Product Description
Product Description
This is a manual wafer-type butterfly valve, which is commonly used in piping systems to control the on/off or flow regulation of fluids (such as water, gas, etc.). Here are the core product details:
I. Structure & Material
- Main Structure:Consists of a valve body (ductile iron with blue anti-corrosion coating), a handle (for operation), a valve disc (sealing core, mostly rubber-coated metal), and a valve stem (connecting the handle and valve disc).
- Sealing Material:The sealing element between the valve disc and seat is mostly rubber (e.g., EPDM rubber), which is temperature-resistant, corrosion-resistant, and ensures sealing performance.
II. Function & Operation
- Manual Control:Rotate the handle (within a 90° range) to drive the valve stem, making the valve disc rotate synchronously to achieve "full open-full close" or flow regulation.
- Bidirectional Flow:Most butterfly valves support bidirectional medium flow (pay attention to flow direction markings for some models), allowing flexible installation.
III. Core Parameters (Subject to Specific Models)
- Nominal Diameter (DN):E.g., DN50/DN100 (corresponding to the inner diameter of the pipeline).
- Nominal Pressure (PN):Commonly PN10/PN16 (withstanding 1.0MPa/1.6MPa pressure).
- Applicable Temperature:Rubber-sealed models are generally -10ºC~120ºC (special materials are required for high-temperature scenarios).
- Connection Method:Wafer-type (no flanges at both ends of the valve body; it needs to be clamped between pipeline flanges for installation).
IV. Application Scenarios
Widely used in water supply and drainage systems (tap water, sewage pipelines), fire protection pipelines (sprinklers, fire hydrant systems), HVAC systems (cold/hot medium transmission), and light industry pipelines (e.g., fluid control in food and pharmaceutical industries).
V. Product Features
- Lightweight & Efficient:Compact structure, light weight, low opening/closing torque, and convenient manual operation.
- Low Resistance & Energy-saving:Smooth flow channel, low fluid resistance, and lower energy consumption.
- Reliable Sealing:Rubber elastic sealing design with minimal leakage (meeting national standard sealing grades).
VI. Installation & Maintenance
- Installation:Ensure pipeline cleanliness, and install the handle in an easily operable direction; for wafer-type valves, evenly tighten flange bolts to avoid valve body deformation.
- Maintenance:Regularly check the aging of sealing elements, lubricate the valve stem (to prevent jamming), and clean impurities in the valve cavity.
