The simplest DCV is a check valve. A check valve allows flow in one direction, but blocks the flow in the
opposite direction. It is a two-way valve because it contains two ports
provides two schematic drawings showing the operation of a poppet check
valve. A poppet is a specially shaped plug element held on a valve seat by a light spring.
Fluid flows through the valve in the space between the seat and poppet. In the free flow
direction, the fluid pressure overcomes the spring force. If the flow is attempted in the
opposite direction, the fluid pressure pushes the poppet in the closed position. Therefore,
no flow is permitted.
