Gate Valve API 602
A gate valve is a type of valve that regulates fluid flow through a disc inside it. Available in a variety of styles for use in various installations, gate valves ensure complete sealing and safety when properly selected and installed for the installation and fluid. The API 602 Gate Valve, which we sell as ORFA Industrial Products Industry and Trade Inc., is manufactured in accordance with American Petroleum Institute (API) standards and is specifically designed for use in the oil and gas industries.
Advantages of Gate Valve API 602
Bidirectional Flow Control: API 602 gate valves provide bidirectional flow, regulating fluid flow in both directions of the installation.
Low Flow Resistance : Provides easy and smooth passage by creating a low resistance environment for fluids.
Full Sealing: Provides perfect sealing in fully open or fully closed position.
High Pressure and Temperature Resistance: It can be used safely in industrial facilities with its structure resistant to high pressure and temperatures.
Compliance with API Standards: Manufactured in accordance with American Petroleum Institute standards, ensuring reliability and longevity.

Flow Control and Full Open/Closed Positions
The most distinctive feature of gate valves is that the spool only operates in either the fully open or fully closed positions. This means the valve cannot be used in intermediate positions. Using the spool in intermediate positions can cause wear on the sealing rings and impair the valve's functionality. Therefore, gate valves are not used in applications requiring precise flow control, but rather in applications where fully open or fully closed flow conditions are required.
High Pressure and Temperature Resistance
API 602 high-pressure gate valves are used in applications requiring high pressure and temperature resistance. This durability is achieved through the use of materials and design features:
Basic Working Principle
The basic operating principle of API 602 gate valves is based on controlling fluid flow with a vertically moving slide. When the valve is closed, the slide completely blocks fluid flow, ensuring a perfect seal. When the valve is opened, the slide moves upwards, allowing fluid flow. This movement is achieved through the coordinated operation of the following components:
Gate: The main moving part of the valve and can be either single-piece or multi-piece. The gate moves vertically within the valve and controls fluid flow.
Sealing Rings (Seats): The slider has two sealing rings that it seats on when closed. These rings are made of high-pressure and temperature-resistant materials to prevent fluid leakage.
Body and Bonnet: The valve body and bonnet protect the spool and other internal components. The body is typically made of forged steel, while the bonnet is made of similarly durable materials.
Flow Control and Full Open/Closed Positions
The most distinctive feature of gate valves is that the spool only operates in either the fully open or fully closed positions. This means the valve cannot be used in intermediate positions. Using the spool in intermediate positions can cause wear on the sealing rings and impair the valve's functionality. Therefore, gate valves are not used in applications requiring precise flow control, but rather in applications where fully open or fully closed flow conditions are required.
Fully Closed Position: The spool is fully down and seated against the sealing rings. In this position, fluid flow is completely blocked, ensuring a leak-proof valve.
Fully Open Position: The spool is fully up, allowing fluid to flow freely. In this position, flow resistance within the valve is minimal, and fluids can flow with minimal pressure loss.
High Pressure and Temperature Resistance
API 602 high-pressure gate valves are used in applications requiring high pressure and temperature resistance. This durability is achieved through the use of materials and design features:
Material Selection: ASTM A105N forged steel body and bonnet enable the valve to withstand high pressures and temperatures. Additionally, the stainless steel disc and Stellite 6-coated sealing rings provide long-lasting resistance to wear and corrosion.
Design: The valve design is optimized to ensure sealing even under high pressure. This ensures safe and effective operation of the valve .
Areas of Use
API 602 Gate Valves are ideal for controlling liquid or gaseous fluids and are widely used in a variety of industrial applications. They are particularly preferred in:
Oil and Gas Sector: It can be used safely in oil and gas facilities due to its compliance with the API 602 standard.
Chemical Industry: Suitable for the safe and effective transport and storage of chemical substances.
Power Generation Facilities: It is widely used in power generation facilities due to its high pressure and temperature resistance.
Water and Wastewater Management : It is preferred in water and wastewater management systems because it provides low flow resistance and complete sealing.
