A valve is a module, which is able to control or regulate the flow in a pipeline by obstructing the flow within the pipe either completely or partially. There are different types of valves; each is designed to be utilized in different applications.
This valve is designed with a small port having a threaded needle similar to a plunger. This allows for precise regulation of the flow. They are utilized to check the flow of substances namely gas or water across, the system. These components are widely used in several applications, which feature carburetors. They are also seen in various water heaters, which help in regulating pressure in different devices. This helps to keep a check on the efficiency and ensures optimum usage in the system. In certain cases, they are also seen in vacuum systems to control the supply of gases through the elements.
These components are designed to accurately control the rate of flow of clean gasses and fluids. The adjustments within the system are smooth, gradual and can act as a highly reliable shut down valve. They are widely used in regulating low-pressure rates. These components exhibit a larger pressure drop from the inlet back to the outlet. Their common port sizes range between 1/8 to 2mm.
These components can be operated either manually or automatically. A manually operated element can be operated using a hand wheel, which helps in controlling the distance from the plunger back to the valve seat. This system allows the passage of fluids to be opened and closed easily. An automated system is connected to the air actuator or a hydraulic motor. This facilitates the opening and closing of the valve. The motors or actuators will adjust their position based on timers or the external performance of the element. Both these modules help in maintaining a precise and controlled flow rate within the system.
These valves open and close due to an orifice, which has a tapered end. This handle raises and lowers the element. In a manual system when the handwheel is turned in a direction, the plunger is lifted and the fluid is allowed to pass through it. It is closed by turning it in the other direction. For automatic systems, the motors lift the valve based on set timers or by checking the external performance of the machinery.
The valves in this range are bi-directional which, allows them to be rotated in any direction to control the flow characteristics. A threaded stem allows the movement of the fluid through the valve in different directions.
These components are highly reliable and used across various systems. The selection of these valves is an important criterion, which will help in enhancing the performance of the entire system. Below are some of the criteria required for selecting the best modules.
Installing these components is a simple process. Below are a few steps to follow during the installation process.
No, they can be easily moved in any direction to control the characteristics of the flow.
