✔ 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
