Product Description

316L Stainless Steel Food Grade Pneumatic Double Acting TC 180 Degree Two-Way Dosing Handling Valve

 

A is a specialized flow control device used in hygienic processing systems. It allows for precise regulation of fluid through a butterfly-style disc that can be finely adjusted. Designed for clean-in-place (CIP) and sterile environments, it features a smooth, crevice-free surface to prevent contamination, making it ideal for food, beverage, and pharmaceutical applications.

Working principle
The stainless steel sanitary metering butterfly valve operates by rotating a disc inside the valve body to regulate flow. When the handle or actuator turns, the disc pivots within the flow path. Precise metering is achieved by positioning the disc at specific angles, allowing controlled flow rates. Its tight sealing surface ensures minimal leakage. The smooth internal surfaces help maintain hygiene and make cleaning easy, supporting CIP/SIP processes in sanitary environments.

Size range: 1" ~ 4" or DN25 ~ DN100
Connection: quick-release, welding, thread
Operation: manual, pneumatic, electric
Control characteristics: adjustable angle 0°~90°, fine positioning
Working pressure: 0~10 bar (customizable)
Working temperature: -10ºC ~ +120ºC

Product Recommendations

 

Product Description

Stainless steel sanitary valves are widely used in high-cleanliness industries and have the following significant advantages:
1. Accurate Flow Control
Provides precise adjustment through a calibrated scale, ensuring accurate flow regulation for sensitive dosing applications. Ideal for hygienic and process-critical systems.

2. Minimal Product Disturbance
Engineered for smooth laminar flow, the valve reduces turbulence and shear stress, helping to preserve product quality in delicate processes.

3. Leak-Resistant Sealing
Features a tight-sealing seat that ensures drip-free operation, even during partial openings, maintaining sanitary conditions and reducing waste.

 

4. Dual-Direction Capability
Supports bidirectional flow modulation, increasing system flexibility and reducing the need for multiple valve types in compact piping setups.

5. Visual Position Indicator
Equipped with a clear position scale for easy visual feedback, ensuring reliable manual control and simplifying system calibration.

6. Space-Saving Design
Combines shutoff and metering functions in one unit, reducing system complexity, installation space, and overall equipment cost.
