Audited Supplier Blind plate valves have the advantages of novel structure, wear resistance, reliable sealing, flexible operation, convenient installation, maintenance, and long service life. They are equipped with pipeline expansion devices, which can switch valve plates without affecting pipeline facilities. Especially suitable for situations that require quick cutting and reversing. The manual blind valve is equipped with a rotating connecting shaft spiral pair or worm gear transmission device, while the electric blind valve is equipped with an electro-hydraulic or electric push rod, which can achieve opening and closing operations and is an ideal equipment for switching sealing.
The main materials of manual blind valve are carbon steel, alloy steel, and stainless steel, which are good for cutting off harmful and toxic gas media in valve equipment. It has the characteristics of light weight and small volume, convenient operation, quick action, and absolutely reliable performance in cutting off other parts.
To maximize the advantages of blind valve, the correct operation method is as follows:
1. During the use of blind valve, other auxiliary tools should not be used, and the valve should be controlled by a control box or manual device.
2. Factors such as Thermal expansion and distortion of the pipeline shall not cause adverse effects on the working performance, so external forces shall not be applied or transferred to the blind valve.
3. Drive devices, screw rods, handwheels, and rear handles are not allowed for lifting purposes.
4. When operating, pay attention to observing the position indicator needle or dial. Clockwise means off, and counterclockwise means on.
