Secure Zoneplus Z322 22mm 3 Port Mid-Position Motorised Valve

Product description

• 3 Port Diverter : Efficiently manages water flow between central heating and hot water cylinders in a Y-plan system.
• 22mm Compression : Standard 22mm fittings allow for easy installation into existing copper pipework.
• Mid-Position Operation : Allows for heating only, hot water only, or both simultaneously for flexible control.
• Reliable Actuator : Features a robust motor head with a spring-return mechanism for consistent performance.
• Manual Lever : Includes a manual lever for filling and draining the system easily during maintenance.
• Standard Replacement : An ideal replacement unit for existing 3-port mid-position valves in domestic systems.

• 3 port mid-position valve: Diverts flow to hot water, central heating or both at once, for fully pumped Y-plan systems that use a single pump
• 22mm compression: Brass valve body supplied with 22mm compression fittings for straightforward connection to standard copper pipework
• Replaceable actuator: The A322 actuator head can be changed separately from the B322 valve body, making future servicing quicker
• Hansen Synchron motor: Class F Synchron motor with spring return, opening in up to 20 seconds and closing in up to 10 seconds
• Manual override lever: Holds the valve in mid-position for filling and draining the system, then returns to auto for normal running
• Ready to wire: Industry standard colour-coded 1.4m cable, 230V 50Hz supply, 5W consumption and 3A 250V AC switch rating

The Secure Zoneplus Z322 is a 22mm three port mid-position diverter valve for domestic central heating systems with a single pump for both the heating and hot water circuits, the layout usually called a Y-plan. Controlled by your programmer and thermostats, it sends flow to hot water, heating, or both at once from its middle position. The A322 actuator and brass B322 body are sold separately as spares, so a failed head can be swapped without replacing the body. A manual lever holds the valve open in the mid-position while the system is filled or drained; it must be returned to auto for normal operation. Specification: 22mm compression fittings supplied, 230V 50Hz, 5W power consumption, 3A 250V AC contact rating, 1.4m industry standard cable, maximum static pressure 8.6 bar, maximum differential pressure 0.5 bar, brass body with EPDM ball and thermoplastic cover. In the box: Z322 valve, 22mm compression fittings and instructions. Made by Secure (formerly Horstmann), 2 year warranty. Check whether your system needs a 2 port or 3 port valve before ordering; for a single 2 port zone see the Secure Z222.
