Watts 0555177 Valve
Ensure transient surge protection and mitigate hydraulic shock in your commercial or residential piping systems with the Watts 0555177 Valve. This 1" LF600 lead free silent check valve is engineered for high-performance fluid control, featuring a Maxi-Flo conical disc designed to provide full flow with minimal pressure drop, comparable to a standard swing check but with silent closure. Constructed from a durable lead free cast copper silicon alloy, this 1 inch FNPT check valve is ideal for potable water, HVAC, and solar applications where lead-free compliance is mandatory.
The Watts LF600 series is designed for versatile field installation, functioning efficiently in either horizontal or vertical orientations (upward flow). With a robust 400 psi WOG non-shock pressure rating and a PTFE seat for positive shut-off, this valve effectively prevents backflow and water hammer in demanding industrial environments. The integrated stainless steel spring and guide rod ensure long-term mechanical reliability under fluctuating thermal conditions, ranging from -20°F to 100°F.
Key Benefits- Silent Operation: Eliminates water hammer and system noise during closure, protecting downstream components from shock.
- High Flow Efficiency: The conical lead free check design minimizes turbulence and maintains system head pressure.
- Versatile Mounting: Straight-pattern design allows for flexible positioning in tight mechanical rooms or riser stacks.
- Extreme Durability: Features a corrosion-resistant silicon alloy body and a PTFE seat for superior chemical and thermal resistance.
- Can this valve be used for steam applications? Yes, it is rated for 15 psi WSP at 250°F, making it suitable for low-pressure steam service.
- Is this valve a direct replacement for older Watts models? It is a direct lead-free alternative and replacement for the 0376354 series.
- Can it be installed with downward flow? No, for vertical installations, the flow must be in an upward direction to ensure the check functions properly.
