A valve is a tool designed to stop and change the direction of liquid flow. A valve is a mechanical device that blocks a pipe either partially or completely to change the amount of fluid that passes through it. Banjo valves are precision molded schedule 80 polypropylene reinforced with fiberglass for durability, strength and chemical resistance. The ball of every valve is diamond turned, after molding, to make it spherically perfect, which provides precise contact between ball and seats. PTFE self-lubricating stem bushings and seats cannot stick or bind. Banjo valves come standard with EDPM gaskets and seals. They can be used in a variety of applications such as fertilizers, industrial chemicals, pharmaceuticals, textiles, and water treatment.
