ThisZL-2129ZL-2129 2 Way Motorised Zone Valve connects internal heating pipework by efficiently controlling the flow of water in iron and copper pipe systems. Specifically, it provides a highly durable and precise transfer of heating mediums, being designed for small bore central heating systems as well as commercial and industrial applications. Furthermore, thanks to its versatile design, you significantly speed up installation by easily plumbing the valve in at any angle above the horizontal level of the pipework.
Therefore, this 2 Way Motorised Zone Valve works perfectly for modern heating networks, handling demanding conditions with a maximum static pressure of 8.6 bar. Additionally, it effortlessly integrates into your system, safely operating with flow temperatures ranging from 5°C to 88°C.
The unit features a robust construction alongside a practical manual lever that can be moved from the ‘AUTO’ position to ‘MAN OPEN’ for system draindown and filling purposes. Moreover, the highly efficient 6W motor operates on a standard 230 Volts AC 50Hz power supply, featuring rapid timings of 12 seconds on under power and 6 seconds off under spring return. As a result, this reliable build makes it fully dependable for long-term installations, protecting your system with a maximum ambient temperature tolerance of 50°C.
Key Features & Benefits of 2 Way Zone Valve 22mm:
Reliable Flow Control: The valve is engineered to seamlessly control the flow of water in both iron and copper pipe systems. Consequently, it guarantees optimal performance for both residential small bore setups and demanding commercial applications.
Manual Override Lever: The system incorporates a convenient manual lever designed for temporary ‘MAN OPEN’ operation. Ultimately, this allows you to quickly and easily perform essential system draindown and filling tasks before returning the valve to the standard ‘AUTO’ position.
Fast & Efficient Motor: The unit operates with a nominal timing of 12 seconds under power to open, and a swift 6 seconds under spring return to close. For example, this provides highly responsive system automation with a minimal power consumption of just 6W.
Flexible Installation: The module allows for highly versatile mounting at almost any angle, provided the valve head remains above the horizontal pipework level to prevent safety hazards in the event of a leak. Besides that, it is compatible with standard 32mm or $1\frac{1}{4}^{\prime\prime}AF$ spanners for creating a secure, watertight compression seal.
High Pressure & Heat Stability: The motorised valve provides excellent structural integrity, withstanding a maximum static pressure of up to 8.6 bar. Importantly, it easily handles water flow temperatures from 5°C up to 88°C, making it exceptionally reliable for continuous daily heating cycles.
