Gate Valves Selection Guide | Engineering360

A fully closed gate valve provides good sealing due to the 360° disk-to-seal ring contact surface. Proper mating of a disk to the seal ring ensures there is very little or no leakage across the disk when the gate valve is closed. Observation of closed and open gate valve. Image Credit: TLV . Media . Gate valves can be used for liquid and gas disc for gate valveGate Valves | Babcock ValvesThe double disc gate valve has been designed to assure reliable operation under the most severe service condi- tions. Due to the special configuration and geometry of the upper wedge inclined face, any possibility of locking the disc in closed position is eliminated, even when closed quickly or subjected to severe thermal transients.Gate Valves | Double Disc | Wedge Type | TrupplyWedge Type Gate Valves have a disc that is in the shape of a wedge that seats against two inclined seats. Solid wedges are used in high flow or turbulent applications such as steam service. Solid design also minimized the vibration and chatter. Split wedge discs are more flexible and may be used where pipeline strains may distort the valve seats.
