The simple control flow valve is the throttle valve. Throttling is a point the flow changes, influence the movement speed of actuators.
Component chart
The aim of component chart is to illustrate the basic operation of a valve. I provide a simple drawing instead of a representation of the actual construction, one that could find in practice. There are considerable differences in design from manufacturer to manufacturer.
The throttle direction is when fluid flows from A to B. The throttle opening is formed by the adjustment knob pin. When turned throttling opening alters. When there is flow from B to A the check valve is pushed upwards. Fluid flows without throttling to port A.
Non-adjustable -fixed – throttle are found in gauge connection to protect the device from excessive pressure surges or peaks.
Control flow in a hydraulic system is achieve by flow control valve. These valves are used to keep a set flow constant regardless of pressure variations.
Throttle valves are used, when there is a constant working resistance or a change in speed is irrelevant or even desirable with changing load. A constant working resistance in a hydraulic system means that the system must maintain a steady pressure to overcome a continuous opposing force. A hydraulic press is applying continuous force during metal forming or plastic molding. So, during the production process the hydraulic press experiences a constant working resistance e.g. when uniform shaping a metal sheet.
- The simple control flow valve is the throttle valve;
- The component chart illustrate the basic operation of a valve;
- Throttling is a point the flow changes and influence the speed of movement of actuators;
- Flow control valves will usually have maximum system working pressure at their inlet ports.
