Check Valve. The simplest DCV (Direction Control Valve ) 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. Figure shows the graphical symbol of a check valve along with its no-flow and free-flow directions.

Hydraulic valves are mechanical equipment for controlling the flow of fluid in hydraulic pipes or systems. They can be utilized to thoroughly check the flow level to a specific domain, redirect pressurized fluid or close a line. Hydraulic valves can be used to control the flow of fluid in a circuit as well as the quantity of fluid power.

Check Valve – CV These seat type valves allow free flow in one direction and offer leak free closure in opposite direction. Available as inline mounting,

The purpose of a check valve is to permit free flow in one direction and prevent any flow in the opposite direction. • Fluid flows through the valve in the space between the seat and poppet. • A light spring holds the poppet in the closed position. In the free-flow direction, the fluid pressure overcomes the spring force at about 5 psi.

Poppet check valve Figure 1.3 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 .

These valves allow free flow in one direction and prevent flow in the reverse direction. Cracking pressure specified is the pressure required to open the valve 

Series F flow control valves from Pioneer allow the end user to utilize the color-band reference on the valve stem as a great convenience and time-saver when resetting the valves. The Series N needle valves have the same Colorflow feature and are ideal as speed controls on hydraulic and pneumatic circuits where a reverse flow check is not needed.

Check valves are also a major component in hydraulic processes which saves your system against a very costly shutdown. They are used for flow, directional, and pressure control. They are critical in preventing pressure build-ups and fluid restrictions, which can lead to system failures.
