94A and 94ALF-A Lead Free Forged Brass Ball Valves

Most customers will never experience an issue with their Apollo valves. The few reports we do receive

related to body joint, stem packing or seat leaks involve solder valves rather than NPT, so heat

definitely plays a role. Limiting the amount of heat applied beyond the solder cup will prevent most

problems.

1. Always identify the alloy to be soldered. 94ALF EZ-Solder

contain silicon alloy, meaning heat transfer rates are identical to standard brass. Therefore

extra

heat

Note also that brass conducts heat at a rate 50% faster than bronze, so brass valves in general

require less heating time than comparable bronze valves.

2. Always review the applicable Apollo Installation, Operation & Maintenance Instructions to

ensure factory recommendations are being followed:

3. We also recommend viewing our Apollo soldering video and the Copper Development

Association-produced video entitled Soldering of No Lead...Valves. Both cover Industry

Best Practices relative to soldering valves. We particularly endorse heating of the tube prior

to heating the solder cup of the valve to reduce the total amount of heat applied to the valve.

4. The installer should be mindful of the type of gas being used. Acetylene is the hottest industrial

gas, meaning it requires the most care and caution when soldering vs MAPP gas or propane.

Always move the flame to evenly distribute the heat to all surfaces of the solder cup during

heating.

5. Do NOT oversize the torch tip! The torch tip selection should be appropriate for the pipe size,

based on the torch manufacturers' recommendation (see example below). In fact TurboTorch

technicians advise their tip sizing chart is based on wrot copper fittings, and they recommend

reducing the tip selection by 1 – 2 sizes when soldering (ball) valves due to the PTFE

components.
