Diverting Valve

Three-Way Diverting Valves can be used for temperature

control in many heating and snowmelting applications.

Features

• Includes solder tailpieces (1-1/4" and 1-1/2" models use

same valve body with different tailpieces)

• Pre-installed high limit kit

• Compatible with most Viega actuators

Three Position - 18003

Proportional Acuator - 0-10v 18025

Non-electric Models - 16101, 16102, 16104,

16105, 16115

Speciﬁcations

Materials:

Bronze valve body

Brass and corrosion-resistant steel

internal components

EPDM rubber seals

Actuator threads: M30 x 1.0

Max working temp.: 242°F (120°C)

Max working pressure: 145 psi 10 bar)

Max differential pressure (tight shut-off on both end

positions of valve discs):

3/4" 10.9 psi (75 kPa)

1" 7.3 psi (50 kPa)

1-1/4" 2.9 psi (20 kPa)

1-1/2" 2.9 psi (20 kPa)

Operations

Diverting Valves have one entry port and two exit ports

(see diagram to the right). Depending upon the position of

the valve stem, ow is diverted from one exit port to the

other.

Product Instructions Installation The Diverting Valve is provided with a pre-installed temperature High Limit Kit. This kit is installed into the 3-way valve to allow a maximum supply water temperature to be set. This kit must be unscrewed when purging the system and should then be set according to the instructions below. Viega... The global leader in plumbing, heating and pipe joining systems 301 N.
