Watts 0123504 Check Valve

The Watts 0123504, part of the LFWCVS Series, is a heavy-duty 3/4 inch solder swing check valve engineered for critical backflow prevention in potable water and steam systems. Built with a lead-free brass body, this tee-pattern valve ensures compliance with strict low-lead safety standards for commercial and residential fluid control. Its robust construction features a metal-to-metal seat and a durable PTFE gasket, delivering a reliable seal that stands up to demanding cycles without the common degradation seen in plastic alternatives.

Designed for professional-grade integration, this valve offers solder end connections (sweat) for a secure, leak-free installation into copper piping. It is rated for a maximum pressure of 200 PSI WOG (non-shock) and 125 PSI WSP, providing a low pressure drop across the line to maintain system efficiency. This swing check mechanism allows for automatic closure when flow stops, protecting expensive pumps and boilers from the damaging effects of fluid reversal. For service technicians, the brass bonnet and pin assembly provide easy access for inspection in high-use HVAC and plumbing environments.

• Backflow Prevention: High-integrity swing check design stops reverse fluid flow in both hot and cold water applications.
• Lead-Free Construction: Complies with federal safety regulations for potable water systems, ensuring long-term code compliance.
• Metal-to-Metal Seating: Offers superior durability and heat resistance compared to rubber seals, perfect for steam and high-temp lines.
• Low Pressure Drop: Engineered internal geometry minimizes flow resistance to keep pump head requirements low.
• Secure Sweat Connections: 3/4" SW (Solder) ends provide the permanent, high-strength bond needed in pressurized mechanical systems.

• Can this valve be installed in a vertical orientation? Yes, this swing check valve can be installed in horizontal or vertical (up-flow) positions, provided indicate flow direction is maintained.
• Is the Watts 0123504 suitable for steam applications? Absolutely. With a 125 PSI WSP rating and metal-to-metal seals, it is specifically designed for steam and water service.
• Does this valve require regular maintenance? The lead-free brass construction and PTFE gasket are designed for longevity, though the top-entry bonnet allows for internal inspection if debris is suspected.
