P id knife gate valve symbol.

Three symbols shown below are the gate valve symbols used in isometric drawings. Epoxy coated to help resist corrosion these blowoff valves feature a rugged stainless steel seat and disc hardened to 60 rockwell c for superior service in harsh environments. Normally closed gate valve. Now see the p id symbol for the gate valve.

It is a modification of a generic valve symbol by inserting a vertical line between two triangles. Carbon steel gate valves fnpt. Isometric drawing symbols for valves. Used for high flow capacity.

316 stainless steel flanged heavy duty metal seat handwheel handle 1 piece knife gate valve. Normally closed ball valve. The first is for butt welding ends second is for flanged end valve and the third one is for socket end connection. Buttweld y type valve.
