Valve knowledge

Swing check valve is a check valve in which the valve disc rotates around the rocker axis in the valve body. In a pipeline system, when the valve is in normal working condition, fluid in the connected pipeline may experience reverse flow or backflow. However, the check valve operates automatically based on system conditions. When […]

Butterfly valves are crucial components in various industrial applications, providing efficient flow control and reliable performance. Among the different types of butterfly valves, the wafer type butterfly valve stands out for its unique design and cost-effective advantages. In this article, we will delve into the key aspects of wafer type butterfly valves, including their cost, installation,

Find out the most suitable valve type for your industrial requirements and guarantee peak performance with routine maintenance. 1. What is a butterfly valve? Butterfly valve can be opened and closed quickly by rotating only 90°, easy to operate, and at the same time the valve has good fluid control characteristics. When the butterfly valve

Ball valves are widely used to control the flow of liquids and gases due to their quick on/off operation, tight sealing, and durability, making them an ideal choice for many applications. Based on the number of separate valve body components, ball valves can be classified into one-piece, two-piece, and three-piece designs. This classification is determined by

Understanding how butterfly valves work is essential for engineers, operators, and maintenance teams managing fluid control systems. In this article, we’ll explore how butterfly valves operate, their key types, typical applications, and why they’re widely used across industries like chemical, water treatment, and HVAC. 1.Introduction to Butterfly Valves Butterfly valves are quarter-turn valves that are

Soft and hard sealing butterfly valves are widely used in fluid control systems where different media, temperatures, and pressure conditions apply. Choosing between the two depends on application-specific requirements, such as sealing performance, material compatibility, and durability. This guide explains the key differences in seat material, temperature tolerance, and use cases to help you make

Butterfly valve seats play a crucial role in determining the sealing performance, durability, and application suitability of butterfly valves. These seats form the primary sealing surface between the valve disc and the body, directly impacting how well the valve can control or isolate fluid flow. Among the various butterfly valve types, wafer-style butterfly valves are

The most commonly used valves are gate valves, butterfly valves, ball valves, globe valves, and check valves. Which valve should I use? What are their advantages and disadvantages. What factors should be paid attention to. How to make the right choice. Please keep watching.  1.Selection of valves and setting parts the valve used on the

Signal butterfly valve installation instructions 1、Check carefully whether the use is in line with the performance specification of signal butterfly valve. 2、Clean the inner cavity and sealing surface, do not allow dirt to adhere, do not open and close the butterfly plate before cleaning. 3、Check whether the transmission device is reliably connected with the flange
