Pneumatic Diaphragm Valve, Ductile Iron, EPDM Lined, DN40

Key Specifications / Features

This Pneumatic Diaphragm Valve features a durable ductile iron body with a corrosion-resistant EPDM lining, ensuring reliable performance in demanding fluid control applications. Sized at DN40 (1-1/2 inch) and rated for PN10 (Class 150 LB) pressure, it comes with RF flanged ends for secure pipeline connections. Ideal for water treatment, chemical processing, and general industrial use, this valve offers efficient, automated flow control with low maintenance requirements.

The diaphragm valve is specifically designed to control non-corrosive or general corrosive media, offering a unique structure where the valve body is either unlined or lined with various rubber options to suit different working temperatures and fluid pipelines. The variety of available lining materials provides excellent corrosion resistance for various media. The diaphragm valve's construction separates the valve body and the cover with an intermediate diaphragm, ensuring that the valve cover and stem parts above the diaphragm are protected from erosion caused by the media. As a special form of globe valve, the diaphragm valve is ideal for applications requiring precise control and protection from corrosive fluids.
