DS05 DIAL SET PRESSURE REGULATING VALVE

TROUBLESHOOTING

Table 2 provides a troubleshooting guide for the DS05 Dial Set Pressure Regulating Valve.

Table 2. Troubleshooting the DS05 Dial Set Pressure Regulating Valve.

Problem

Solution

Whistling noise.

•

Slightly increase or decrease the outlet pressure until the noise disappears.

Will not hold pressure.

•

Clean the filter cartridge as described in the Installation section.

Chatters.

•

Replace the screen and O-rings.

•

Replace the cartridge as shown in Fig. 3.

Freezes up.

•

Replace bonnet or cartridge if damaged.

•

To avoid future freeze-up:

— Temporarily (slightly) open a downstream faucet if the DS05 will be exposed

to temperatures below 32°F (0°C). The slight water flow will eliminate
freeze-up.  

— Move the DS05 to a location with an ambient temperature above 32°F (0°C)

If it is currently exposed to prolonged temperatures below 32°F (0°C).

Pressure gauge measures a lower
pressure under flow conditions than
was originally set during static
conditions.

•

DS05 is functioning properly. No action is necessary. The pressure decrease is
characteristic of all direct acting pressure regulating valves and is referred to as
falloff.
