Valves are an essential component in oil and gas operations, designed to regulate, control, or direct the flow of liquids and gases through a pipeline or system. Depending on the application, valves can isolate flow, control pressure, prevent backflow, or throttle flow rates. While gate valves are one of the most popular valves we carry, the selection goes far deeper. With so many specific needs in the industry, there are multiple types of valves, each suited to a particular task. Understanding the design and function of each can help ensure the right choice is made for every project.
Gate Valves
Gate valves are used primarily for full-on or off operations. They raise or lower a flat or wedge-shaped gate to control flow.
Mechanism: The gate moves vertically in a linear motion, controlled by a handwheel or actuator. When the gate is fully raised, it allows an unobstructed flow; when fully lowered, it stops the flow completely. This design minimizes pressure loss when the valve is open.
Applications: Gate valves are well-suited for applications requiring full shut-off or open positions, including:
- Pipeline Isolation: Ideal for shutting off flow during maintenance or emergencies.
- Oil Transport: Used in crude oil pipelines to control flow sections.
- Water Distribution Systems: For complete isolation without throttling.
While gate valves are not designed for throttling, their durability and reliability make them a go-to option for high-pressure environments.
Globe Valves
Globe valves are designed for precise flow control and are widely used in applications requiring throttling. Their spherical body and internal plug mechanism allow operators to adjust flow rates effectively.
Mechanism: The valve’s plug moves perpendicular to the seat, creating variable openings to regulate the flow. The position of the plug can be finely adjusted, providing excellent throttling capabilities.
Applications: Commonly used in scenarios where precise control is required, globe valves are ideal for:
- Chemical Processing: Regulating flow of reactive or hazardous materials.
- Cooling Water Systems: Adjusting flow rates to match operational needs.
- Fuel Oil Systems: Ensuring controlled delivery of fuel to systems.
Due to their design, globe valves can introduce higher pressure drops compared to other valve types, but their control precision outweighs this drawback in many applications.
Butterfly Valves
Butterfly valves offer a lightweight and cost-effective solution for controlling flow. They are especially beneficial in large-diameter piping systems where quick operation is required.
Mechanism: A circular disc attached to a rotating shaft serves as the closure element. When the disc is aligned parallel to the flow, the valve is fully open. Rotating the disc 90 degrees to a perpendicular position closes the valve, effectively stopping the flow.
Applications: Butterfly valves are versatile and frequently used in:
- Wastewater Systems: For isolating flow in treatment facilities.
- HVAC Systems: Controlling airflow and temperature regulation.
- Irrigation Systems: Managing water distribution efficiently.
Their compact design and ease of operation make butterfly valves ideal for situations where space and weight are concerns.
Check Valves
Check valves are designed to allow flow in one direction only, preventing backflow that can damage equipment or disrupt operations. These self-activating valves use the system’s flow pressure to open and close.
Mechanism: Check valves typically feature a hinged disc or a spring-loaded mechanism. When fluid flows in the intended direction, the pressure pushes the disc open. If flow reverses, the disc closes automatically to block backflow.
Applications: Check valves are essential for protecting systems from reverse flow and are commonly used in:
- Pump Systems: Preventing backflow into pumps during shutdowns.
- Compressor Stations: Protecting compressors from pressure surges.
- Pipeline Systems: Ensuring unidirectional flow of liquids or gases.
Different designs, such as swing check and spring-loaded check valves, offer flexibility for various operational needs.
