Types of industrial valves and their application in industry 
Industrial valves are used to control the flow of liquids, gases and other materials and are one of the vital components in various industrial systems. Industrial valves have different types such as gate valves, ball valves, butterfly valves, etc., each of which They have various uses in the industry. The components of industrial valves can be called gate or disk, stem and seal. In this article, we have introduced the types of industrial valves, their application, features and components. If you want to have complete information about all types of industrial valves, stay with us until the end.
Valves are used as tools for disconnecting and connecting, regulating and controlling the flow. An industrial valve is a device used to control the flow and pressure of liquids, gases and mixtures in piping systems. These valves play an important role in improving the efficiency and safety of systems by changing the direction, regulating the flow, preventing the return of the flow and controlling the pressure.
: Gate Valve
The gate valve is one of the most common types of industrial valves used to shut off and connect the flow. These valves have a gate that cuts or connects the flow by moving vertically.
Features: simple design, full flow disconnection and connection capability, high pressure resistance
Applications: oil and gas, petrochemical, water and sewage industries, power plants.
: Ball Valve
The ball valve has a ball that turns off and on the flow. These valves are very popular because of their quick and simple operation.
Features: fast performance, excellent sealing, simple design
Applications: chemical industries, oil and gas, irrigation systems, liquid transmission lines

: Butterfly Valve
A butterfly valve has a circular disc that rotates to control the flow. These valves are suitable for applications that require precise flow control.
Features: Simple design, light weight, accurate flow control
Applications: HVAC systems, food and beverage industries, marine industries, water transfer systems.
: Needle Valve
The needle valve is used to precisely control the flow of liquids and gases. These valves have a thin needle that adjusts the flow by moving gradually. Features: Accurate flow control, suitable for low and precise flows
Applications: pharmaceutical industries, laboratories, chemical industries, instrumentation systems
: Check Valve
A one-way valve is designed to only allow flow in one direction and prevent backflow. These valves are used to prevent liquids and gases from returning to the system.
Features: flow back prevention, automatic operation
Applications: pumping systems, liquid and gas transmission lines, irrigation systems
: Safety Valve
The safety valve is designed to protect systems against overpressure. These valves automatically open to release excess pressure and then return to their original state.
Features: automatic operation, system protection against overpressure
Applications: boilers, pressure vessels, hydraulic systems, chemical industries
Body: The body of the valve is its main and external part, which includes all internal components and parts. The body is made of various materials such as steel, cast iron, bronze and plastic and must have sufficient resistance to pressure, temperature and corrosion. The body must be able to withstand the pressure and high temperature of the fluid. The choice of body material must be made based on the type of fluid and working conditions.
Gate or Disc: The gate or disc is a part of the valve that is in direct contact with the fluid and is responsible for connecting and disconnecting or regulating the flow. The shape and design of this component is different based on the type of valve. Its main function is to control the fluid flow by moving vertically or rotating. The gate or disk must be made of materials that are resistant to corrosion and wear.
Stem: The stem is a rod that connects the gate or disk to the operator (handwheel) and with its rotation or movement, the gate or disk moves. The stem must withstand the fluid pressure and the force applied by the operator. and control the flow correctly by moving accurately and in coordination with the operator.

Seal or Packing: Seals are used to prevent fluid leakage through connecting the stem to the body. This component must be designed to be resistant to the pressure and temperature of the fluid. The seal is responsible for keeping the fluid inside the system and preventing it from leaking out, and it must be able to withstand harsh working conditions such as pressure and high temperature.
Actuator: Actuator or control mechanism is a part of the valve that supplies the necessary force to move the stem and gate or disc. Actuators can be manual, electric, pneumatic or hydraulic. Actuators are selected based on the type of application and system requirements. It must have reliable performance so that the valve can function properly.
Bonnet: The bonnet is a part of the valve body that is connected to it and keeps the stem in place. This component is bolted or welded to the body. The cap is responsible for protecting the internal components of the valve and keeping them in place, and it must be made of durable material to withstand harsh working conditions.
Seat: The seat is the part on which the gate or disc is placed to cut off the flow. This component must have proper sealing and be resistant to wear.
: Choosing the right industrial valve depends on several factors, including
Fluid Type: The type of fluid to pass through the valve, such as water, oil, gas, or chemicals.
Pressure and temperature: pressure and temperature of the fluid in the system.
Flow rate: the amount of fluid flow that must pass through the valve.
Actuator Type: The type of actuator required to open and close the valve, such as manual, electric or pneumatic.
Valve body material: The valve body must be compatible with the type of fluid and environmental conditions.
Dimensions and connections: The dimensions and connections of the valve must match the existing piping system.
In the repair and maintenance of industrial parts, a number of important factors should be considered so that no damage is caused to the industrial part. :The maintenance of industrial valves must also have certain requirements and criteria, including
Periodic inspection: Periodic inspection of industrial valves is necessary to ensure proper operation and prevent possible failures. These inspections should include checking the appearance, mechanical performance and correct operation of the valve.
Regular cleaning and maintenance: Regular cleaning and proper maintenance of industrial valves can increase their useful life. Cleaning of sediments and suspended particles and lubrication of moving parts are among the necessary measures in this field.
Replacement of worn parts: Timely replacement of worn and damaged parts can prevent more serious breakdowns and additional costs. It is also important to use quality spare parts in accordance with production standards.
Training and awareness: Training employees and operators on how to properly use and maintain industrial valves can help improve performance and reduce breakdowns. These trainings should include how to operate, maintenance methods and periodic repairs.
Follow instructions: Always read the valve manufacturer's instructions carefully before performing any repairs or maintenance.
Using the right tools and equipment: Use the right tools and equipment to repair and maintain valves. Using the wrong tool can damage the valve.
Use of original spare parts: Always use original and high quality spare parts. Using counterfeit spare parts can damage the valve and shorten its life.
Get help from an expert: If you are unsure about how to maintain your faucet, get help from an expert
Leaks: Leaks can occur from any part of the valve, including the stem, gland, or fittings. Leaks can cause fluid waste, environmental damage, and even safety hazards.
Corrosion: Corrosion can be caused by contact with corrosive fluids or exposure to high humidity. Corrosion can cause the valve body to weaken and eventually fail.
Abrasion: Abrasion can be caused by the constant movement of valve parts. Abrasion can cause leakage; pressure drop and reduced accuracy of the valve.
damage: damage can occur as a result of impact, impact, or other incidents. Damage can cause the valve body to break, the stem to bend, or other serious damage.
