Drayton 22mm Motorised 3 Port Mid-Position Valve with Snap-On Actuator
Drayton 22mm Motorised 3 Port Mid-Position Valve & Snap-On Actuator (5 Wire SPST Switch) – MPN 27101 is a motorised 3-port mid-position valve designed for domestic Y-Plan central heating systems. It directs flow from a single common inlet to either heating, hot water, or both circuits simultaneously, using a 22mm compression brass valve body and a low-energy 230V snap-on actuator with 5-core wiring.
Key Features
- 3-port mid-position design – one common inlet and two outlets (A and B) to serve heating only, hot water only, or both at once.
- 22mm compression connections – standard domestic primary pipe size with easy-to-install compression fittings.
- Snap-on actuator – actuator can be released using a push-button and removed without draining the system, simplifying servicing and replacement.
- 5-wire SPST switching – supplied with 5-core cable and an integral switch suitable for standard Y-Plan wiring centres.
- Mid-position operation – capable of holding a central position to provide simultaneous flow to heating and hot water when demanded.
- Spring-return mechanism – spring returns the valve to a safe position on power loss, enhancing reliability and safety.
- Manual lever and position indicator – manual lever for override and system filling, with a clear visual indicator of valve position.
- Serviceable design – motor and complete actuator are replaceable, reducing long-term maintenance costs.
Technical Highlights
- Brand / Range: Drayton – Motorised Mid-Position Valve range.
- Model / Part: MA1/679-3 mid-position valve and actuator, Part No. 27101, SKU 6685.
- Valve type: 3-port mid-position (Y-Plan) zone valve.
- Connections: 22mm compression for copper tube.
- Valve body material: brass forging.
- Motor voltage / power: 230V AC, 50Hz, approximately 5W synchronous motor.
- Flow options: hot water only, heating only, or combined mid-position for both circuits.
- Maximum static pressure: 8.6 bar.
- Maximum differential pressure: up to around 0.7 bar.
- Water temperature range: 2°C to 93°C; maximum ambient temperature 52°C.
- Cable: approximately 1m, 5-core flex.
- Switch rating: typically 24–230V AC, 3(1)A.
- Approximate dimensions: height about 150mm, width around 124mm, depth about 70mm.
- Compliance: designed to meet EN 60730-1 and related automatic electrical control standards.
Typical Applications
- Y-Plan domestic heating systems providing independent and combined control of central heating and stored hot water from a single 3-port valve.
- Replacement for existing 22mm Drayton or compatible mid-position 3-port valves in conventional vented or sealed systems.
- Systems requiring flexible flow control with mid-position capability for improved comfort and energy efficiency.
Installation Notes
- Install the valve with the flow arrow in the correct direction and ensure the common port and A/B outlets are connected to the appropriate circuits, using clean, deburred pipework and correctly tightened compression joints.
- Fit or remove the snap-on actuator after pressure testing where possible, and always isolate mains power before any electrical or actuator work.
- Wire the valve using the standard Y-Plan 3-port valve 5-core diagram via a suitable wiring centre, interlocked with room and cylinder thermostats and the programmer/boiler.
- Locate the valve and actuator where the manual lever, cable entry and position indicator remain accessible for commissioning, servicing and fault-finding.
