In industrial production, drain valves play a critical role by eliminating condensate and superheated steam from pipeline systems to maintain normal operation. However, during cold winters, the moisture in pipeline systems is prone to freezing, resulting in the failure or damage of drain valves, thereby affecting the normal operation of the system. Therefore, implementing effective anti-freezing m ..read more

The tilting disc check valve and common check valves both serve the purpose of preventing backflow of the medium in pipeline systems, but they have differences in structural design and working principles. This article will compare and discuss the differences between the tilting disc check valve and common check valves. Structure Design Tilting Disc Check Valve: The disc of the tilting disc check v ..read more

The fully welded ball valve and the ordinary ball valve have significant differences in structure, characteristics, and applications. 1. Structural Differences Fully Welded Ball Valve: The fully welded ball valve adopts a fully welded structure, with no gaskets between the valve body and valve body, and is welded as a whole. This eliminates the need for gaskets or packing typically required in tra ..read more

The sealing surface of the valve is often corroded, eroded, and worn by the medium, making it a vulnerable component of the valve. For example, automatic valves such as pneumatic ball valves and electric butterfly valves have frequent opening and closing and fast opening and closing speeds, and their quality directly affects the service life of the valve. The basic requirement for valve sealing su ..read more

There are some differences in the structure and working principles between the angle-type bellows sealed globe valve and the bellows globe valve, primarily evident in the following aspects: Structural Design Bellows Globe Valve: Primarily utilizes bellows as the sealing element, a flexible metal conduit capable of adapting to the bending and expansion of pipelines to ensure the valve's sealing per ..read more

There are some differences in structural design and application scenarios between angle globe valves and ordinary globe valves. The following are the main differences between them: Structural design Ordinary globe valve: usually adopts a straight through structure, with the valve body and pipeline axis basically parallel. Valves can be opened and closed by lifting or rotating to cut off or control ..read more

Ball valves, as a common fluid control equipment, play an important role in the industrial field. In the classification of ball valves, fluorine lined ball valves and ordinary ball valves are two common and significantly different types. This article will explore the differences between them to help readers better understand when to choose fluorine lined ball valves or ordinary ball valves. 1. Mat ..read more

The main difference between the double jacket gate valve and the ordinary gate valve lies in its special double jacket structure. This structure allows the double jacket gate valve to operate over a broader temperature range and provides more precise control over the fluid temperature. Here are some key distinctions: Double jacket structure Double Jacket Gate Valve: Features a dual-layer jacket st ..read more

Valves used underground are mainly used in pipeline systems to control the flow, pressure, and direction of fluids. Different types of valves have different functions and uses in underground applications. The following are some common types of valves used underground: Gate Valve: Gate valve is a common type of valve, typically used for fully open or fully closed applications, rather than for regul ..read more

Butterfly valve, also known as flap valve, is a simple regulating valve that can be used for switching control of low-pressure pipeline media. Butterfly valve refers to a type of valve in which the closing element (disc or disc) is a disc that rotates around the valve axis to achieve opening and closing. Butterfly valves can be used to control the flow of various types of fluids such as air, water ..read more
