Pneumatic UPVC Flanged Diaphragm Valve is designed for reliable and automated on-off isolation and flow control of corrosive fluids in industrial piping systems. Its UPVC body provides excellent resistance to many chemicals and corrosive media, while the flanged connection offers secure installation in industrial pipelines. The pneumatic actuator enables fast, remote and automated operation, making it suitable for chemical processing, water treatment, wastewater, electroplating and other corrosive-fluid applications.

Product Specifications and Overview

ALIS Valves offers Pneumatic UPVC Flanged Diaphragm Valves for industrial applications requiring reliable flow regulation, tight shut-off and automated operation. These valves feature a UPVC (unplasticized polyvinyl chloride) body, a flexible diaphragm and a pneumatic actuator that operates the valve using compressed air. The diaphragm controls fluid flow while separating the process media from the valve’s operating mechanism, helping provide effective sealing and reduce the risk of leakage through the stem area. The flanged end connections support secure installation in compatible piping systems, while pneumatic actuation enables remote operation and integration with automated process control systems.

Pneumatic UPVC Flanged Diaphragm Valves are suitable for compatible applications in water treatment plants, chemical processing facilities, wastewater systems and industrial fluid handling installations. The UPVC body offers corrosion resistance for suitable fluids, while the diaphragm material must be selected according to the chemical composition and operating conditions of the process media. Important selection factors include fluid compatibility, operating pressure, temperature, valve size, flange standard, diaphragm material and pneumatic actuator requirements. Choosing the correct valve configuration helps support dependable flow control, reliable shut-off and efficient automated operation within the specified service conditions.

Frequently Ask Questions

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.
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.
Yes. The diaphragm can generally be replaced during maintenance without replacing the complete valve body.
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.
The diaphragm creates a barrier between the process media and internal operating components, helping protect the valve mechanism from direct exposure to the fluid.
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.
