A cast steel flanged gate valve is a heavy-duty wedge gate valve for hot, high-pressure process lines. A wedge gate valve moves a wedge-shaped gate between two body seats using a spindle, so when it is fully open the fluid has a straight, uninterrupted passage with very little pressure drop. It is not recommended for flow regulation and should only be used fully open or fully closed. The maximum working temperature is 300°C and the cold working pressure is 1,960 kPa (19.6 bar) for Class 150, with flange dimensions to ANSI B16.5. The body and bonnet are ASTM A216 WCB, the wedge is WCB with 13Cr, the stem is ASTM A276 T410, the seat ring has hard-faced Stellite and the packing is graphite.
