PRODUCT DATA
APPLICATION
The Honeywell DS05C,D,G Dial-Set® Pressure Regulating
Valve is a high quality pressure regulating valve that maintains
a constant outlet pressure over a wide range of inlet supply
pressures. It is suitable for potable water and irrigation
applications. The downstream pressure adjustment dial
eliminates the need for a pressure gauge when adjusting the
pressure setting (static pressure only).

Water Capacities (See Table 1)
The suitability of a given regulator size is dependent on the
pressure requirements where it will operate. For the pressure
regulator valve size required for a specific installation,
determine the following:
1. Pressure differential between inlet and outlet pressure in
pounds per square inch (psi),
2. Capacity in gallons per minute, and
3. Allowable reduced pressure falloff in psi.
Table 1. Water Capacities.

Velocity in feet per second is based on schedule 40 pipe size. Recommended pressure falloff for general use is approximately
104 kPa (15 psi). Recommended velocities for the flow of water: residential and general use, 5 to 10 ft/sec; industrial use, 7 to 15
ft/sec; boiler feed, 7 to 15 ft/sec.
Given these variables, use Table 1 to determine the proper
size pressure regulator valve for your application.
Example: An installation has 135 psi inlet pressure, 60 psi
outlet pressure (75 psi pressure differential). If a 12 gpm
capacity is required with only 10 psi falloff allowable, a 1/2 in.
DS05 is required.
