Vertical check valve

Vertical check valve

The functions affected by the check valves have been shown on many aspects for a variety of industries. And the basic designs of the popular check valves can be classified into three types. They are the swing check valves, lift check valves and horizontal and vertical check valves. Therefore, plenty of the check valves can be regarded as the vertical check valves.

The vertical check valves are for handling corrosives and high-purity fluids. They are extremely effective in preventing back-pressure or backflow. And it should be mentioned that the small pressure difference is able to do the operation.

Generally speaking, the vertical check valves are manufactured within various size ports for maximum capacity. The full pipe diameter ports would provide minimal obstruction in the flow path. The poppet-type design of the vertical check valves eliminates problems that occur in some check valves with pockets that can trap fluid. In most cases, the vertical check valves are used on suction system fuel lines to maintain prime through being installed directly below the dispenser pumping unit.

Moreover, the vertical check valves are less likely to need maintenance if the every surface in contact with the fluid is made of or covered with a thick layer of plastic. Therefore, the corrosion and contamination are virtually eliminated.
