A ball valve is a valve with a spherical disc, the part of the valve which controls the flow through it. The sphere has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. The handle or lever will be inline with the port position letting you "see" the valve's position.

Valves are of three piece design, fitted with six set of metallic studs and nuts which contributes to their sturdy construction.
Valves have full bore; thereby, allowing full 100% flow.
Body and Stem seals are offered in various elastomers like EPDM, Neoprene, Hyplon, Butyl, Viton and also in PTFE for chemical resistance against most chemicals.
Valves with PTFE seals are provided with steel ring inserts which gives better sealing and safety features.
Steel inserts in stem and handle give more strength, sturdiness, longer life and better performance.
Carbon black resists ultraviolet rays and prevents degradation of polypropylene in sunlight exposure.
