Pneumatic stainless steel hard sealed butterfly valve D673W

In many factories and production workshops, equipment maintenance and upkeep have been required to be institutionalized and standardized,Pneumatic Butterfly ValveAlthough it is just an ordinary valve device, it is essential to take necessary maintenance measures in daily life to avoid affecting its use and extend its service life. So, what are the maintenance measures?

1、 Regular maintenance

Although it may not require daily maintenance, in order to ensurePneumatic Butterfly ValveBeing able to meet usage needs without sudden strikes catching people off guard, it is not possible to carry out daily maintenance. Regular personnel inspections are necessary. The regular maintenance of pneumatic butterfly valves includes checking the working condition of the valve, inspecting the corrosion of valves used for controlling and processing chemical media fluids, checking for noise during operation, ensuring good sealing of the valve, and checking for fluid leakage when the valve is closed. For pneumatic butterfly valves used in hydropower plants, it is also necessary to check whether the valve switch is blocked. If there is a blockage, it should be cleaned in a timely manner, otherwise it will greatly affect the effectiveness of the pneumatic butterfly valve.

2、 Maintenance and repair

Mechanical equipment malfunctions are inevitable, except for regular maintenancePneumatic Butterfly ValveIn addition to cleaning, it is also necessary to ensure the good sealing of the valve, and regularly verify the performance of the pneumatic butterfly valve. If possible, it is best to conduct equipment and instrument testing on the pneumatic butterfly valve. In the event of a malfunction, it is important to promptly seek professional maintenance personnel to repair and replace damaged components. In addition, proactive maintenance work before the malfunction is also crucial.

Pneumatic Butterfly ValveThe service life is related to the quality of the product itself, whether the later maintenance is in place, and whether the correct usage method is followed.

Basic InformationProduct information

Product Name: Pneumatic Stainless Steel Hard Seal Double Clamp Butterfly Valve

Product model: D673W

Product Introduction:

The D673W pneumatic stainless steel hard sealed butterfly valve is composed of a new aluminum alloy shell pneumatic actuator and a stainless steel metal hard sealed three eccentric butterfly valve. Pneumatic actuators with double acting and single acting (spring reset), gear transmission, safe and reliable, and can be equipped with various accessories according to user requirements. Butterfly valves use precision J-shaped elastic sealing rings and three eccentric multi-level metal hard sealing structures, and are widely used in industrial pipelines such as metallurgy, power, petrochemicals, water supply and drainage, and municipal construction where the medium temperature is ≤ 425 ℃, for regulating flow and carrying fluids.
