Stainless Steel Food Grade Welding Pneumatic Diverter Shut Off Valve
The stainless steel sanitary pneumatic stop valve is designed for high-cleanliness process pipeline systems to ensure the hygienic safety and efficient discharge of fluid control. Its spherical base structure reduces the residual medium, optimizes the self-draining capacity, avoids the risk of contamination, and meets the requirements of CIP/SIP online cleaning and disinfection. The pneumatic drive method improves the level of automation control, improves production efficiency, and reduces human errors. It is widely used in the pharmaceutical, food, biotechnology and other industries to ensure a sterile process environment and meet strict hygiene standards, while enhancing the reliability and stability of the system and nsuring product quality and safety.
Working Principles
The working principle of the stainless steel sanitary pneumatic stop valve is to rely on the air source to drive the piston to move, thereby driving the valve stem and valve core to move up and down to realize the opening and closing of the valve. Under normal conditions, the valve can be set to normally closed or normally open mode. When the air source enters the actuator, the piston is pushed by the air pressure, causing the valve stem to move up or down, driving the valve core to leave or press the valve seat, thereby controlling the flow of the medium. Using a stainless steel sanitary pneumatic stop valve can reduce flow resistance and reduce the damage of turbulence to the medium.
The options of stainless steel sanitary pneumatic stop valves include:
Drive mode: normally closed (NC), normally open (NO), double acting (AA).
Control mode: solenoid valve, limit switch, position feedback, intelligent control unit.
Seal material: EPDM, PTFE, FKM (compliant with FDA/USP standards).
Valve body material: 316L stainless steel, with optional surface polishing level.
Connection mode: welding, quick installation, thread, flange.
Flow direction design: straight-through, T-type, Y-type, multi-channel structure.

Features
● The stainless steel sanitary pneumatic stop valve optimizes the fluid discharge path, reduces media residue and dead corners, improves self-drainage ability, ensures high cleanliness, and is suitable for sterile environments.
● The stainless steel sanitary pneumatic stop valve adopts a high-response pneumatic piston structure to achieve rapid opening and closing, improve the accuracy of automatic control, and is suitable for high-frequency operating systems.
● The internal flow channel of the stainless steel sanitary pneumatic stop valve is optimized to ensure complete isolation between different media, prevent cross contamination, and improve fluid purity and product quality.
● The internal flow channel of the stainless steel sanitary pneumatic stop valve is optimized by fluid mechanics to reduce turbulence and shear force, and is suitable for handling high viscosity, suspension or easily degradable fluids.
● The stainless steel sanitary pneumatic stop valve supports T-type, Y-type and multi-channel designs to achieve flexible switching of media flow direction, simplify pipeline layout, and improve system integration.
● The surface roughness of the stainless steel sanitary pneumatic stop valve body can be as low as Ra 0.4μm, which reduces microbial attachment, improves cleaning effect, and complies with GMP and FDA standards.
