Frequently Ask Questions

What Is a Pneumatic UPVC Flanged Diaphragm Valve?

A Pneumatic UPVC Flanged Diaphragm Valve is an automatically operated diaphragm valve with a UPVC body and flanged connections, designed for controlling and isolating water, chemicals and compatible corrosive fluids.

What Is the Advantage of a Flanged Connection?

A flanged connection provides a secure and easily removable connection to industrial piping systems and is particularly useful where regular maintenance or equipment disassembly may be required.

Can the Diaphragm Be Replaced?

Yes. The diaphragm can generally be replaced during maintenance without replacing the complete valve body.

How Does a Pneumatic UPVC Flanged Diaphragm Valve Work?

Compressed air operates the pneumatic actuator, which moves the diaphragm to open or close the valve. The diaphragm separates the process fluid from the valve's operating mechanism.

Why Use a Diaphragm Valve for Corrosive Media?

The diaphragm creates a barrier between the process media and internal operating components, helping protect the valve mechanism from direct exposure to the fluid.

Who Is a Pneumatic UPVC Flanged Diaphragm Valve Manufacturer in India?

Alis Valves is a Pneumatic UPVC Flanged Diaphragm Valve manufacturer and supplier in India, providing corrosion-resistant automated valve solutions for chemical processing, water treatment, wastewater, electroplating, fertilizer and industrial fluid-handling applications.
