Manifold ball valves are bolted polypropylene valves reinforced with fiberglass, available in standard and full port sizes from 1" to 3". These valves use stainless steel hardware, self aligning diamond turned balls with PTFE seats, self lubricating stems and FKM seals. Ideal for chemical processing, industrial fluid systems and manifold installations, they deliver reliable flow control, corrosion resistance and flexibility through multiple configurations.
