A control valve is used in the oil and gas industry to control the flow of liquid in a pipeline or process according to signals managed by a controller. Valves can be sealed against or with liquid flow, depending on installation requirements (p. E.g. closed error vs. open failure) and choice plays an important role by dimensioning an actuator. Like slide valves, balloon valves can be varieties of ascending stem or NRS

Instead, actuators work on flexible, generally rubber elements that open and close valve channels, eliminating the need to place metal parts in the liquid flow and associated packaging. Butterfly valves are quarter-round valves that use center-mounted round fins that balance in and out of the flow. The main specifications include port connection, valve size and materials that make up the ecozen valve body, the handlebar, seal, disc and packaging. Butterfly valves are used in sewage treatment plants, power plants and process plants for closure and for regulation and insulation, and are especially popular in large diameter pipes. Generally smaller and cheaper than a ball valve with the same capacity, butterfly valves can be difficult to operate against high pressure and flow.

For example, they can be used in commercial heating / cooling systems to adjust water temperatures under different loading conditions. They can also be used to provide a counterweight force for cylinders with two effects. The reason for the two types of ball valves has to do with how they are sealed and how the power of the liquid is distributed from the flow from the line to the ball and then to the seat. In the floating ball design, the ball drives comfortably between two seats, one upstream and one downstream.

A pinch valve uses a flexible tube that serves as a pipe, which can be closed under pressure by using air or liquid pressure against the outer surface. The main specifications are the size of the valve and the material used in the tube. In a squeeze valve, the tube itself is the only material that comes into contact with the product in the tube. Squeeze valves are used to control the flow and close food vegetables, dry products, sand, gravel and the like.

Valves are available in the smallest sizes in a wide range of plastics and are used in many laboratory applications. Ball valves are available in brass, stainless steel, polypropylene and other plastics, for example. Valves often have functions that allow quick disassembly and reassembly. Two popular valve styles that do not use metal parts that come into contact with the liquid are the membrane and pinch valves.

Gate valves are mainly used to block the flow of liquid and are used less often for flow control. A slide valve uses a plate-shaped barrier that can be lowered into the current stream to stop the current. The operation is similar to that of a balloon valve, except that the gate offers less current limitation than with a balloon valve stop when the valve is fully open.

They can work efficiently on a wide range of pressures and are ideal for high pressure applications as the fluid pressure also disappears in the stump and seat springs. Therefore, they are easier to operate with a lower working torque or a small actuator. Balloon valves are among the most popular types of valves used in different applications. These valves resemble slide valves and use linear motion to accelerate flow. They are used to control the current in a tube and control the position of a moving disk relative to the stationary ring chair.
