Tips For Selecting The Valve For EDI Ultra-pure Water Equipment

What is EDI Ultra-pure Water Equipment?

EDI ultra-pure water equipment is a type of equipment used for producing high-purity water, with EDI standing for Electrodeionization. It removes ions and impurities from water through the action of ion exchange membranes and electrolyte solutions, resulting in high-purity water.

EDI ultra-pure water equipment is widely used in various industries, including pharmaceuticals, electronics, chemicals, and laboratories. In the pharmaceutical industry, high-purity water is an important raw material for manufacturing drugs and injections, and EDI ultra-pure water equipment can provide high-purity water that meets pharmacopoeial requirements. In the electronics industry, high-purity water is used for semiconductor production and cleaning electronic components, and EDI ultra-pure water equipment can provide low ion content water to ensure the quality and reliability of electronic products. In the chemical industry, high-purity water is used for chemical reactions and solvent preparation, and EDI ultra-pure water equipment can provide purified water source. In laboratories, high-purity water is used for experiments and analysis, and EDI ultra-pure water equipment can provide high-quality laboratory water.

Why are Valves Important?

Valves play a crucial role in EDI ultra-pure water equipment. They control the direction, pressure, and flow rate of the fluid, ensuring the proper operation of the equipment and the production of high-quality water. Different types of valves are suitable for different fluid control requirements. Globe valves are used for opening and closing fluid channels,while butterfly valves are suitable for large diameter flow control scenarios, such as flow control in industrial pipeline systems. In the context of EDI ultra-pure water equipment, butterfly valves are commonly used for inlet and outlet control, especially in large diameter water flow channels.

Types of Valves Suitable for EDI Ultra-pure Water Equipment

● Gate Valve

A gate valve is a type of valve used to open and close fluid channels. It is characterized by its simple structure, good sealing performance, and low flow resistance. It controls the flow of fluid by raising or lowering the valve gate, which provides a good seal between the gate and the valve seat. Gate valves are suitable for scenarios that require frequent opening and closing of fluid channels, such as flow regulation and fluid shut-off. In EDI ultra-pure water equipment, gate valves are commonly used for inlet and outlet control, to open and close water flow channels, and regulate flow.

● Ball Valve

A ball valve is a type of valve that controls fluid flow by rotating a ball inside the valve. It is known for its simple structure, easy operation, and good sealing performance. The flow of fluid is controlled by the angle of rotation of the ball, which provides a good seal between the ball and the valve seat. Ball valves are suitable for scenarios that require quick opening and closing of fluid channels, such as flow regulation and fluid shut-off. In EDI ultra-pure water equipment, ball valves are commonly used for inlet and outlet control, to open and close water flow channels, and regulate flow.

● Butterfly Valve

A butterfly valve is a type of valve that controls fluid flow by rotating a disc or butterfly plate. It is characterized by its simple structure, easy operation, and low flow resistance. The flow of fluid is controlled by the angle of rotation of the disc, which provides a good seal between the disc and the valve seat. Butterfly valves are suitable for large diameter flow control scenarios, such as flow control in industrial pipeline systems. In EDI ultra-pure water equipment, butterfly valves are commonly used for inlet and outlet control, especially in large diameter water flow channels.

Points to Consider When Selecting Valves

● Fluid Properties

Understand the properties of the fluid, such as temperature, pressure, viscosity, and corrosiveness, and determine the material requirements for the valves. Different fluids may require valves made from different materials. For example, stainless steel valves with good corrosion resistance are suitable for acidic and alkaline liquids, while copper valves are suitable for non-corrosive liquids like water.

● Temperature and Pressure

Select valves that can withstand the corresponding temperature and pressure requirements of the fluid. The pressure resistance capability of the valves is an important indicator, and it must be ensured that the valves can withstand the pressure of the fluid to avoid leakage or damage.

● Flow Rate Requirements

Choose the appropriate valve size based on the flow rate requirements of the fluid. The diameter and flow channel design of the valve will affect the flow rate and velocity of the fluid, so it is necessary to select the appropriate valve based on specific flow rate requirements.

● Sealing Performance

The sealing performance of the valves is crucial for preventing leakage. The sealing material and sealing structure of the valves determine their sealing performance. It is necessary to select valves with good sealing performance to ensure fluid control and prevent leakage.

● Operating Mode

Select the appropriate valves based on the operating mode of the equipment. Valves can be manually operated, electrically operated, or pneumatically operated. Choose the suitable operating mode according to the specific requirements.

Summary

Valves play a critical role in EDI ultra-pure water equipment, ensuring the smooth operation and high-quality water production of the equipment. Selecting the right type and quality of valves can ensure the stable operation and long-term reliability of the equipment.
