Product Description
DN1000 Butterfly Valve Instruction Manual
1. Product Overview
This DN1000 butterfly valve is a high - performance valve designed for various industrial and civil pipeline systems. It is used to control the flow and cut - off of media in pipelines, featuring reliable performance, convenient operation, and a compact structure.
2. Technical Specifications
- Nominal Diameter: 1000mm
- Nominal Pressure: PN10, PN16, etc. (Available pressure ratings can be selected according to specific requirements)1
- Material of Construction
- Valve Body: Usually made of ductile iron GGG50. It can also be made of other materials such as cast steel ASTM A216 WCB according to different application scenarios.
- Disc: Commonly made of stainless steel 304 or 316. Aluminium bronze is also an option for specific media3.
- Sealing Ring: EPDM is often used, which has good sealing performance and corrosion resistance. For special requirements, PTFE - lined or other materials can be selected.
- Stem: Generally made of stainless steel 316 to ensure good corrosion resistance and mechanical strength.
- Operating Temperature Range: - 15°C to + 130°C (The specific range may vary depending on the material of the sealing ring and other components)3.
- Applicable Media: Water, sewage, gas, oil, and some non - corrosive or mildly corrosive fluids.
3. Structure and Working Principle
- Structure
The valve consists of a valve body, a disc, a stem, a sealing ring, and other components. The disc is connected to the stem and located inside the valve body. The sealing ring is installed between the disc and the valve body to achieve a tight seal when the valve is closed.
- Working Principle
The valve operates by rotating the disc around the stem axis. When the disc rotates 90 degrees from the closed position to the open position, the medium can flow through the valve. Conversely, when rotated back to the closed position, it blocks the flow of the medium.
4. Installation
- Installation Preparation
- Check the valve model, specification, and the direction of the arrow on the valve body to ensure it is consistent with the pipeline requirements.
- Clean the pipeline thoroughly to remove any debris, dirt, or welding slag.
- Installation Steps
- Place the valve in the pipeline according to the specified orientation. Ensure that the valve is properly aligned with the pipeline flanges.
- Align the valve flanges with the pipeline flanges and install the bolts. Tighten the bolts evenly in a criss - cross pattern to ensure a proper seal.
- If the valve is equipped with an actuator (such as an electric or pneumatic actuator), install it according to the actuator's installation instructions. Connect the actuator to the valve stem correctly and ensure proper operation.
5. Operation and Maintenance
- Operation
- Manual operation: Use the handwheel or lever to rotate the disc. Clockwise rotation usually closes the valve, and counter - clockwise rotation opens it. For valves with a manual gearbox, operate the gearbox to achieve the opening and closing of the valve.
- Actuator - controlled operation: For valves with actuators, follow the control system's operating instructions to open and close the valve. Set the appropriate parameters and control modes according to the actual needs.
- Do not exceed the rated pressure and temperature during operation. Avoid sudden opening and closing of the valve to prevent water hammer and other phenomena.
- Maintenance
- Regularly check the valve for any signs of leakage, especially around the sealing surfaces and the stem packing. If leakage is found, take timely measures to repair or replace the sealing components.
- Lubricate the stem and other moving parts regularly according to the recommended lubrication schedule to ensure smooth operation. Use the appropriate lubricant according to the working environment of the valve.
- Inspect the valve body and disc for any signs of corrosion or wear. If there is severe corrosion or wear, replace the damaged parts promptly.
- Check the tightness of the bolts and other connections regularly to ensure that they are not loose. Tighten the loose bolts in a timely manner.
6. Troubleshooting
| Problem |
Possible Cause |
Solution |
| Leakage at the valve body |
Damaged sealing ring; Loose flange bolts |
Replace the sealing ring; Tighten the flange bolts evenly |
| Difficulty in operating the valve |
Lack of lubrication; Stem deformation; Actuator failure |
Lubricate the moving parts; Check and repair or replace the stem; Check and repair the actuator |
| Stem leakage |
Worn - out stem packing; Damaged stem surface |
Replace the stem packing; Polish or replace the stem if the surface is damaged |
7. Storage
- Store the valve in a dry, clean environment. Avoid storing it in a humid or corrosive environment.
- Protect the valve from direct sunlight, rain, and other adverse weather conditions.
- If the valve is to be stored for an extended period, it is recommended to coat the exposed metal parts with a rust - preventive agent. Cover the valve with a protective cover to prevent dust and debris from entering.
