Flow meter valve group: front and rear cut-off valves are installed before and after the flow meter, and bypass valves are used to bridge the front and rear cut-off valves. The front and rear cut-off valves use stop valves or gate valves, and the bypass valve uses a throttle valve to accurately adjust the flow.…

The throttle valve is an important hydraulic control component that can control the movement speed of the actuator by changing the flow rate of the liquid. This valve is widely used in many industrial fields, including machine tools, engineering machinery, aerospace, plastic machinery and metallurgical equipment. This article will introduce in detail the application and role of throttle valves in …

Differences and differences between pressure reducing valve, safety valve, pressure stabilizing valve and pressure relief valve…

At first, Teflon in a narrow sense (Teflon: Chinese translation homophonic Te Iron F Fluorine Lon Dragon) was a trademark of DuPont, used for a series of fluoropolymer products based on polytetrafluoroethylene (PTFE). Polytetrafluoroethylene is a synthetic polymer compound formed by the polymerization of tetrafluoroethylene and is known as the "King of Plastics" for its excellent performance. Nowa…

1. Surface treatment: Clean, polish, degrease and other treatments on the valve surface to remove surface dirt and impurities, improve surface flatness and roughness, and facilitate the adhesion of subsequent coatings. 2. Coating protection: Apply a layer of corrosion-resistant coating, such as epoxy resin, polyurethane, etc., on the surface of the valve to form a protective film to block the …

Cast iron valves are usually made of high-quality gray cast iron or ductile iron, which have good mechanical properties, wear resistance and corrosion resistance. Cast iron valves have a long service life at normal temperature and pressure, and have low requirements for fluid media, and can adapt to a variety of environments and usage scenarios.…

The control valve is an important component of the industrial automation control system and is widely used in various industrial process controls. However, when the control valve is stuck or blocked, it will affect the normal operation of the control system and even cause equipment damage. Therefore, understanding the causes and treatment methods of the control valve getting stuck or blocked is of…
