Types of Valve Accessories

Valves play a crucial role in controlling the flow of various substances in different industries. They are used to regulate the movement of fluids such as oil, gas, water, and chemicals. However, to enhance the effectiveness and performance of valves, the use of valve accessories becomes vital. Valve accessories are components that complement the functionality of valves, making them more reliable and efficient. In this article, we will explore the different types of valve accessories and their importance in industrial applications.


Globe Valves


One widely used type of valve accessory is the globe valve. Stainless steel globe valves are designed with a globe-shaped body and a baffle which controls the flow of fluid through the valve. These valves are primarily used to start, stop, and regulate the flow of liquid in a pipeline. With their effective flow control mechanism, globe valves ensure efficient operation by minimizing pressure loss and preventing leakage. They are commonly employed in water treatment plants, power generation facilities, and chemical processing plants for their reliable performance.


Check Valves


Another essential valve accessory is the check valve. Check valves, also known as non-return valves, are designed to allow fluid to flow in one direction only. These valves prevent the backflow of liquid, ensuring that the flow remains unidirectional. Types of check valves are crucial in preventing damage to pumps, valves, and other equipment caused by reverse flow. They also help maintain the integrity of pipelines and prevent water hammer, which can be detrimental to the system. Check valves are widely used in industries such as oil and gas, water supply, and wastewater treatment.


Discharge Valves


In industrial applications where pressure relief is essential, discharge valves are employed as valve accessories. These valves are specifically designed to discharge excess liquid or gas from a system when the pressure exceeds a predetermined level. By releasing the excess pressure, discharge valves protect equipment from potential damage and ensure the safety of the system and personnel. They are commonly used in pressure vessels, piping systems, and industrial boilers. Discharge valves are available in various configurations to accommodate specific pressure requirements and flow rates.


Other Valve Accessories


Apart from globe valves, check valves, and discharge valves, there are several other valve accessories that enhance the performance and functionality of valves. Some of these accessories include valve positioners, valve actuators, pressure relief valves, and valve locks. Valve positioners are used to precisely control the position of the valve, ensuring accurate flow regulation. Valve actuators provide the necessary force to open and close valves, eliminating the need for manual operation. Pressure relief valves automatically release pressure when it exceeds a safe level, preventing system failure. Valve locks are used to secure valves in a certain position, preventing unauthorized or accidental operation. These accessories are essential in ensuring the reliable and efficient operation of valves in various industries.


In conclusion, valve accessories are crucial components that complement the performance of valves in industrial applications. Globe valves, check valves, discharge valves, and various other accessories play a significant role in enhancing the functionality, reliability, and safety of valve systems. Whether it is controlling the flow direction, preventing backflow, relieving excess pressure, or ensuring precise regulation, valve accessories are indispensable. Choosing the right valve accessories, such as those manufactured by Weidouli Valves, can greatly enhance the efficiency and longevity of valve systems.
