Which type of valve is used if an actuator must be operated from two or more locations?

In fluid power systems, a valve that allows an actuator to be operated from two or more locations is a Direct Control Valve (DCV). This type of valve is designed to direct the flow of hydraulic fluid to an actuator based on the input from multiple control points.

When an actuator needs to be controlled from different locations, a DCV provides the necessary functionality to ensure that flow can be directed appropriately based on which control point is activated. This ensures increased flexibility and control, enabling operations from various positions within the system.

This is particularly important in applications where accessibility is crucial or where the operator may need to stop or start the actuator from different sides of a machine or area. The DCV accommodates the requirement for multiple input sources seamlessly, which is essential for efficient operation in many fluid power applications.
