Summary:
Pneumatic high pressure gate valve is composed of forged high pressure gate valve and pneumatic execution installation, mainly used in medium more complex high temperature and pressure conditions. Compared with other valve products, it is characterized by high temperature and pressure resistance, and has a unique self-sealing design, that is, the higher the pressure, the more reliable the seal. Due to the special performance, technical characteristics and working conditions, the product has formed the characteristics that other products can not be replaced. Pneumatic high pressure gate valve depends on the actuator of the air source pressure to drive the opening and closing of the valve, and the use of pressure to drive the gate to do the operation of the rise and fall, so as to connect (full open) and cut off (full closed) pipeline fluid medium. Nominal pressure can reach more than 25 mpa, diameter by 50 to 600 mm, temperature range in - 29 ° C to 550 ° C.

Advantages:
1. Low fluid resistance, small medium erosion and erosion of sealing surface (high gate opening height).
2. It has strong opening, good sealing performance, unlimited media flow direction with no turbulence and no pressure drop.
3. It has simple shape, good manufacturing technology and wide range of application.
