Description
The PP Diaphragm Valve Spigots EPDM is a high-integrity flow control valve designed for reliable isolation and regulation of fluids in polypropylene pipe systems. Using a diaphragm mechanism rather than traditional seals or glands, the valve delivers bubble-tight shut-off with minimal maintenance requirements.
Manufactured from chemically resistant polypropylene, this diaphragm valve is well suited to aggressive fluids, slurries and hygienic process media. The EPDM diaphragm offers excellent flexibility and durability, with a long service life under repeated cycling. Fusion spigot ends allow direct connection to PPH pipework and fittings, creating a secure, leak-free joint.
Its simple handwheel operation, clear open/closed indication and enclosed flow path make this valve a dependable choice for demanding industrial and process environments.
