[. . . ] They can be controlled by a line voltage SPST controller such as a room thermostat, aquastat or flow switch. The actuator head is removable without affecting the integrity of the water system. Features · Rugged design · Control by a line voltage SPST controller · Actuator head installation does not require draining of the system · High flow rate capacity · Indifferent to dirt in system Specifications Design V4044C-F-F and V4044F zone valves consist of: · 3-way valve housing with BSPP internal threads · Control ball assembly · Actuator assembly with cable · V4044F1000 with SPDT end switch · V4044F1034 with SPST end switch Medium Water or water-glycol mixture (max.

With the manual opener set to AUTO and the actuator energized, port A of the valve is opened and port B is closed. When the actuator is de-energized, a spring-return mechanism drives the ball to close port A, opening port B. Port A can also be opened with no electrical power by moving the manual opening lever over the stop and pushing slowly and firmly to the MAN. It is equipped with a 6-wire cable (line, neutral, earth, end switch NO, end switch NC) The length of all cables is 1m EN0H-0325GE25 R0906 2 Honeywell · All rights reserved V4044C-F-F, V4044F Dimensions Fig. Main dimensions and other values Body 1/2" BSPP (internal) 3/4" BSPP (internal) 1" BSPP (internal) 3/4" BSPP (internal) 1" BSPP (internal) kvs-value 3. 0 6. 0 8. 1 6. 0 8. 1 max. closeoff pressure 1. 4 bar 0. 7 bar 0. 55 bar 0. 7 bar 0. 55 bar Dimensions R 1/2" 3/4" 1" 3/4" 1" L 96 96 96 96 96 C 46 46 46 46 46 H 128 128 128 128 128 NOTE: All dimensions in mm if not otherwise stated Ordering Information Table 3.
