V4043 Motorised Zone Valve
APPLICATIONS
The V4043 valve has been designed to control the flow of
water in iron and copper pipe in diameters 1/2” to 1” and
15 mm to 28 mm.
Although specifically designed to control water flow in
small bore domestic central heating systems, the V4043
valve can be used in many other applications, e.g.
commercial and industrial heating systems.
• NORMALLY CLOSED VALVES:
V4043H — Has auxiliary switch. Used with domestic
central heating systems.
V4043C — Has high differential pressure close off. Used
with district heating systems.
• NORMALLY OPEN VALVE:
V4043B — Usually used in conjunction with solid fuel
boilers or dual fuel boiler link-ups.
• The V4043H forms part of SUNDIAL S & C PLANS used
to control domestic central heating systems and, as
such, is designed for quick, simple wiring either to a
T6160B or T6060B room thermostat, or a L641A
cylinder or pipe thermostat.
