When deciding on a direction control valve manufacturer, there are a few things to consider. If you need directional valves for more than one direction, you’ll need to choose a manufacturer with a reputation for quality. Directional valves can be used in a number of different industrial applications, including die casting, machine tooling, marine/offshore, press, primary metals, plastics, pulp and paper, and turbine control.
Fluid flow in more than one direction
Directional valves are used to control the direction of a fluid flowing through them. They are commonly referred to as bang-bang valves because they can suddenly shift from fully open to completely closed, causing fluid hammer. They can be grouped with different ports and positions or be one valve that switches flow directions. International standards refer to them as four-way valves. The name “port” has several meanings, depending on the flow conditions.
Types of directional control valves
A directional control valve is an industrial device that is used to open and close the flow of a medium. These valves typically have several ports, or spools, and are typically designated based on how many ports and switching positions are present. Generally, they have two to three working ports and at least two spool positions. One of the most common types is the 4/3-way valve, which has four working ports and three spool positions.
