Weir Type Diaphragm Valve Unlined Screwed BSPP

Description
This screwed BSPP weir-type diaphragm valve is ideal for compact and lower-pressure systems where threaded connections allow easy installation and removal. The unlined valve body and elastomer diaphragm provide effective flow isolation without the need for metal seats, reducing wear in services with particulates or slurries. It is particularly well suited to water treatment, chemical dosing, compressed air, and general industrial process applications.
