The Cool Energy ZVD28 Motorised Zone Valve is purposefully engineered as a three‑port diverter valve that directs hot water flow between central heating circuits and cylinder circuits in pumped systems, helping prioritise where heat is needed most. With a 28 mm compression body in robust brass and a 230 V motor with spring‑return action, it offers dependable operation and a manual override for filling or maintenance. Designed for reliable service with industry‑standard wiring and a compact profile, it brings straightforward, precise flow control to domestic heating installations.

You then have a further 14 days to return the item. Goods should be returned in their original condition and packaging. Returned items will be inspected and, where an item has been used, installed, damaged or handled beyond what is reasonably necessary, resulting in a reduction in value or resaleability, we reserve the right to make an appropriate deduction from the refund to reflect that loss in value, up to the full purchase price. Any refund due will be issued within 14 days. Rejected deliveries or failed delivery attempts may be treated as change-of-mind returns. Return postage for change-of-mind returns is at your own cost.

✔ 3-Port Spring Return Configuration — Selective Priority Zone Control — The ZVD spring return valve provides 3-port diverting control specifically engineered for domestic central heating systems where both the radiator and hot water cylinder circuits operate on a pumped, selective priority basis — ensuring correct hydraulic sequencing between competing heat demands.

✔ Spring Return Actuation — Fail-Safe Default Position — The spring return mechanism automatically returns the valve to its default port position on power loss, providing inherent fail-safe operation that protects system components and maintains a defined circuit state under all operating conditions.

✔ 230Vac Operation — Standard Mains Voltage Compatibility — Operates on a 230Vac supply for direct compatibility with standard domestic control wiring configurations, eliminating the need for additional transformers or voltage conversion within the control circuit.

✔ 6W Power Consumption — Minimal Parasitic Load — A 6W operating power draw places a negligible parasitic load on the electrical system, contributing no meaningful addition to system running costs throughout continuous operational use.

✔ +5°C to +88°C Fluid Temperature Range — Full Heating and Domestic Hot Water Circuit Compatibility — The operational fluid temperature envelope of +5°C to +88°C covers the full range of domestic heating flow temperatures and unvented cylinder primary circuit conditions without thermal limitation.

✔ +52°C Maximum Ambient Temperature — Plant Room and Airing Cupboard Rated — Rated for continuous operation in ambient temperatures up to +52°C, ensuring reliable performance in enclosed plant rooms, airing cupboards, and other thermally elevated installation environments.

✔ 1 Metre 5-Core Cable — Standard Control Wiring Interface — Supplied with a 1 metre 5-core cable providing the full conductor complement required for standard zone valve wiring configurations, supporting direct connection to programmers, thermostats, and system controls without additional cable or junction requirements.

✔ 1 x Motorised Zone Valve
