The LavaTap - Drayton 27100 is a professional-grade drayton 2 port motorised valve specifically engineered for the high-precision regulation of water circulation in British domestic heating circuits. This model has earned its reputation through decades of reliable service in millions of UK households, making it the most trusted name for professional heating engineers and homeowners looking for a "fit and forget" solution. IMPORTANT: THIS IS THE FULL UNIT. To ensure absolute clarity and prevent returns, please note that this listing includes the complete assembly: both the ZA5 actuator head and the 22 mm brass valve body. While many listings provide only the replacement head, this package provides the full thing required for a new S-Plan installation or a total valve failure replacement. TECHNICAL COMPATIBILITY WARNING: This unit utilizes an internal flat type valve rubber paddle to stop water flow. It is NOT a ball type valve. Before purchasing, please verify your existing valve body type; this actuator head is specifically designed for paddle-style stems and will not function on ball-style mechanisms. Using the wrong head on a ball-valve body can lead to system failure and leaks. The drayton 2 port valve 22mm compression ends are designed for a professional, leak-resistant connection to standard UK 22 mm copper or plastic plumbing pipes. The actuator features an integrated manual lever, which is critical for locking the valve in the "Open" position during the initial filling, venting, and commissioning of the central heating system. Its snap-on replacement design means the actuator head can be removed or replaced in seconds without touching the "wet-side" of the system, simplifying future maintenance. Electrically, the unit is pre-wired with a 1-metre, 5-core cable following industry-standard wiring logic for seamless integration into your existing S-Plan controls. The high-torque motor operates on 230 V AC and provides power-efficient performance with a consumption of just 5 W to 6 W. Whether you are performing a full new-build installation or a critical emergency repair, the Drayton 27100 offers the industrial build quality and proven pedigree required for a warm, efficient, and well-regulated home.
