Watts 0792077 Check Valve

The Watts 0792077 (Model LF7C) is a 3/8 inch dual check valve engineered to prevent the backflow of contaminated water into the potable water supply. This lead-free unit serves as the direct updated replacement for the discontinued 0061856 model, ensuring full compliance with NSF/ANSI 61 and NSF/ANSI 372 standards. Designed for continuous pressure applications, the LF7C features a compact, space-saving design with a chrome-plated brass body for superior corrosion resistance in high-use environments. The internal poppet-type check valves operate independently to provide reliable protection against backpressure and backsiphonage. With a maximum working pressure of 150 psi (10.3 bar) and a temperature range of 33°F to 180°F, this valve is ideal for carbonated beverage machines, lab equipment, and small-scale commercial plumbing setups. The 3/8 inch NPT female connections allow for a straightforward retrofit, minimizing downtime during field maintenance or system upgrades.

• Lead-free brass construction ensures compliance with safe drinking water regulations and provides long-term durability.
• Dual-check protection utilizes two independent check modules to prevent cross-contamination even if one seat fails.
• Compact footprint makes it the preferred choice for tight installations behind soda fountains or espresso machines.
• High temperature rating allows for reliable performance in hot water supply lines up to 180°F.
• Direct compatibility with discontinued Watts 0061856 units simplifies the replacement process for service contractors.

Is the Watts LF7C suitable for carbonated water systems?
Yes, the dual check valve for carbonators is specifically designed to handle the requirements of soda dispensing equipment, preventing CO2 from migrating back into the water main.

What is the difference between the 0792077 and the 0061856?
The 0792077 is the lead-free dual check valve successor. It maintains the same 3/8 inch NPT dimensions as the 0061856 but utilizes materials that meet current federal mandates for potable water safety.

Can this valve be installed in any orientation?
The LF7C is typically installed horizontally, but it can function in various positions. However, ensure the flow direction arrow on the body matches the system's water flow to prevent backflow preventer installation errors.
