Industrial valves or "valves" are equipment used to stop, start and regulate flow in piping systems. The most important features of valves include opening and closing the flow path (like a switch), increasing and decreasing the flow rate (regulating the flow rate), adjusting pressure, adjusting temperature, separating one part of the system from other parts (isolation), protecting the system. In critical situations, he pointed to turning the path one-way and reversing the direction of the flow.
It is one of the types of valves to adjust operational parameters in piping systems. This type of valve is used to directly adjust the flow rate and capacity. By controlling these parameters, it is possible to indirectly change dependent parameters such as temperature, pressure and liquid level. It is used in the system. Control valves are also known as "Regulating Valve".
It is a type of control valve with an electromechanical actuator that is used to block, start, measure, distribute or combine fluid flow. This type of valve benefits from high operating speed, good reliability, long life, compatibility with all kinds of materials, low energy consumption and small dimensions. Solenoid valves are used to control the fluid flow of cylinders, hydraulic motors or large industrial valves. Many mechanized irrigation systems also use these valves.
On - Off:
Most of the valves in various industries are used to open or close the fluid path and put the path in a completely open or closed state. Their flow channel type is usually Straight Way and they show less resistance to the flow of current. Considering the internal structure and the type of sealing components, these valves should not be placed in a half-open state, because by doing this, serious damage will be done to the conduit and other sealing processes of the valve, and thus its service life will be greatly reduced, and in emergency situations and Unforeseen events that need to cut off the flow, the desired valve will not perform its task properly and will cause unfortunate and sometimes irreparable events."Ball, samovar and gate lions" are included in this category. Of course, by making changes in the internal structure, they can also be used to regulate the flow.
Pneumatic Control Valve:
Pneumatic valves may be placed in a fully open or fully closed state, or become different states that can be defined, of course, the type of valve on which this device is installed is also important. The overall structure of these valves consists of It consists of a control circuit, a positioner that adjusts the state of the valve and the flow rate of the fluid, a pneumatic force generator, and finally a mechanical valve that is usually a ball or propeller. These valves have a time to open and close. They need to be considered in the design stages of the line, as well as some of them work in a single multiplication and some in a gradual way.
Hand valves are designed to connect and disconnect the flow of liquid and gas in refrigeration systems. These valves are available in two types of welding and bead connections and in different sizes.
