Solenoid Valves
Dual Acting Water Valve
Features
• Does the Work of Two Valves — The Model 265 handles
both the heating and cooling cycles of water source heat
pumps so that a separate valve for each cycle is unneces-
sary. As a result, cost is reduced, efficiency increased, and
maintenance simplified.
• Easy to adjust The conveniently located outer stem ad-
justs for heating, and an inner screw adjusts for cooling to
set valve opening points.
• Self-Cleaning
The Model 265 works well even in dirty water. The sliding
valve block wipes the orifice clean after every cycle. There-
fore, dirt can’t accumulate.
• Fights Corrosion Every part of the Model 265 that is
touched by water is stainless steel or brass. The sliding
block is Rulon
®
.
• Non-Chattering Operation is not affected by inlet pressure,
so there are no disturbing chattering sounds.
• Leak-Resistant The valve diaphragm has double seals to
prevent leakage.
