The end of the slide plate on the slide gate valve is sealed with an adjustable packing gland. Between the two seals is a wiper blade that ensures long seal life on the slide gate valve.Bush and Wilton also produces a broad range of diverter valves. Our gravity and conveying diverter valve line is designed for reliable operation and long life. The Bush and Wilton DG Gravity Diverters are for gravity flow applications. These diverter valves have mild or stainless steel construction with standard sizes from 4" to 12" and up to 24" custom designs. Round or square flanges can be provided. DM conveying diverters are for gravity feed, dilute or dense phase pneumatic conveyors. These diverter valves are vailable with flanged or tube connections for abrasive applications, polyurethane liners and hardened steel flaps are available. Other variations in the diverter valves line include diverting rotary valves, slide box diverter valves, plug diverter valves and double slide gate diverter valves.Inline pinch valves offer a smooth internal profile suitable for powders, granules, slurries, liquids and gases in gravity, pressure and vacuum conveying ducts and pipelines. They are easily installed and require minimal maintenance. The hand operated anviltype piston on a pinch valve closes a reinforced rubber sleeve by pinching it, while compressed air or suitable fluid accomplishes a bubble-tight seal on a heavy duty elastomer sleeve in the pneumatic version.
