directoperated

Direct operated refers to a type of valve or device where the actuator directly controls the movement of the valve stem or internal mechanism. This means there is no intermediary component, such as a pilot system or a solenoid operator, between the input signal and the final action of the valve. In a direct operated valve, the energy source, whether it be mechanical force, hydraulic pressure, or pneumatic pressure, is applied directly to move the valve. This direct connection typically results in a faster response time and simpler design compared to indirect or pilot operated systems. The flow of the medium through the valve is directly controlled by the position of the valve element. Examples of direct operated devices include certain types of manual valves, some direct acting solenoid valves, and basic hydraulic or pneumatic cylinders. The simplicity of the design can also lead to increased reliability and easier maintenance, as there are fewer components that could potentially fail. However, direct operated systems may require a higher input force or pressure to overcome the forces acting on the valve, especially in larger sizes or under high-pressure conditions.
