The Honeywell Braukmann DS05 Dial Set Pressure
LOCKING SCREW
Regulating Valve is a balanced, direct acting pressure
regulating valve. The DS05 provides constant downstream
ADJUSTING
pressure regardless of varying inlet pressures and
KNOB
downstream flow demands.
DIAL RING
The spring force holds the valve in the open position until
downstream pressure, sensed by a port, is sufficient to press
on the underside of the diaphragm and close the valve. As
downstream pressure drops due to demand, the force on the
diaphragm is reduced and the valve opens. Adjustment is
BONNET
made by manually turning the adjustment knob clockwise
downstream pressure to close the valve. Similarly, reducing
the spring force lowers the outlet set pressure. A factory-
calibrated dial is built into the adjustment mechanism to allow
outlet pressure (no flow) to be set without a gauge. A locking
screw maintains the setting. A black plastic cover is provided
to conceal the setting and protect the DialSet from moisture
SPINDLE
and debris.
Once the outlet pressure is set, the DS05 automatically
SPRING
regulates to maintain the downstream pressure. See Fig. 5 for
the internal construction of the DS05.
WASHER NOTE: Minimum ambient rating is 33°F (1°C).
