Head-Pressure Control Valves Installation

To ensure the proper execution, pressure-control valves must be selected and applied correctly. These valves can be installed in a horizontal or vertical line. if possible, the valves should be oriented so the solder cannot run in the internal details during the soldering process. Care should be taken to install valves with flow in the right direction. ARI and ORO valves can be installed in the discharge line and for any reason.

In most cases, the valves are located in the condensing unit. When the capacitor is remote from the compressor, in the usual place, near the compressor. In all cases, it is important that some precautions when installing the valve. While heavy valve is approximately 2.5 pounds (1.14 kg) of weight, it is assumed that they will receive sufficient support to prevent excessive stress on the joints. Because the output line of the possible source of vibrations, which are a result of the discharge gas pulses and forces of inertia associated with moving parts, fatigue pipes, fittings and connections may result. Ripple best solved by placing a good silencer as close as possible to the compressor as possible.

Vibration from the moving parts of the compressor better insulated flexible loops or coils (reset lines or less) or flexible metal hoses for big lines. For best results, hoses should be installed as close as possible to the compressor shut-off valves as possible. Hoses must be mounted horizontally and parallel to the crankshaft or vertically. Hoses should never be installed horizontally and 90 from the crankshaft. Hard bandage should be made at the output end of the hose. This bracket will prevent oscillations at the tube.
