Control valves direct flowing gas, steam, water & chemical compounds to compensate for load disturbance and regulate process variables as close as possible to desired set points.
What is Control Valve? A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level.
The range of Industrial Pneumatic Control Valves is available in sizes from DN15 to DN250, with pressure ratings up to PN100 / ANSI600, complying with EN and ASME-ANSI standards. It is equipped with a multi-spring actuator with single and double action, featuring a return to the safety position and an optional hand-wheel for manual emergency …
Almost all VACOMASS® control valves were developed and optimized especially for aeration air for the use in activated sludge tanks, grit chamber and exhaust air treatment. All of them close bubble-tight and can be combined customized with different makes and types of actuator and fulfill requirements of the advisory leaflet DWA-M 229.
The main difference between a control valve and a regulators is control valve control flow, while regulators control pressure. Learn more about regulators here. What are some Control Valve applications? Control valves are used in oil and gas production to controls the flow of liquid or gas. Oil and gas producers use High Pressure control valves ...
Abstract: In a supercharged pressure control valve apparatus of an internal combustion engine, a housing of supercharger has first and second by-pass air paths; a valve sheet formed on an end of the second by-pass air path; a rubber diaphragm having thick sealing part of convex and concave sectional shape at its outer periphery; a valve …

The valves which are mainly used to regulate the flow of fluid in hydraulic circuits are known as "flow control valves". The flow control valves are widely available in many different types according to their use. In hydraulics, flow control valves are used to control the amount of oil supplied to various parts within a hydraulic system.
In addition to the individual control valve, GEMÜ also supplies complete control systems. The valve type is then always preceded with the prefix PCS. For example, PCS 550 refers to a system solution based on the valve type GEMÜ 550. In addition to the control valve, the control system also includes the mounting kit, the appropriate controller ...
What is a control valve? A control valve is a power-operated used to regulate or manipulate the flow of fluids, such as gas, oil, water, and steam. It is a critical part of a control loop and is an example of a final control element. The Control Valve is by far the most common final control element used in industry today.
Without proper air and water control, problems such as pressure fluctuations and water hammer can occur. Nelson's 800 and 1000 Series Valves provide efficient and effective control.
A priority valve, shown in Figure 7 below, is essentially a flow control valve that supplies fluid at a set flow rate to the primary circuit, thus functioning as a pressure-compensated flow control valve. Flow in excess of that required by the primary circuit bypasses to a secondary circuit at a pressure somewhat below that of the primary circuit.
