The Reliance Valves (RWC) RV DZR Extended Lever Ball Valve is an essential tool for professional plumbers and HVAC technicians working with insulated pipework systems. Its primary benefit is the extended lever handle, which provides enough clearance to operate the valve without compressing, cutting, or damaging expensive thermal pipe insulation. While this design is highly efficient for insulated lines, it may require slightly more space in tight enclosures compared to standard short-handled ball valves.

This specific valve is designed for water and heating systems; always check local regulations and the product datasheet before using it for gas applications.
DZR stands for Dezincification Resistant, a type of brass alloy specifically formulated to prevent the leaching of zinc in corrosive water environments.
Yes, it is designed to provide a full-bore passage to ensure minimal resistance to flow.
The lever is designed to clear standard thickness pipe insulation; ensure there is at least 50mm of clearance around the valve area for ergonomic operation.
Yes, this ball valve is bidirectional and can be installed in either horizontal or vertical pipe runs without affecting its performance.
Apply a small amount of silicone-based lubricant to the spindle or operate the valve back and forth slowly to break up mineral deposits.
Gently tighten the gland nut behind the lever; do not overtighten, as this can cause the valve to seize.
Check the retaining nut holding the lever to the spindle and tighten with a spanner if necessary.
When installing the valve, ensure the piping is adequately supported to prevent mechanical stress on the valve body. Compatibility is key; verify that the pipe diameter matches the valve specification. Use appropriate thread sealants or PTFE tape compatible with the fluid medium (water or glycol-based mixtures). For care, operate the valve at least once every six months to prevent the buildup of scale or mineral deposits that could seize the ball mechanism over time. Periodically inspect the handle connection to ensure the nut remains tight and the lever moves freely through its 90-degree arc.
