Product features

Stainless steel pneumatic ball valve is composed of stainless steel hard seal ball valve, pneumatic actuator and other related accessories. It uses air source to drive the valve to open and close. The stainless steel pneumatic ball valve body material is made of stainless steel, which has super tensile resistance, wear resistance and corrosion resistance. It can not only be used in normal temperature and atmospheric pressure occasions, but also suitable for ultra-high pressure and low pressure drop The highest temperature can reach 550 ℃. The stainless steel pneumatic ball valve can be equipped with a valve positioner according to the working conditions, and the analog signal of 4-20mA is input to achieve the percentage adjustment and control of the opening of the ball valve.
 
Stainless steel pneumatic ball valve performance advantages:
1. The stainless steel ball valve is made of Silicon Sol precision casting and connected with pneumatic actuator. It can be used not only as switch cut-off function, but also as flow regulation function.
2. Diversified selection, through the selection of different valve body, seat material, 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. If there is air leakage, the gas can be discharged directly, which has no pollution to the environment and has high safety.
Stainless steel pneumatic ball valve accessories options:
Feedback device: also known as limit switch, remote feedback switch signal (explosion-proof)
Solenoid valve: two position five way for double action and two position three-way for single action (explosion-proof)
Triplet: it can stabilize the air source, filter and add lubricating oil to the cylinder
Cut off type accessories: single electric control solenoid valve, double electric control solenoid valve, limit switch feedback device.
Adjustable accessories: Electric positioner, pneumatic positioner and electric converter.
Air source treatment accessories: air filter pressure reducing valve, air source treatment triple piece.
Manual mechanism: turn handwheel mechanism, manually open and close valve
