SVR Global is the most popularControl valve manufacturer in USA. A Control valve is a valve that is used in process control to regulate the flow, pressure, or temperature of a fluid such as gas, steam, or liquid. The actuator responds to a signal from the controller by shifting the valve position to maintain the desired process variable.

Control valves are used when there is a need to maintain process parameters at desirable levels. This set of valve controller points can be flow rate, pressure, and temperature. They also provide support to the seat surface, valve closing elements, fluid static pressure, and seat.

The working principle of a control valve is very simple. A control valve in an industrial setting works by adjusting the size of an opening to control the flow of fluid through a pipeline. When the valve is fully open, the passage allows maximum flow, and when it's fully closed, it stops the flow completely. In between, it can be set so that just a known quantity of fluid will pass through. In most cases, it is automatically controlled by signals from an associated controller, such as a pressure, temperature, or flow rate sensor.

Applications:

Chemical Processing: Control valves in chemical processing plants control fluid and gas flow in chemical processing.

Oil and Gas Production: Control valves have become a ubiquitous part of the oil and gas production and process lines in their use for regulating the flow of fluids, gases, and other process variables within production.

Power Generation: It is used in power generation plants for the control of the steam and other fluids involved in the production of electricity.

Water Treatment: Control valves are used in water treatment plants to regulate the flow of chemicals and other substances used in the treatment process.

Advantages:

Control Accuracy: Control valves guarantee accurate control of the fluid flow or gas, or other process variable in a processing system so that such a system would function at optimum levels.

Energy efficiency: The fluids and gases will be controlled through control valves, so their flow will be reduced with the utilization of energy. This will reduce running costs and improve efficiency.

Safety: Applying control valves in regulating hazardous fluids or gases flow may make them safe and minimize the risk of accidents.

Low Maintenance: Control valves can be designed to serve for extended periods without failure, minimizing downtime and maintenance cost.

Flexibility: Control valves can be designed to serve the specific needs of a process, hence they can be very useful for a broad range of applications.

High-value, Non Slam Swing Check Valve Manufacturer in USA. Quality in Valves Underlies Fast Control of Flow in Diversified Application Areas. A non-slam swing check valve is so designed that it would not allow backflow by any piping system in order to eliminate water hammer produced by sudden reversal of flow. This valve gives trouble-free, noiseless operation and keeps the system free from shock, providing steady flow.

What is a Non Slam Swing Check Valve?

A non slam swing check valve is like a standard swing check valve but includes additional provisions for preventing water hammer. It comprises a swinging disk that allows flow in one direction, but it automatically closes off if the flow reverses. The non slam characteristic comes from its design that includes a damping mechanism meant to control the closure speed of the disc, which will prevent slamming it shut and consequently stopping pressure surges.

Under normal operating conditions, it allows the valve to open with flow moving forward which knocks the disc out of its seat. When the flow is reversed, the combined effect of gravity and pressure forces in the system acts to allow the disc to be moved to the closed position thereby preventing backflow. The non slam characteristic ensures that it closes slowly thus ruling out shock impacts or pressure surges that could damage the pipeline or appurtenance.

Components:

Disc

Hinge Pin

Spring (optional, for faster closure)

Seat

Bonnet
