Cast Iron Remote Control Float Ball Valve
Electromagnetic valves are automation basic components used to control fluids and belong to actuators; Not limited to hydraulic, pneumatic. Electromagnetic valves are used to control the direction of hydraulic flow, and mechanical devices in factories are generally controlled by hydraulic steel, so electromagnetic valves are used. The working principle of an electromagnetic valve is that there is ...
Globe valve, also known as shut-off valve, belongs to the forced sealing type valve and is a type of shut-off valve. There are three types of connection methods: flange connection, threaded connection, and welded connection. The "Three Modernizations" of valves in our country once stipulated that the flow direction of globe valves should be from top to bottom, so there is directionality during ins...
Ball valve is a common type of valve, and its design characteristics make it widely used in various industrial applications. Ball valves are favored for their simplicity, reliability, and ease of operation, playing an important role in fluid control. The main components of a ball valve include a sphere with a diameter and inlet and outlet pipes located on both sides of the sphere. Spheres are usua...
At present, the commonly used hardening processes for the surface of metal hard sealed ball valves mainly include the following: (1) Surface welding (or spray welding) of hard alloy on the sphere can achieve a hardness of over 40HRC. The process of surface welding of hard alloy on the sphere is complex, with low production efficiency, and large area welding can easily cause deformation of the part...
Pneumatic valve is a type of valve driven by compressed air, which has the advantages of high efficiency, safety, and environmental protection, and is widely used in industrial automation control systems. Pneumatic valves consist of three parts: pneumatic actuator, control accessories, and valve body. The pneumatic actuator is the part that realizes the opening and closing action of the valve, whi...
The working principle of pneumatic expansion butterfly valve is to rely on compressed air provided by the air source to cause elastic deformation of the sealing pair inside the valve body, thereby achieving switch control. After the gas source enters the valve body, it is compressed to a certain pressure through a compressor and then sent into the cylinder, causing the piston to move left or right...
There are various types of regulating valve structures, each with its own characteristics. In engineering design, it should be determined based on factors such as on-site conditions (temperature, pressure, flow rate, pressure difference, installation position, etc.), fluid properties (viscosity, corrosiveness, saturation temperature, etc.), requirements of the regulating system (adjustable ratio, ...
Bellows globe valve, also known as bellows sealed globe valve, is designed with automatic roll welding to form a metal barrier between the fluid medium and the atmosphere, ensuring zero leakage of the valve stem. The internal structure of the bellows globe valve adopts a bellows structure, and the lower end of the stainless steel bellows is welded to the valve stem to prevent process fluid from co...
How to choose valve plasma welding equipment? Background of valve overlay welding Scratches, erosion, and corrosion can all damage the valve sealing surface. The composition and metal structure of sealing materials, surface treatment process, hardness and hardness difference, specific pressure and conformity, and many other factors can all affect the quality of valve sealing surfaces. Each type of...
