Product features

The stainless steel pneumatic ball valve is composed of a stainless steel hard sealed ball valve, a pneumatic actuator and other related accessories. The valve is opened and closed by means of air source drive. The stainless steel pneumatic ball valve body is made of stainless steel, which has super tensile strength, wear resistance and corrosion resistance. It can not only be used in normal temperature and pressure situations, It is also suitable for pipelines with relatively poor working conditions such as ultra-high pressure and low pressure drop, and the maximum temperature can reach 550 ℃. The stainless steel pneumatic ball valve can be equipped with a valve positioner according to the working conditions, and the 4-20mA analog signal can be input to adjust and control the percentage of the ball valve opening.
 
Performance advantages of stainless steel pneumatic ball valve:
1. The stainless steel ball valve is made of silica sol precision casting and connected with the pneumatic actuator. It can not only be used as a cut-off switch, but also as a flow regulator.
2. Diversified selection. By selecting different valve body and valve seat materials, it can be used in different working conditions.
3. It can be widely used in normal temperature and pressure, high temperature, high pressure and low temperature conditions.
4. The pneumatic stainless steel ball valve uses gas as the power source, and the pressure is generally about 0.4-0.7MPa, which is relatively safe. In case of air leakage, the gas can be discharged directly, which has no pollution to the environment and high safety.
Stainless steel pneumatic ball valve accessory options:
Echo: also called limit switch, remote feedback switch signal (explosion-proof)
Solenoid valve: double acting two position five way, single acting two position three way (explosion-proof)
Triple part: it can stabilize the air supply, filter, and add lubricating oil to the cylinder
Cut off accessories: single electric control solenoid valve, double electric control solenoid valve, limit switch annunciator.
Adjustable accessories: electric positioner, pneumatic positioner, electric converter.
Air source treatment accessories: air filter pressure reducing valve, air source treatment triplet.
Manual mechanism: turn the handwheel mechanism to manually open and close the valve
