Description
Tower ABBV1ST Straight Automatic Bypass Valve
The Tower ABBV1ST is a straight automatic bypass valve designed for heating systems where a boiler bypass is necessary. It is particularly useful in systems fitted with thermostatic radiator valves (TRVs) and allows pump overrun operation after zone valves have closed. This valve ensures smooth operation by maintaining consistent system pressure and providing a constant flow through the boiler.
As TRVs gradually close with increasing room temperatures, the ABBV1ST adjusts its flow rate to compensate for rising system resistance, maintaining the desired pre-set differential pressure. This helps to reduce noise caused by closing TRVs or zone valves, minimise pump impeller wear from high resistance, and extend the life of the boiler’s heat exchanger by ensuring a steady minimum flow rate.
For installation, place the ABBV1ST in a loop between the flow and return after the pump, ensuring the flow direction matches the arrow on the valve body. Adjust the setting using the adjustment head, lock it in place with the top screw, and refer to boiler instructions for the recommended settings.
Key Features:
- High Flow Rate: Capable of handling up to 50 litres per minute.
- Pressure Range: Adjustable differential pressure between 0.1 and 0.6 bar.
- 22mm Compression Fittings: Easy-to-fit standard fittings for seamless integration.
- Noise Reduction: Minimises noise caused by TRVs and zone valve operation.
- Pressure Regulation: Maintains even system pressure for optimal performance.
- Constant Flow: Ensures a steady flow through the boiler.
- Lockable Adjustment: Securely locks the set pressure for precision and reliability.
Technical Specifications:
- Flow Capacity: Handles up to 50 litres per minute.
- Pressure Range: 0.1–0.6 bar.
- Fittings: 22mm compression.
- Application: Suitable for TRV systems and pump overrun operation.
The Tower ABBV1ST is a vital component for optimising heating system efficiency and longevity. Its robust design, easy adjustability, and noise reduction capabilities make it a dependable choice for both professional installers and homeowners.
