Watts 0792012 Breaker
The Watts 0792012 (Model 1" LF800M4-QT) is a contractor-grade lead free pressure vacuum breaker engineered for high-hazard continuous pressure applications. Designed specifically for irrigation systems and industrial process water lines, this backflow preventer features a lead-free cast copper silicon alloy body to ensure compliance with potable water regulations. The Watts LF800M4-QT utilizes a unique acetal bonnet that doubles as a freeze plug, mitigating expensive damage to the main valve body during unexpected temperature drops. Maintenance is streamlined via quarter-turn ball valve shutoffs and accessible test cocks, allowing for efficient winterization and field testing. With a maximum working pressure of 150 PSI and a temperature range of 33°F to 140°F, this unit provides robust backsiphonage protection in compact spaces. The assembly includes silicone rubber check valve discs and stainless steel springs, ensuring long-term seat integrity and reliable performance under varied flow conditions.
Key Benefits- Lead-Free Design: Cast copper silicon alloy construction meets all federal regulations for potable water safety.
- Freeze Protection: Integrated acetal bonnet acts as a sacrificial freeze plug to prevent catastrophic body failure.
- Serviceability: Replaceable plastic seat and easy-access internal components allow for quick repairs without professional tools.
- Versatile Application: Rated for health hazard continuous pressure, making it ideal for large-scale irrigation and commercial processing.
- Compact Profile: Space-saving configuration fits into tight service enclosures or manifold setups.
- Can this unit be installed in high-backpressure applications? No, this is a pressure vacuum breaker (PVB) designed for backsiphonage only; it must be installed at least 12 inches above the highest downstream point and never where backpressure is present.
- How do I prepare this valve for winter? Use the test cocks to drain the internal chambers and leave the quarter-turn handles at a 45-degree angle to prevent trapped water from cracking the ball valves.
- Is this compatible with the 800M2 series? Yes, the LF800M4-QT typically shares the same lay-length and dimensions as older 800M2 models, allowing for direct replacement in most piping configurations.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
