The Honeywell 3278 series 1" two position normally closed zone valve is a fully welded, low lead brass constructed valve. The three 5/8" male pipe fittings are for a lead or copper water supply line between the zone valve and water meter or similar pressure reducing equipment and reduced to a 2½" connection to the sprinkler system. The diaphragm has been test certified to 100 psi @ 75°F (24.4 Bar @ 24°C) operating pressure.

The Honeywell 3278 Zone Valve is a 24 VDC, normally closed valve that accepts up to 3.5 cm (1-1/4") supply piping. This valve is self-contained and 2-position versions have a handle that must be positioned manually in the second operating po

Zone valve delivers two on/off positions to control water flow in a piping system and is installed in an open piping loop. Its N/C (normally closed) poppet provides isolation from water supply, while the trigger position opens the inlet port for complete flow through the system. Valve can be manually or electrically actuated.

The 3-Way Valve is a One-Inch, normally closed two-position zone valve which is direct-operated and normally open with a spring energized actuator. The 3-Way Valve can be used to control hot or cold water, or steam, in many commercial and residential applications.
