Pneumatic three eccentric all metal sealed butterfly valve description:

The pneumatic butterfly valve is a metal hard sealing butterfly valve developed and produced independently by our factory, combined with a pneumatic actuator, which can play a good cutting role. Its main characteristics: 1. The butterfly valve adopts a three-dimensional eccentric structure, and the valve plate only contacts the valve seat at the moment of closure, reducing wear between sealing surfaces, extending service life, and achieving better sealing effect; The sealing ring adopts all metal sealing ring, which is wear-resistant and resistant to medium erosion; The valve seat is welded with hard alloy, which is wear-resistant and resistant to medium erosion, increasing the service life of the valve. 2. The pneumatic actuator adopts a high-strength 104 alloy die-casting body, with a split drive cylinder suspended at both ends coated with high hardness and wear-resistant materials. The sealing component and wear-resistant component are designed with a U-shaped output axis, ensuring the online operation reliability of the actuator under high torque, large temperature difference, and high opening and closing speed. The pneumatic quick closing butterfly valve composed of the above components is driven by a 0.4-0.7MPa air pressure source provided by the main system to perform a 0-90 ° opening and closing action on the valve.

Debugging

This system has been validated for all indicators on the testing bench before leaving the factory. No on-site debugging by the owner is required. By correctly connecting the driving air source and electromagnetic valve power supply, it can operate normally. If there are any abnormal situations during the trial operation, please contact our factory in a timely manner. Our factory can dispatch personnel to solve the problem within 24 hours (remote support to foreign customers).

Installation precautions

1. The valve should not be bumped during transportation to avoid damaging the sealing surface.

2. Valves should be stored in a cool and dry place for a long time, and should not be stacked or stacked.

3. Before installing the valve, the following work should be carried out:

(1) Wipe off any dirt attached to the valve;

(2) Verify whether the working conditions match the pressure resistance, temperature resistance, and corrosion resistance of the valve;

(3) Check that all fasteners of the valve are not loose or damaged;

(4) Manual opening and closing of valves should be flexible and free of jamming;

(5) Valves opened and closed with handles should be checked for damage to the positioning plate. When opening and closing, the positioning claw should be removed from the positioning plate before opening and closing operations can be carried out.

5, Maintenance instructions

1. Regular inspections should be conducted on the joints and air pipes of the control air circuit to check for any leaks, and any leaks should be promptly resolved.

2. Strengthen the management of gas source purification projects, promptly remove condensate from filters, and ensure that the gas supply pressure is not lower than the specified value.

3. During maintenance, the air source filter should be cleaned to prevent excessive accumulation of impurities that may affect the normal operation of other accessories.
