In industrial fluid control systems, butterfly valves are widely used in petroleum, chemical, power, metallurgy, water treatment and other fields due to their simple structure, small size, light weight, easy operation and low flow resistance. According to the difference in the connection mode between the valve stem and the disc, butterfly valves are mainly divided…
Stainless steel check valve is mainly made of stainless steel, used to prevent backflow. It has high corrosion resistance and strength, and is suitable for various industrial environments. This kind of valve usually has a compact shape and adopts a built-in spring structure, and can be installed vertically or horizontally in the pipeline system to…
What is a water well pump check valve? A water well pump check valve is a one way valve used to prevent the backflow of water, mainly installed at the outlet of the water well pump. Its main function is to ensure that water can only flow in one direction and prevent water from flowing…
The brass one way check valve is made of high-quality brass material, which has excellent hardness, strength, and ductility, with the size raging from 1/2″ to 4 inch. The sealing surfaces of its valve seat and valve disc are also made of copper material, and a soft-to-soft sealing method is adopted, ensuring an excellent sealing…
The vacuum swing check valve is mainly composed of a valve body, a valve cover, a valve disc and a rocker. It may also include an auxiliary spring and a weight structure to improve the sealing performance. Its internal passage is streamlined, with relatively small flow resistance, and it is suitable for large-diameter scenarios with…
Ⅰ.What is a swing check valve? The swing check valve is an automatic valve that realizes one-way flow control through the rotation of the valve disc around a pin. It is widely used in fields such as petroleum, chemical engineering, power, and water treatment. The following is a detailed analysis of its operation principle, structures,…
What is the function of the air compressor check valve? The compressor check valve is a kind of one way valve that prevents the reverse flow of gas.Its main function is to prevent the gas from flowing backward after the compressor stops operating, and thus avoid causing damage to the components of the compressor so…
When selecting a check valve for a sewage lifting device, should you choose a plate check valve or a ball check valve? Let’s explore the characteristics, advantages, and disadvantages of these two types of check valves. Functions of check valves. First, check valves have three main functions: Characteristics of plate check valves. The plate check…
In a fire protection system, a jockey pump foot valve plays a crucial yet often under-the-radar role. To understand its significance, we need to first look at the context of the jockey pump itself. A jockey pump is an essential component within a fire protection system. Its primary function is to maintain the required pressure…
In industrial product procurement, both swing check valves and wafer check valves play important roles, but there are significant differences between them. The main differences between swing check valves and wafer check valves are as follows: Structure. Swing check valves: They have a hinged disc that swings open to allow forward flow and closes under…
The axial flow check valve is a specially designed valve. The opening and closing of the valve disc are operated by the pressure difference between the inlet and the outlet end of the valve. It can effectively prevent the backflow of the medium and ensure the safety of the pipeline. This design aims to solve…

A non slam check valve is a check valve non slam type that can prevent the slam or water hammer when the valve closes. Because the non slam check valve is equipped with a special pressure reducing device. Before the valve closes, it can quickly reduce the liquid pressure inside the pipeline to below the…
What is a check valve? A check valve, also known as a non-return valve or one-way valve, is an important type of valve in fluid systems. The following is a detailed introduction: 1.Structure In terms of structure, the check valve can be devided into three types: lift check valve, swing check valve and butterfly check…
The relationship between regenerative turbine pumps and valves is mainly reflected in their interdependence and coordination in industrial applications. The regenerative turbine pump is a high efficiency vacuum pump that accelerates gas molecules out of the vacuum chamber through a high speed rotating turbine to achieve a high vacuum effect. This pump is usually…
