Introduction to the Structure, Performance Principle and Classification of Butterfly Valve
I. Overview of Butterfly Valves The butterfly valve is a valve with a simple structure that regulates and cuts off the flow path. Its key component is a disc-shaped butterfly disc, which is installed in the diameter direction of the pipe. The valve is opened and closed by rotating the butterfly d...Read more -
Overview of the structure of valve connection end face
The valve connection surface structure directly affects the valve sealing performance, installation method and reliability in pipeline system. TWS will briefly introduce the mainstream connection forms and their characteristics in this article. I. Flanged Connections The universal connection meth...Read more -
Valve Gasket Function & Application Guide
Valve gaskets are designed to prevent leaks caused by pressure, corrosion, and thermal expansion/contraction between components. While nearly all flanged connection’s valves require gaskets, their specific application and importance vary by valve type and design. In this section, TWS will explain...Read more -
What are the requirements for valve installation?
In the industrial and construction sectors, the selection and installation of valves are critical factors in ensuring the proper functioning of systems. TWS will explore the considerations when installing water valves (such as butterfly valves, gate valves, and check valves). First, let...Read more -
What are the inspection items and standards for butterfly valves?
Butterfly valves are a common type of valve in industrial pipelines, playing a critical role in fluid control and regulation. As part of routine maintenance to ensure their normal operation and safety, a series of inspections must be performed. In this article, TWS will outline the essential insp...Read more -
A Guide to Butterfly Valve Installation
The correct installation of a butterfly valve is crucial for its sealing performance and service life. This document details the installation procedures, key considerations, and highlights the differences between the two common types: wafer-style and flanged butterfly valves. Wafer-style valves, ...Read more -
2.0 The Difference Between OS&Y Gate Valves and NRS Gate Valves
Difference in Working Principle Between NRS Gate Valve and OS&Y Gate Valves In a non-rising flange gate valve, the lifting screw only rotates without moving up or down, and the only part visible is a rod. Its nut is fixed on the valve disc, and the valve disc is lifted by rotating the screw,...Read more -
1.0 The Difference Between OS&Y Gate Valves and NRS Gate Valves
Commonly seen in gate valves are the rising stem gate valve and the non-rising stem gate valve, which share some similarities, that is: (1) Gate valves seal through the contact between the valve seat and the valve disc. (2) Both types of gate valves have a disc as the opening and closing element,...Read more -
