What are different types of valves used for?
Valves are for starting or stopping flow, regulating or throttling flow, preventing back flow or relieving and regulating pressure in fluid or gaseous handling applications. Common valve types include: Ball,Butterfly,Check, Diaphragm, Gate, Globe, Knife Gate, Parallel Slide, Pinch, Piston, Plug, Sluice, etc.
Where is ball valve used?
Ball valve is the most used fluid shutoff valve in upstream oil and gas production facilities, both onshore and offshore. They are also used in fuel gas systems feeding furnaces. Plug valves present the following advantages: Resistance to high pressure.
Which valve is most commonly used in household applications?
Pressure balancing valves are the most common type of household valve. This type of valve has a single control and a handle.
Which valve is used for gas flow?
Ball Valves Ball valves are designed to control the flow of high pressure liquids and gases with minimal pressure drop. They are quick to open and close, and have a tight seal with low torque. Their ease of operation, repair, and versatility lends the ability to be used in a variety of locations.
What type of valve is used for steam?
Ball valves are commonly used in steam, water, oil, gas, air, corrosive fluids. They can handle slurries and dusty dry fluids. Ball valves are not used with abrasive and fibrous materials as it poses risk of damage to the seat and plug surface.
Which valve used in steam line?
Gate valve is mainly used for steam pipeline where no need frequent open or closure; The globe valve offers a better function of flow regulation.

What is linear valve?
Linear valves, also known as multi-turn valves, have a sliding-stem design that pushes a closure element into an open or closed position. These types of valves are extremely versatile with many different trim sizes and design options available. A globe valve would be an example of a control valve with linear motion.
What are the types of valve mechanism?
According to the location of the valves, the valve mechanism is of two types:
- Valve mechanism for operating the valve in engine block (straight poppet valve).
- Valve mechanism for operating the valve in the cylinder head (overhead poppet valve).
What are the different types of industrial valves?
The main types of industrial valves includes are ball, globe, gate, and butterfly valves among others Ball valves are used in rotational motion to start, stop or throttling the flow of fluids in the system. The industrial valves market can be further segmented by end use industries such as oil and gas, chemical and power among others.
What are the different valves used in plumbing?
A handle is used to control whether the valve is open or closed. Ball valves are made of several different materials, including bronze, steel, plastic, brass and iron. They are good for stopping the flow of water in the event of a plumbing emergency, such as a broken pipe.
What are the different types of pipe valves?
The many different types of valves all have different names. The most common ones are the butterfly, cock or plug, gate, globe, needle, poppet, and spool: Ball: In a ball valve, a hollowed-out sphere (the ball) sits tightly inside a pipe, completely blocking the fluid flow.
