Flange Check Valve What is check valve? A check valve, clack valve, non-return valve, reflux valve, retention valve or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. Check valves  are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications. Check valves are often part of common household items. Although they are available in a wide range of sizes and costs, check valves generally are very small, simple, or inexpensive. Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. The bodies (external shells) of most check valves are made of plastic or metal. Types of Check Valve ball check valve ball check valve is a check valve in which the closing member, the movable part to bloc

China Gate Valve What is Gate valves Gate valves  are widely used for all types of applications and are suitable for both above-ground and underground installation. Not least for underground installations it is paramount to choose the right type of valve to avoid high replacement costs. Gate valves are used to shut off the flow of liquids rather than for flow regulation. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low flow resistance. The size of the open flow path generally varies in a nonlinear manner as the gate is moved. This means that the flow rate does not change evenly with stem travel. Depending on the construction, a partially open gate can vibrate from the fluid flow Gate valves are mostly used with larger pipe diameters (from 2" to the largest pipelines) since they are less complex to construct than other types of valves in large sizes. Gate Valve Parts Main gate valve parts of a gate valve are: body, se

Gate Valve  plays a decisive role in various industrial productions and can control the key equipment for smooth flow of resources from various sources. The gate valve with good quality has good sealing performance, and the structure has a small flow resistance, so it can assume the responsibility of the pipeline "manager" to manage and release all liquid substances. In order to facilitate the majority of users to have a better understanding of the "quality" of the gate valve, the following  Gate Valve Supplier  will briefly explain the relevant content. DIN F4 Gate Valve Section 1: Good anti-corrosion performance The reason why the gate valve can be adapted to be used in different industries is mainly because there are high-quality materials that can effectively resist all liquid substances, whether it is corrosive acid or alkali substances or various heat and cold degrees. Substances, gate valves will not be changed in the slightest quality during long-te

It is self-evident that the excellent quality of the non-return valve can not only be the most critical element for the implementation of safety, but also the key point to ensure the optimal execution of the use requirements. Therefore, the content of the consideration in its use There will be more, only check valves that rely on excellent quality are more guaranteed during use, so how do check valves belong to the basic points of excellent quality? Swing Check Valve 1. The high standard requirements of the material meet The check valve contains many parts, and the production materials targeted by different categories will also have certain differences. Because the environment of the check valve is often used in high temperature, high pressure and other harsh environments, it is essentially a check valve. The production material requirements of the valve will also be very high. The quality assurance check valve must be im

As a  Ball Check Valve Leading Supplier , share with you. One-Way Valve: Check valve, also known as one-way valve or check valve, its role is to prevent backflow of the medium in the pipeline. The bottom valve of the water pump is also classified as a check valve. Multi-function Check Valves Check Valve: It is a valve that can actively prevent backflow of fluid. The valve flap of the check valve opens under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the pressure on the inlet side is lower than that on the outlet side, the valve flap is actively closed under the action of fluid pressure difference, own gravity and other factors to prevent fluid backflow. Check Valve: It is usually divided into several types such as lifting type, swing type, butterfly type and diaphragm type. The structure of the lift check valve is usually similar to that of the globe valve. The valve flap moves up and down along the line in the channel. The
