Functions of Pipe Valves

Stopping and starting a fluid flow. Depending on whether a valve is open or closed, it lets pass the process fluid or halt the fluid.

 

Throttling the fluid flow . Some of the valves let you throttle the fluid depending open % of total opening. Lesser the opening higher the throttling and otherwise.

 

Controlling the direction of a fluid flow. Multiport valve lets you decide the way fluid will go.

 

Regulating a flow or pressure within the piping system. Some of the automatic control valves maintain the flow and pressure within the system by adjusting opening and closing.

 

Relieve pressure or vacuum from the piping system and equipment. Pressure and vacuum relief valves safeguard the process system from overpressure and during vacuum conditions.

 

Types Of Pipe Valves
 

Gate Valve: A gate valve is used to control the flow of fluids such as liquids or gases in a pipeline. It is designed with a gate or wedge-shaped disc that slides back and forth within the valve body to control the flow of the fluid. When the gate is in the fully open position, the fluid flows through the valve with minimal resistance, and when the gate is fully closed, the flow is completely blocked. Gate valves are commonly used in applications where a full flow or no flow of fluid is required, such as in the water supply, oil and gas, chemical, and power generation industries. They are also preferred in applications where a tight shut-off is required.

 

Ball Valve: A ball valve is a type of valve that uses a hollow, perforated ball to control the flow of fluid through a pipeline. The ball has a hole or port in the center that allows the fluid to pass through when the valve is open. When the valve is closed, the ball is rotated so that the hole is perpendicular to the flow path, blocking the flow of fluid. Ball valves are commonly used in applications where a full flow or no flow of fluid is required, and where quick and easy operation is important. They are often preferred over gate valves in applications where the valve will be frequently operated, as they require less force to operate and are less likely to become stuck or jammed.

 

Butterfly Valve: A butterfly valve is designed with a disc or plate that is mounted on a central shaft, which rotates to control the flow of fluid. The disc is positioned parallel to the flow when the valve is fully open, and perpendicular to the flow when the valve is fully closed. Butterfly valves are often preferred over other types of valves in applications where space is limited, as they require less space to operate than other valves. Butterfly valves are also known for their low-pressure drop and high flow capacity, making them ideal for large-diameter pipelines.

FAQ

 

Q: What is the difference between a parallel disc gate valve and a wedge gate valve? How do I choose?

A: Parallel disc gate valves use flat, parallel sealing faces, making them suitable for media containing particles or prone to scaling. Wedge gate valves use angled sealing faces for a tighter seal but are more susceptible to damage from impurities. Selection depends on media cleanliness, pressure/temperature, and sealing requirements. We can recommend the suitable type based on your specific operating conditions.

Q: Can a parallel disc gate valve be used for throttling or flow regulation?

A: It is not recommended. Gate valves are designed primarily for full open or full close service. If kept partially open, high-velocity flow can cause erosion of the sealing faces, compromising sealing performance and valve lifespan. For flow regulation, we recommend using a dedicated control valve or globe valve.

Q: What media can small butterfly valves handle?

A: They work with air, water, oil, chemicals, and industrial gases, common in water treatment, oil, and chemical industries.
