Drayton zone valve actuator manual

The only important thing to observe is that the valve must not be mounted so that the valve head the metal box you can see below with the danger sign on it is below the horizontal level of the pipework, as in the unlikely event of a leak, a safety hazard could result. The new Honeywell Zone Valves now in position.

So with all that done, it was simply a matter of refilling the heating system — as to how to do which, you might like to check out my earlier blog on how to bleed a radiator. With baited breath I then pressed the Heating button on the programmer…. Job done, and I have to say, an enormous sense of satisfaction at having solved a problem that a few days earlier had me scratching my head in confusion.

Potentially repairable with superglue, but decided not to risk it, although its a very expensive solution to deal with a bit of broken plastic. Poor design by manufacturer. Is this compatible with a drayton ZA6 dual zone actuator? The ZA5 can be used to replace a ZA6 if the white wire is not being used.

Answered by: Martin, Technical Support. Is this a suitable replacement for a Drayton Hansen class F diverted valve? I'm sorry but we don't recognise that part number are you able to send us a photo please, Answered by: Martin, Technical Support. Is this a suitable replacement for the Drayton ZA5 valve actuator? If you have an older bolt on type of actuator, you will need to swap out both the actuator and valve body. An actuator is a device that uses a form of power to convert a control signal into mechanical motion.

From electric door locks in automobiles, to ailerons on aircraft, actuators are all around us. They work by powering a motor against a spring, for one position full power is provided to open one port fully; for mid position the power is reduced to the motor via a resistor which means near the mid point the motor stalls.

A valve actuator is the mechanism for opening and closing a valve. Manually operated valves require someone in attendance to adjust them using a direct or geared mechanism attached to the valve stem.

A diverter valve works by opening and closing to allow or restrict the hot water that travels to your radiators or taps. When your combi boiler needs to send hot water to a tap instead of the radiators, the relevant diverter valve will close.

All the heads are attached to a single head actuator , also called an actuator arm, that moves the heads around the platters. Older hard drives used a stepper motor actuator , which moved the heads based on a motor reacting to stepper pulses.

In all cases, when the zone valve is fully open, an "end switch" inside the valve tells the heating system's circulator to begin operating, causing hot water to flow through the zone.

A 3 - way zone valve is a bypass version of a 2- way zone valve with 3 ports, commonly used with fan coils, heating units or other central heating equipment. When it is required to bypass the equipment, the supply port of the valve is closed automatically or manually and the water flows though the bypass port. The valve's actuator can be installed after the valve body has been installed onto the fan coil, baseboard or air handler.

VS Series valves are available for low pressure steam applications. PopTop Series are two position spring return valves. Actuators are designed fror cycling applications not constantly powered. You'll need one for each zone. They control the flow of water or steam to each area of your home. Troubleshooting Hot Water Zone Valves. End switches in each zone valve control the central circulator and the burner.

On a call for heat, the valve is opened. It controls the flow of water in a room or zone in response to the demands of the room or zone thermostat.
