Watts 0555175 Valve
The Watts 0555175 is a 1/2" LF600 Maxiflo Lead Free Silent Check Valve engineered for commercial, industrial, and residential hydronic systems where preventing water hammer is critical. Constructed from a durable lead-free cast copper silicon alloy, this valve ensures code compliance for potable water and steam applications. The conical brass disc and PTFE seat provide a positive seal with minimal back-check, while the stainless steel spring and guide rod maintain consistent performance under high-flow conditions. Designed for versatility, the LF600 series supports both vertical (upward flow) and horizontal installations, offering a low pressure drop comparable to traditional swing check valves. With a 400 PSI WOG non-shock rating and a 15 PSI WSP steam rating, this 1/2 inch FNPT check valve provides reliable backflow prevention and silent operation. The compact 2-1/8" inlet-to-outlet length makes it an ideal drop-in replacement for tight mechanical rooms and piping manifolds.
Key Benefits:- Water Hammer Mitigation: Silent operation eliminates the damaging noise and vibration caused by fluid surges in HVACR and plumbing lines.
- Lead-Free Compliance: Manufactured with lead-free brass alloy to meet NSF/ANSI 372 and safe drinking water standards.
- Installation Flexibility: Can be mounted in horizontal or vertical positions to accommodate various piping configurations.
- High Pressure Resilience: Rated for up to 400 PSI, making it suitable for demanding industrial utility systems.
- Durable Sealing: Features a PTFE seat for superior chemical resistance and long-term sealing integrity.
Can I use this valve for steam service?
Yes, the Watts 0555175 is rated for 15 PSI WSP at temperatures up to 250 degrees Fahrenheit.
Does this valve require a specific orientation?
The Watts LF600 can be installed horizontally or vertically, provided the flow is in the upward direction for vertical runs to ensure the conical disc seats correctly.
Is this a direct replacement for the LF600 1/2" series?
Yes, the 0555175 is the standard ordering code for the 1/2" threaded Maxiflo silent check valve.
