what is industrial valve?
It plays an important role in controlling the flowing medium in the pipeline of the factory. The common medium is gas, water, oil, and various corrosive flow mediums. Commonly used gate valves are generally composed of accessories: valve body, switch sealing structure and valve cover. Industrial valves are control components in fluid conveying systems, with functions such as cut-off, regulation, diversion, prevention of backflow, voltage stabilization, shunt or overflow pressure relief, etc. Function. Valves used in fluid control systems, from the simplest shut-off valve to various valves used in extremely complex automatic control systems, have a wide variety and specifications.
What are the valve types for industrial valves?

gate
Gate valves, the most common type of valve in the industry, are valves that open by lifting the gate out of the fluid path. They are often used as shut-off valves to isolate piping systems.
When the gate valve is open, there are no obstructions in the flow path, so friction losses are minimal. Gate valves are used when linear fluid flow is required and minimal restriction is required.
These can be controlled by handwheels, pneumatic diaphragms, electric motors or piston actuators.
globe valve
Globe valves are used to regulate flow in a pipeline rather than having the “all or nothing” function of a gate valve. The globe valve is adjusted by the position of the movable disc (or plug) relative to the fixed ring seat.
The ports of the globe valve can run straight or at an angle. This type of angled feed valve is typically used for corrosive or viscous viscous fluids that tend to solidify. The outlet on the sloped supply valve faces downwards to aid fluid drainage to prevent clogging and corrosion.
needle valve
Needle valves are essentially a variation of globe valves and are used to control flow very finely. Needle valves contain an elongated tapered plug, as opposed to the larger and less precise disc of globe valves.
Butterfly valve
Butterfly valves are also designed to regulate flow, but have limited control capabilities. This is a simpler industrial valve and fitting that is easily operated by turning the handle 90 degrees. It is generally assumed that butterfly valves do not produce positive shutoff, but modern technology has facilitated the assembly of airtight shutoffs.
check valve
A check valve, also known as an NRV (check valve), only allows fluid to flow in one direction. Their purpose is to prevent backflow. There are several types of “plugs” that prevent backflow from a check valve. Ball check valves and piston check valves work by requiring a minimum inflow pressure. The return force is not enough to lift the ball or piston up to move in the other direction. In-flow swing check valves are pushed by hinged flaps that open in only one direction, ensuring that fluid cannot move backwards.
safety valve
A safety valve, also known as a safety valve, is an industrial valve and fitting that is installed to limit the pressure in a system. This type of angled supply valve is strictly used to prevent overpressure that can cause damage to the system.
There are also many industrial valves, which are not listed here. If you need valve-related knowledge, please contact us, we can answer any of your questions!

What are industrial valves made of?
Most industrial valves are constructed using grey cast iron, malleable cast iron, ductile iron, carbon steel, cast steel, stainless steel, etc.
Gray cast iron
Gray cast iron is cast iron with flake graphite, because the fracture is dark gray when broken, so it is called gray cast iron. Gray cast iron is currently the most widely used cast iron, and its output accounts for more than 80% of the total output of cast iron. Grey cast iron has good casting performance, cutting performance and wear resistance. Its disadvantage is that its strength, plasticity and toughness are lower than other cast irons.
malleable cast iron
Malleable white cast iron is a kind of high-strength and tough cast iron obtained by graphitization and annealing. It has higher strength, plasticity and impact toughness, and can partially replace carbon steel. Compared with gray cast iron, malleable cast iron has better strength and plasticity, especially better low temperature impact performance, and better wear resistance and vibration damping than ordinary carbon steel. This cast iron has a certain plasticity and toughness,
Nodular cast iron
Ductile iron is a high-strength cast iron material with very high strength, toughness and wear resistance, and its comprehensive performance is close to that of steel. At present, the application range of ductile iron is second only to gray cast iron. Ductile iron is used as the material of the butterfly valve, which has certain corrosion resistance and performance is much higher than that of the butterfly valve made of gray cast iron. The applicable medium includes steam, general gas and oil.
Carbon steel
Carbon steel (WCA, WCB, WCC) began to develop cast steel to meet production needs beyond the capabilities of cast iron valves and bronze valves. However, carbon steel valves have good overall performance and high resistance to stresses caused by thermal expansion, shock loads, and pipe deformation, so they expand their range of use to include general cast iron and bronze valve operating conditions.
cast steel
Cast steel is a cast iron alloy, which is a general term for iron-based alloys used to produce castings that do not undergo eutectic transformation during solidification. The advantages of cast steel are greater design flexibility and variability, improved overall structural strength and a wide range of weight variations
Stainless steel
Stainless steel refers to steel that is resistant to weak corrosive media such as air, steam, and water, and chemically corrosive media such as acid, alkali, and salt, also known as stainless acid-resistant steel. Generally, butterfly valves made of stainless steel have the best performance, are suitable for harsher working conditions, are more resistant to wear and have the longest service life.
How do you make an industrial valve?
Xinhui is an industrial valve manufacturer. In our opinion, the valve has few production parts, simple structure and average precision. It is a simple part in the machinery industry, but the core sealing part of the valve has particularly high requirements. The valve manufacturing process is complex and technically difficult. If you want to know the production process of industrial valves, please check the details!
Application of industrial valve
Valve application and valve market situation

The steelmaking industry focuses on the use of metal-sealed ball valves, butterfly valves and oxide ball valves, stop flash and four-way directional valves.
(9) Valves suitable for marine leveling: Accompanying the development of offshore oilfield exploitation, the amount of valves required for marine leveling is also gradually increasing. Offshore platforms need to use shut-off ball valves, check valves and multi-way valves.
(10) Valves for food and medicine: stainless steel ball valves, non-toxic all-plastic ball valves and butterfly valves are mainly used in this industry.
What is industrial valve automation ?
Valve automation refers to the use of electric, pneumatic, hydraulic or electromagnetic drive to control the valve by means other than human power. Its characteristics are: easy to use and safe; it can be controlled on site or remotely; it can control a single valve or centrally control multiple valves; it can perform simple on-off control or adjustment control; Electronic computer, which can realize programmed control. Due to the need for long-distance control, there will generally be valve signal feedback—light signal or 4~20mA signal feedback for valve control.
