Efficiency and Safety in Chemical Engineering: Experience the Power of Automated Plastic Valves and Precise Measurement Technology

Automatic Valves Made of Plastic - Measurement and Control for Efficient and Safe Production

In chemical and process engineering, precise measurement and control of processes are vital to ensure efficient and safe production. Float flow meters are a reliable and accurate method for measuring the flow rate of liquids and gases, making them suitable for various applications.

Plastic automatic valves, including ABS, PVC U, PVC C, PP, and PTFE valves, are widely used for regulating flow and pressure in pipeline systems. These valves offer excellent resistance to chemicals and corrosion, ensuring high operational safety. Pressure relief valves and pressure reducing valves ensure constant pressure regulation, while solenoid valves are employed for precise control of liquids and gases.

Measurement technology holds significant importance in chemical and process engineering. Accurate measurements of temperature, pressure, and flow rate are essential for process control and maintaining product quality. Modern measurement technology provides high accuracy, reliability, and enables automated monitoring and control of processes.

Overall, measurement and control are indispensable for efficient and safe production in chemical and process engineering. Float flow meters, plastic automatic valves, pressure relief valves, pressure reducing valves, solenoid valves, and modern measurement technology offer a cost-effective and reliable solution to meet industry requirements.

At our webshop, we offer a comprehensive range of products, including float flow meters and automatic plastic valves. Our selection includes electric ball valves made of PVC U, PVC C, ABS, PP, and PVDF, as well as pneumatic ball valves constructed from the same materials. Additionally, our automated diaphragm valves made of PVC U, PVC C, ABS, PP, and PVDF are known for their durability and high quality. We also provide pressure relief valves and pressure reducing valves made from various plastics.

We are actively seeking qualified suppliers and providers who can offer corresponding products in the field of plastic valves and measuring technology. These valves are essential in plant construction, particularly in chemistry and process engineering, and they serve a crucial role in the transportation of acids and alkalis.
