Precision small pneumatic ball valve is a right angle rotary switch valve, mainly used for cutting off and controlling media. This series of ball valves is suitable for tight cutting, fast cutting, and bidirectional cutting control of media. Paired with pneumatic actuators, electric actuators, and electric actuators, it is widely used in process control systems with high automation requirements such as papermaking, chemical, food processing, and petrochemical industries. Product features of compact pneumatic ball valve: 1. The fluid resistance is small and the pressure drop is low. A fully open ball valve is a straight through pipeline, so the fluid resistance is very small, and the medium passing through the valve body has almost no pressure loss. 2. Upper and lower bearing design: The valve body is equipped with upper and lower bearings, which have a large contact area with the valve stem, high load-bearing capacity, low friction coefficient, and reduce the torque of the valve. 3. The valve seat can be selected as metal hard seal or PTFE soft seal according to the needs of the medium and working conditions: the sealing surface of the metal hard seal valve seat is welded with hard alloy, and the ball surface is plated with hard chromium or hardened by spray welding, ion nitriding, etc., which enhances the service life and temperature resistance of the sealing surface; Soft sealed PTFE valve seats or reinforced PTFE valve seats have good sealing performance, corrosion resistance, and a wide range of applications. 4. High degree of self-control: The valve body is directly assembled with pneumatic or electric actuators, suitable for automation control systems with high degree of self-control. 5. Wide applicability of media: The hard sealed valve seat and ball have a wiping effect during the switching process, which is not only suitable for liquid media, but also more suitable for system control with fiber and solid particle media. Design standards for compact pneumatic ball valves: Design standard: GB/T 12237_2007 Flange Standard GB/T 9113.1_2010 JB/T 79.1 -1994 HG 20592 -2009 ASME B 16.5 EN 1092 -1：2001 Pressure temperature rating: GB/T 1224 -2007 ASME B 16.34 -2003 ISO 7005 – 1 Strength and sealing test standards JB/T 9092 -1999 Product features of compact pneumatic ball valve: 1. The fluid resistance is low and the pressure drop is small. A fully open ball valve is a straight through pipeline without variable diameter, so the fluid resistance is very small, and the medium passing through the valve body has almost no pressure loss. 2. Upper and lower bearings: The valve body is equipped with upper and lower bearings, which have a large contact area with the valve stem, high load-bearing capacity, low friction coefficient, and reduce the torque of the valve. 3.

High degree of self-control: The valve body is directly assembled with pneumatic or electric actuators, suitable for automation control systems with high degree of self-control. 5. Wide range of medium adaptability: The hard sealed valve seat and ball have a wiping effect during the switching process. In addition to being suitable for liquid media, it is more suitable for system control with fiber and solid particle media. 6. The structural design is reasonable, the manufacturing process is excellent, the valve sealing performance is excellent, the torque is small, the corresponding specifications of the supporting actuator are small, and it is economical and durable.
