MULTI-FUNCTION CONTROL VALVE / TRIPLE CHECK VALVE
Product Model: HH49X
Product Overview
The HH49X Multi-Function Control Valve / Triple Check Valve is designed to prevent backflow and provide three functions in one valve: non-water hammer check, gate valve, and balancing valve. It is suitable for water supply and drainage systems, HVAC systems, and boiler condensate systems in buildings, apartments, and factories. The valve ensures safe operation by preventing reverse flow and potential damage to pumps and pipelines.
Key Features
- Triple Functionality
- Non-Water Hammer Check: Prevents water hammer and noise during closure.
- Gate Valve: Acts as a shut-off valve to control flow.
- Balancing Valve: Maintains system balance and regulates pump output.
- Backflow Prevention
- Automatic Operation: Opens and closes with media flow to prevent reverse flow.
- Water Hammer Prevention: Slow closure reduces pressure surges and protects pipelines.
- Efficient Design
- Low Resistance: Streamlined design minimizes pressure drop and energy loss.
- Versatile Installation: Suitable for both horizontal and vertical installations.
- Durable Construction
- High-Quality Materials: Constructed from corrosion-resistant materials for long service life.
- Reliable Sealing: Ensures tight closure and prevents leakage.
- User-Friendly Features
- Indicator: Visual confirmation of valve opening degree.
- Adjustable Output: Regulates pump output by adjusting the opening degree.
