The arc-welding process also allowed valve parts that were difficult to cast or forge to be joined together, and one of the biggest innovations was the development of weld-applied hardfacings.See all results for this questionWhat kind of welding is used to weld globe valves?An individual qualifies to weld that particular procedure via a WPQ. The gas metal arc welding process is used to overlay a globe valve disc with Inconel. The popularity of welded connections in piping systems means that valves must have the proper end connections for weld attachment.See all results for this question
What kind of wafer is used to hold valve in place?
A commonly used design is the wafer type that fits between two flanges. Another type, the lug wafer design, is held in place between two flanges by bolts that join the two flanges and pass through holes in the valve's outer casing.See all results for this questionWhat kind of disc is used in lift check valves?The disc is usually in the form of a piston or a ball. Lift Check valves are particularly suitable for high-pressure service where velocity of flow is high. In lift Check valves, the disc is precisely guided and fits perfectly into the dashpot. Lift Check valves are suitable for installation in horizontal or vertical pipe-lines with upward flow.See all results for this questionWelding and Valves Go Hand in Hand - Valve MagazineWelding and valves officially became joined at the hip with the perfection of the arc-welding process in the late 1920s. Up until then, every component in a valve was made of solid, homogeneous material, and all the end connections were either threaded or flanged.

Swing Check valve and Lift Check valve - Piping
A basic swing Check valve consists of a valve body, a bonnet, and a disk that is connected to a hinge. The disk swings away from the valve-seat to allow flow in the forward direction, and returns to valve-seat when upstream flow is stopped, to prevent backflow. The disc in a swing type Check valve is unguided as it fully opens or closes.
