MSS SP-88 Diaphragm Valve, Ductile Iron GGG40, DN32, PN16, RF

Key Specifications / Features

The MSS SP-88 Diaphragm Valve, in compliance with BS 5156, features a Weir type design with a ductile iron GGG40 body and a rubber diaphragm for reliable sealing. With a 1-1/4 inch (DN32) size, Class 150 LB, and PN16 pressure rating, this valve ensures precise flow control in industrial applications.

Weir Type Rubber Lined Diaphragm Valves are designed to significantly increase service life by ensuring the flowing media does not come into contact with the working components. This design also includes a self-draining function to prevent residue buildup, keeping the pipeline cleaner and healthier. The valve body is made from various materials such as cast iron, ductile iron, and cast steel, while the lining materials include options like glass, ETFE, PFA, PVDF, and Halar rubber, which can be specially processed based on specific requirements.
