Why Is a Valve Needed In This System?

In a Microfiltration system, valves are used for four main processes: feed control, discharge control, cleaning and flushing, and pressure regulation. Each process has different requirements for valves.

● Feed Control

Valves are used to control the flow rate and pressure of the feed liquid in the Microfiltration system. By adjusting the opening of the feed valve, the feed liquid can enter the system at the appropriate speed and pressure to avoid excessive pressure or excessive flow rate that could damage the membrane.

● Discharge Control

Valves are used to control the flow rate and pressure of the filtrate discharged from the Microfiltration system. By adjusting the opening of the discharge valve, the flow rate and pressure of the filtrate can be controlled to meet the requirements of product quality or subsequent processing needs.

● Cleaning and Flushing

Valves are used to control the flow direction and flow rate of the cleaning or flushing liquid in the Microfiltration system. By adjusting the valves, the cleaning or flushing liquid can be directed to different parts to remove contaminants or deposits from the membrane, ensuring the membrane’s optimal performance.

● Pressure Regulation

Valves are used to control the pressure in the Microfiltration system. By adjusting the valve opening, the system’s pressure can be regulated to ensure the microfiltration operation is performed at the appropriate pressure while protecting the membrane from excessive pressure damage.

Which Types Of Valves Suitable For Microfiltration Systems?

The common types of valves used in Microfiltration systems include globe valves, control valves, ball valves, and butterfly valves. Each type of valve has its own specific purpose.

● Globe Valves

Globe valves are used to control the on/off function of fluids. In Microfiltration systems, globe valves are typically used to control the opening and closing of the feed and discharge ports, as well as to shut off fluid flow during cleaning and maintenance processes.
