Valve

The Watts 0067453, commonly known by professionals as the RA-1-AP 1-1/4, is a heavy-duty steam radiator valve designed for isolation in two-pipe steam systems or various hydronic heating applications. Built with a rugged bronze body, this angle pattern valve features 1.25-inch FIP x male union connections, making it a drop-in replacement for standard residential and commercial cast iron radiators. The rising stem design and renewable composition disc ensure a positive shutoff, even in older systems with significant scale buildup. Each unit is engineered with Teflon stem packing to minimize maintenance and prevent leaks at the handwheel under pressure. For contractors managing steam balancing, this valve is rated for 15 psi saturated steam and up to 60 psi for water, providing the durability needed for the heating season.

• Angle pattern design allows for simplified vertical pipe alignment and compact connection to radiator inlets.
• Heavy-duty bronze construction provides superior corrosion resistance in high-moisture steam environments.
• 1.25-inch FIP x Male Union ensures compatibility with standard 1-1/4 steam radiator fittings.
• Rising stem and renewable disc allow for internal servicing without removing the entire valve body from the line.
• Teflon stem packing provides a reliable seal and smooth handwheel operation for years of use.

Is the Watts 0067453 compatible with one-pipe steam systems?
This valve is primarily intended for use as a shutoff on two-pipe steam or hydronic systems. In a one-pipe system, the valve must remain fully open during operation to allow condensate to drain against the flow of steam; it is not recommended for modulating heat in those configurations.

Can the internal components be replaced without unthreading the valve?
Yes, the RA-1-AP series features a renewable composition disc and a serviceable bonnet, allowing technicians to rebuild the valve seat or replace the disc during routine maintenance without disturbing the main piping.

What is the maximum pressure rating for this valve?
The valve is rated for a maximum working pressure of 15 psi for saturated steam and 60 psi for non-shock water applications.
