Product DescriptionPneumatic control valves are all kinds of
pneumatic components that control the pressure, flow and flow
direction of airflow in pneumatic systems and ensure the normal
operation of pneumatic actuators or agencies. It is a type of
valve that uses a circular disc or plate, known as the butterfly,
to control the flow of fluid through the valve.Our AdvantagesThe
main advantages of the pneumatic butterfly valve are its simple
structure, small size, light weight, and low cost. These advantages
are particularly significant for the pneumatic butterfly valve,
which can be installed in high-altitude tunnels and is easy to
operate through the control of a two-position five-way solenoid
valve. The valve can also adjust the flow of the medium. The fluid
resistance is small, and the effective flow area is large when the
pneumatic butterfly valve is fully open, especially for medium and
large diameters. The valve opens and closes quickly and easily,
with the disc rotating 90 degrees to complete the opening and
closing. Due to the nearly equal forces on both sides of the
butterfly disc, the torque direction is opposite, resulting in a
small opening and closing torque. Good sealing can be achieved
under low pressure, and the sealing materials for the butterfly
valve include NBR rubber, fluorine rubber, edible rubber, and PTFE
lining, which have excellent sealing performance. Among them, the
hard-sealed butterfly valve has the significant advantages of metal
hard sealing and elastic sealing with a soft-hard layered metal
sheet, and has excellent sealing performance even at low
temperaturesScope of Application1. Chemical industry: Pneumatic
butterfly valves are used in chemical plants to control the flow of
chemicals, including acids, bases, and solvents.2. Water treatment:
Pneumatic butterfly valves are used in water treatment plants to
control the flow of water and other fluids, including wastewater,
slurry, and chemicals.3. HVAC systems: Pneumatic butterfly valves
