Product DescriptionBlind 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.Product
