What is the function of a sanitary pneumatic valve？

Sanitary pneumatic valve is a valve widely used in industries with high hygiene requirements, and its main functions are as follows:

Accurately control fluid flow rate

Adjustment function: Sanitary pneumatic valves can achieve precise adjustment of fluid flow through pneumatic actuators. For example, in the food processing process, it is necessary to transport liquid raw materials to the mixing tank at a precise flow rate. Sanitary pneumatic valves can accurately control the flow rate according to the set pressure or signal, ensuring the stability of product quality.

Quick response: The pneumatic system has a fast response speed, and the valve can complete opening and closing or adjusting actions in a short time, improving production efficiency. For example, in the feed process of reaction vessels in the pharmaceutical industry, sanitary pneumatic valves can quickly open or close to avoid material waste.

Ensure hygiene and safety

Pollution prevention: Sanitary pneumatic valves are usually made of corrosion-resistant and easy to clean materials such as stainless steel and polytetrafluoroethylene (PTFE), with a smooth surface, no dead corners, and no residual materials or bacterial growth. In industries such as food and pharmaceuticals, these characteristics can effectively prevent fluid contamination and ensure the hygiene and safety of products.

Compliant with hygiene standards: Its design complies with international hygiene standards (such as 3A, FDA, etc.) and can meet strict hygiene requirements. For example, in dairy production, sanitary pneumatic valves can prevent milk and other liquids from being contaminated by external factors, ensuring product quality and safety.

Implement automated control

Remote operation: Through pneumatic actuators and control systems, sanitary pneumatic valves can achieve remote control and automated operation. In large-scale production lines, operators can remotely control multiple valves through a central control system, reducing manual intervention and improving production efficiency and operational safety.

Integrated control: These valves can be integrated with automation equipment such as PLC (Programmable Logic Controller) to achieve complex process control. For example, in beverage filling production lines, sanitary pneumatic valves can accurately control the filling volume and speed of liquids based on PLC instructions.

Easy to clean and maintain

Easy to clean: The design of sanitary pneumatic valves considers the convenience of cleaning and can usually be cleaned in place (CIP) and disinfected in place (SIP). This means that the valve can be cleaned and disinfected without disassembly, greatly reducing maintenance time and costs.

Easy to maintain: Its structure is relatively simple, with fewer components, making it easy to disassemble and repair. For example, if the seal of the valve is damaged, maintenance personnel can quickly replace the seal and restore the normal function of the valve.

Adapt to various working conditions

High temperature and high pressure resistance: Sanitary pneumatic valves can withstand high working pressure and temperature, and are suitable for various complex working conditions. In the high-temperature sterilization process of the pharmaceutical industry, sanitary pneumatic valves can work normally to ensure the smooth delivery of sterilization solution.

Corrosion resistance: Due to the corrosion resistance of its materials, sanitary pneumatic valves can handle various corrosive fluids such as acids, alkalis, salts, etc., and are widely used in industries such as chemical and food.

Improve production efficiency

Reduce downtime: Due to its reliability and automation control capabilities, sanitary pneumatic valves can reduce downtime caused by equipment failures. In a continuous food processing line, the stable operation of sanitary pneumatic valves can ensure the continuity of production and improve overall production efficiency.

Optimizing process flow: By precisely controlling flow and pressure, sanitary pneumatic valves can optimize the production process, improve product quality and output. For example, in the process of beer brewing, sanitary pneumatic valves can precisely control the delivery of malt extract and the feeding of fermentation tanks, ensuring the quality and taste of beer.
