Product Description
Grooved Turbine Signal Butterfly Valve Product Details
1. Overview
The Grooved Turbine Signal Butterfly Valve integrates flow control and signal feedback functions. It is widely used in pipeline systems for fire protection, water supply/drainage, HVAC, gas, petroleum, and chemical industries. It is especially critical in automatic sprinkler fire-extinguishing systems to prevent misoperation (e.g., accidental valve closure) that could compromise fire suppression.
2. Structural & Driving Features
- Transmission & Signal Mechanism: Equipped with a worm-gear drive and cam mechanism. When the valve rotates 0°-90° (full open/close), it outputs "on/off" electrical signals to a control center, enabling real-time monitoring of the valve's status (e.g., an alarm triggers if the valve is mistakenly closed by 20%-25%).
- Materials & Sealing:
- Valve Body: Ductile iron (stainless steel optional) with epoxy powder coating for corrosion resistance.
- Butterfly Disc: Fully rubber-lined (nitrile rubber or PTFE) for bidirectional sealing (zero leakage in gas tests). Compatible with media like water, oil, and foam mixtures.
3. Performance Advantages
- Installation & Operation:
- Grooved (Clamp) Connection: Enables fast, flexible installation at any angle (no restriction from medium flow direction).
- 90° Rotation: Quick opening/closing with low operating torque (easy to operate).
- Flow Control:
- Large flow area, low flow resistance, and near-linear flow characteristics ensure high regulation accuracy and minimal pressure loss (energy-efficient).
- Durability & Reliability:
- Compact design with few components; tested for tens of thousands of opening/closing cycles.
- Vibration/noise reduction capabilities; accommodates pipeline thermal expansion and axial misalignment.
4. Technical Parameters (Typical Range)
| Parameter | Typical Range |
|---|
| Nominal Diameter | DN50-DN300 (customizable for larger sizes) |
| Nominal Pressure | 0.6-1.6 MPa (up to 2.5 MPa for some models) |
| Operating Temperature | -20°C-80°C (standard: 0°C-80°C) |
| Body Material | Ductile iron / Cast steel / Stainless steel |
| Sealing Material | Nitrile rubber / PTFE |
| Actuation | Manual (turbine), electric, pneumatic |
5. Installation & Maintenance
- Installation:
- Store indoors (dry environment) before installation; keep the disc slightly open (4°-5°).
- Install in accessible locations for maintenance; compatible with grooved pipe fittings.
- Maintenance:
- Simple structure for easy disassembly and repair.
- Signal devices are integrated into the worm-gear box (moisture/fire-resistant for high reliability).
6. Certification & After-Sales
- Certifications: Compliant with GB5135.6; some models feature CCC certification.
- Warranty: 24-month warranty (free replacement for quality issues; technical support provided).
7. Application
This valve is a core control component in industrial and civil pipeline systems-especially in fire protection-due to its efficient flow control, reliable signal feedback, and easy installation/maintenance.
Note: Specific parameters may vary by model. Consult technical documentation for detailed specifications.
