Coil Control Valve
Chilled water, hot water and steam coils accommodate control valves when selecting options
8,9,G,H,Q,R,T,U,V,W and Z for DIGITS 16 and 17. The control valves are available as a three-point modu-
lating arrangement. The control valve option includes the following:
Threaded connections on both the 2-way and 3-way configurations;
1/2-and 3/4-inch nominal sizing for both the 2-way and 3-way configurations;
Valve motor leads to include an 18-gauge wire, 6-inches in length, with internal strain relief;
2 1/2-inch clearance above cover required for cover removal
