Polypropylene Ball Valves are made from glass reinforced polypropylene to provide strength and chemical resistance. Polypropylene Ball Valves combine the advantages of metal valves along with the more commonly used plastic valves. The seals are made from PTFE for smooth operation and sealing quality. EDPM O-rings are used to handle many chemicals and most fertilizers. Double O-rings are used in the stem area for extra sealing protection. These valves have an interlocking body and end plate which will allow easy thread connection at installation. These valves are ideal for use in industrial, commercial and domestic gardening and irrigation.
