Pneumatic knife gate valve is a valve that uses a pneumatic actuator to control the valve, so as to realize the opening and closing of the valve. It can be divided into two parts, the upper part is the pneumatic actuator, the lower part is the valve.
The valve has developed from a general industrial pipeline to a professional pipeline system such as food, health and medicine.
Ultra-thin knife gate valve with its small size, small flow resistance, light weight, easy to install, easy to disassemble and other advantages to completely solve the general gate valve, flat gate valve, ball valve, globe valve, regulating valve, butterfly valve and other valves of large flow sun, large weight, difficult installation, occupy a large area and other difficult problems. With the advent of tool gates, a large number of general purpose cut-off valves and regulating valves have been replaced by them.
