• Pneumatic two shut-off valve is one element of industrial production process automation, pneumatic unit combination instrument actuator. He supplied the instrument in accordance with the control signal, open or cut off the pipeline flowing medium (water, steam, etc.), in order to meet the system pressure, temperature, flow and other parameters of industrial requirements.
• This type of product is the company absorbing foreign advanced technology and design of a new generation of precision casting stainless steel shut-off valve. It skidding quality, beautiful appearance, light weight, small size, long life, easy installation and maintenance in one of the other advantages. Competent in the use of nitrogen vulcanization. The main performance indicators have reached the level of similar imported valves.
• The product performance standards: HG / T3236-1989 “rubber machinery pneumatic two shut-off valves” applies to the use of JIS (Japanese Industrial Standards), API (American Petroleum Institute standard) or DIN (German industrial standard) flange connection system .

Cấu trúc và nguyên tắc van piston máy lưu hóa cao su ZSQ403-FR 

Pneumatic two shut-off valve, the piston actuator and shut-off valve of two parts. When there is no signal, by spring preload, turn off the spool on the valve seat; when the input signal, the piston moves the stem down run, will close the valve under the seat. Three-way and two-way shut-off valve shut-off valve is different from the lower end, the former is equipped to take over, you can draw a line a pipeline loop; the latter is closed bonnet.
