Sanitary Valves - Butterfly, Ball, Check - 298V
Ball valves can be used for positive, quick, frequent 'on' and 'off' service or for throttling. The handle can be quickly opened or closed (90° turn) and allows for easy identification from a distance of valve position. Due to quick on and off, there is a risk of water hammer or shock if the valves are closed too quickly. When the flow is abruptly stopped, the energy in the medium hits the valve and reverberates through the line. This can damage the piping system. Whereas multi-turn valves (such as Gate or Globe Valves) close slowly, eliminating the water hammer.
