Watts 0794151 Valve Kit

Watts 0794151 Valve Kit

The Watts 0794151 (LFRK 909-VT) is a comprehensive factory relief valve repair kit engineered for 4" to 10" Reduced Pressure Zone (RPZ) backflow assemblies. Designed specifically for the Watts Series 909 and LF909, this total relief valve kit provides everything a technician needs to restore the integrity of the hydraulic zone between the check valves. The kit ensures lead-free compliance and is built to withstand the high-torque environments of commercial and municipal water systems. By utilizing original equipment manufacturer (OEM) components, you ensure backflow preventer maintenance meets strict field performance standards, eliminating the risks associated with non-standardized aftermarket parts.

This LFRK 909-VT 4-10" kit allows for in-line serviceability without the need for specialty tools, facilitating efficient repairs of the 909 M1 series relief valve. Whether you are dealing with a 909 4-6 inch or the 909M1 8-10 inch unit, the included diaphragm, piston assembly, and seat are precision-machined for a drop-in fit. To prevent shaft damage, always ensure the cover is perfectly aligned before tightening bolts; the 909's unique design retains the spring load under the bottom plug for safer disassembly.

  • Broad Compatibility: Fits 4", 6", 8", and 10" Watts 909/LF909/909M1 series assemblies.
  • Complete Assembly: Includes diaphragm, disc and piston assembly, seat, seat O-ring, adapter O-ring, and high-grade lubricant.
  • Lead-Free Construction: Complies with low-lead regulations for potable water applications.
  • Durable Performance: Uses high-quality elastomeric and metallic components for extended duty cycles in rigorous commercial environments.
  • Optimized Drainage: Restores original discharge capacity during emergency backpressure or backsiphonage conditions.

Common Questions

Does this kit work for both the 909 and the lead-free LF909 models?
Yes, the 0794151 repair kit is fully compatible with both the standard 909 and the Lead Free LF909 versions, as the internal relief valve dimensions remain consistent across both lines.

Can I install this kit while the backflow preventer is still in the piping?
Yes, this kit is specifically designed for in-line repairs. However, the system must be depressurized and the upstream/downstream shutoff valves must be closed before beginning work.

What is the difference between the 'Rubber Parts Kit' and this 'Total Relief Valve Kit'?
The Rubber Parts Kit (RK-RV) only provides the elastomers, whereas this Total Kit (RK-VT) includes the hard parts such as the seat and the entire disc/piston assembly, which is necessary if the internal mechanical components are pitted or worn.
