The wafer end DPCV is sandwiched between two pipeline flanges using long bolts that pass-through both flanges and circumference of the valve body. Most compact and lightweight design than flanged end and lug end DPCV. This is a significant advantage for installations with space or weight constraints. Requires precise alignment during installation to ensure proper sealing between the valve and the flanges. Installation is generally simple and quick. For maintenance, the entire line must be shut down and disassembled to remove the valve. Best suitable for low to medium-pressure applications, as the clamping force from the flange bolts is less secure than integrated flanges for high pressures. Wafer end DPCV has Lowest initial cost due to its minimal body material and simplified design. Also cheaper to transport and install. Sealing is reliable for low- to medium-pressure applications, but its durability is limited by the bolt tension holding the flanges together.
