Forklift Steering Valves - A valve is a device that controls the flow of a fluid like liquids, slurries, fluidized gases or regular gases, by closing, partially obstructing or opening certain passageways. Valves are usually pipe fittings but are typically discussed as a separate category. In cases where an open valve is concerned, fluid flows in a direction from higher to lower pressure.
Valves are used in many applications like for example industrial, residential, transport, commercial and military industries. A few of the major industries which depend on valves include the power generation, water reticulation, sewerage, oil and gas sector, mining and chemical manufacturing.
In daily activities, the most popular valves are plumbing valves as seen since it taps for tap water. Several common examples include small valves fitted to washing machines and dishwashers, gas control valves on cookers, valves within car engines and safety devices fitted to hot water systems. In nature, veins in the human body act as valves and control the blood flow. Heart valves even control the flow of blood in the chambers of the heart and maintain the right pumping action.
Valves could be utilized and worked in lots of ways that they could be operated by a handle, a pedal or a lever. Moreover, valves can be worked automatically or by changes in temperature, pressure or flow. These changes could act upon a piston or a diaphragm which in turn activates the valve. Several common examples of this type of valve are seen on safety valves or boilers fitted to hot water systems.
Valves are utilized in a lot of complex control systems which may require an automatic control which is based on external input. Controlling the flow through the pipe to a changing set point is an example. These circumstances generally need an actuator. An actuator will stroke the valve depending on its set-up and input, allowing the valve to be places precisely while enabling control over various needs.
