The duckbill shape enhances the valve's sealing capabilities, ensuring a tight closure that prevents leaks even in high-pressure and high-flow systems.

3. Multi-Position Adjustment Handle

The multi-position adjustment handle allows for easy and precise control of fluid flow. Operators can select various positions, providing flexibility to meet specific operational needs without requiring additional tools or complex adjustments.

4. Space-Saving and Easy Installation

The butterfly valve design offers a compact, space-saving solution, perfect for tight spaces. Its simple installation process reduces downtime and installation costs.

5. Durable and Long-Lasting

Built to withstand the toughest conditions, this valve is designed for longevity, reducing the need for frequent replacements and minimizing operational downtime.

Technical Specifications

Operating Instructions

Proper operation of the Fluorine-Lined Duckbill Multi-Position Adjustment Handle Butterfly Valve ensures its longevity and optimal performance. Here are the key steps for safe and efficient operation:

1. Valve Orientation and Installation

Before installing the valve, ensure that the flow direction is correctly aligned with the valve body. The valve can be installed in either horizontal or vertical positions, but it is recommended to install the actuator in the vertical upward position to facilitate proper drainage and ensure optimal performance.

2. Operating the Multi-Position Handle

• Adjust the Handle: The multi-position handle allows you to adjust the valve in incremental positions. Turn the handle in a clockwise direction to close the valve and counterclockwise to open it. For finer control, adjust the handle slowly and check the valve’s movement at each position.

• Flow Control: For precise flow control, stop at intermediate positions to modulate the flow rate. Each position corresponds to a specific flow opening, providing flexibility to adjust the valve to the system’s requirements.

3. System Pressurization

• Ensure that the system is properly pressurized and that the valve is securely seated. Use a pressure gauge to check system pressure before opening the valve.

• Gradual Adjustment: When opening or closing the valve, ensure gradual movement to prevent shock loads on the valve and piping system.

4. Emergency Shutoff

• In case of an emergency or system malfunction, quickly turn the valve handle to the closed position. The fluorine lining will provide a reliable seal to prevent leaks or fluid spillage.

Safety Operating Guidelines

Safety is paramount when working with any industrial valve. Follow these safety guidelines to ensure safe operation and protect both operators and equipment:

1. Personal Protective Equipment (PPE)

• Always wear the appropriate PPE such as gloves, safety goggles, and protective clothing when operating or maintaining the valve, especially when handling corrosive fluids.

2. Pressure and Temperature Limits

• Ensure that the valve is operated within the specified pressure and temperature ranges to avoid damaging the valve and surrounding equipment.

• Check System Pressure: Before operating the valve, confirm that the system is operating at the correct pressure. Overpressure can damage the valve and lead to safety hazards.

3. Valve Actuation

• Never attempt to force the handle or actuator when adjusting the valve. If resistance is encountered, stop and inspect the valve for potential blockages, damage, or system issues.

4. Handling Chemicals

• Always follow chemical safety guidelines and use the correct materials when handling aggressive fluids to prevent accidents.

Daily Maintenance

Regular maintenance of the Fluorine-Lined Duckbill Multi-Position Adjustment Handle Butterfly Valve will ensure its continued reliable performance. Below are the daily maintenance procedures:

1. Visual Inspection

• Inspect the Valve Body: Look for any signs of corrosion or damage to the fluorine lining. If you notice any defects or wear, replace the valve immediately.

• Check the Handle and Actuator: Ensure that the handle operates smoothly and the actuator is functioning properly. If the handle becomes stiff or difficult to turn, lubricate the moving parts.

2. Cleaning

• Clean the Valve Body: Periodically clean the valve using a non-abrasive cloth to remove dirt and chemical residues from the external parts. Use compatible cleaning agents to avoid damaging the fluorine lining.

• Air Filter Maintenance: If the valve is pneumatic, ensure that the air supply is clean, dry, and filtered to prevent contamination of the actuator.

3. Leak Checks

• Leak Detection: Perform a visual check around the valve body, handle, and connections for any signs of fluid leakage. If leaks are detected, shut off the system and inspect the valve for faulty seals or gaskets.

4. Lubrication

• Lubricate the valve’s moving parts, such as the handle and actuator shaft, using a suitable lubricant to ensure smooth operation.

5. Functional Test

• Operational Check: Test the valve by opening and closing it a few times to ensure smooth, resistance-free operation.

• Pressure Testing: Perform routine pressure tests to verify the integrity of the valve and its connections.
