The Drayton 22mm motorised zone valve represents a highly dependable solution for modern central heating systems that require precise hydraulic control. Engineered with a robust 230V actuator and a five-wire SPST switch configuration, it provides rapid automated zone isolation with an opening time of just 14 seconds. The unit is designed with a spring return mechanism ensuring a 100 percent tight shut off to prevent unwanted thermal transfer when the circuit is inactive.

Maintenance is considerably simplified by the inclusion of a highly intuitive Snap-On actuator. This innovative design allows heating engineers to remove the motor mechanism directly from the brass valve body by simply depressing a side-mounted release button. Such an arrangement enables rapid replacement of the actuator or motor components without the need to drain down the entire heating system, saving significant time during routine service visits. A clearly visible valve position indicator provides instant operational status feedback.

Q: What is the primary function of the side release button?
A: It allows the immediate detachment of the actuator head from the brass body for swift maintenance without system drainage.

Q: How quickly does the valve mechanism fully open?
A: The motorised actuator is designed to achieve a complete open position in exactly 14 seconds upon receiving a demand signal.

Q: Can the internal motor component be replaced independently?
A: Yes, both the entire actuator head and the internal motor are fully replaceable as separate individual components.

Q: Does the unit provide any visual confirmation of its current state?
A: A built-in valve indicator on the casing provides immediate visual confirmation of the current open or closed position.
