Pressure filter is a common solid-liquid separation equipment primarily used for filtration and separation of solid particles. It operates by applying pressure to pass the solid-liquid mixture through a filtering medium, retaining the solid particles on the filter medium and allowing the liquid portion to pass through, thus achieving solid-liquid separation. In a pressure filter, valves play a crucial role.
Applications of Pressure Filter:
● Food and beverage processing
● Chemical manufacturing
● Mining industry
● Power generation
● Aggregate, asphalt, and cement production
● Steel mills
● Municipal plants

Valves In Pressure Filter Have The Following Important Functions
Feed Control
Valves are used to control the feed rate and velocity of the solid-liquid mixture, ensuring stable and uniform feed. By adjusting the valve opening appropriately, the flow rate and pressure of the feed can be controlled to meet different operational requirements.
Pressure Regulation
Valves can be used to regulate and control the operating pressure of the pressure filter. By adjusting the opening of the feed and discharge valves, the pressure inside the filter chamber can be modified to accommodate different filtration requirements.
Liquid Discharge
Valves in the pressure filter are utilized to control and regulate the speed and flow direction of the liquid discharge. Opening or closing the corresponding valves enables control over the discharge of the filtrate, ensuring efficient filtration and dewatering.
Filter Cake Discharge
Valves play a critical role in the process of removing the filter cake. Proper valve design and control enable the removal and detachment of the solid particles from the filter medium, ensuring the cleanliness and reuse of the filter medium.
There are various types of valves used in pressure filters, including pneumatic ball valves.
Pneumatic Ball Valves For Pressure Filters
Quick Response
Pneumatic ball valves are controlled by pneumatic devices, allowing for fast opening or closing of the fluid passage, enabling rapid fluid control.
Reliable And Stable
Pneumatic ball valves use a ball as the sealing element, providing good sealing performance and wear resistance, ensuring stable sealing effectiveness even in high-pressure and high-temperature environments.
Excellent Corrosion Resistance
The ball and sealing materials of pneumatic ball valves are typically made of corrosion-resistant materials, enabling them to withstand various corrosive media in the working environment.
Convenient Operation
Pneumatic ball valves are easy to operate and can be remotely controlled through pneumatic devices, eliminating the need for manual operation and enhancing work efficiency and safety.
Other Types of Valves For Pressure Filters Include
Globe Valves
Used to shut off fluid flow, they control flow by opening or closing the valve.
Safety Valves
Used to protect equipment and piping systems, safety valves automatically release over pressure fluid when the set pressure is exceeded, ensuring equipment safety.
Custom Valves For Your Application Needs
Industry, application, and operational considerations will guide specific details such as valve type, size, material selection, and other features or systems such as remote control, automated regulation, sealing performance, etc. Valve design depends on a range of factors such as fluid medium, operating pressure, temperature range, flow requirements, and many others.
