Valves ppt - SlideShare

Valves ppt 1. A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically fittings , but are usually discussed as a separate category.

Valve Types and Features - cgc.co.jp

Valve Types and Features The three basic functions of valves are: 1. to stop flow, 2. to keep a constant direction of flow, and 3. to regulate the flow rate and pressure. To select the correct valve to fulfill these functions properly, an outline of the different types of valves and their features is given below. Butterfly valve

Pinch valves consist of a stone tube/sleeve which is made up of reinforced elastomers. The sealing/ closing action is achieved by throttling or pinching this sleeve/tube. Pinch valves are best suited for handling slurries and fluids having suspended solids. Pinch valves offer many benefits over the other types of valves.

Choke valve, Butterfly valve used to limit air intake in internal combustion engine. Not to be confused with choke valves used in industrial flow control. Clapper valve: a type of check valve used in the Siamese fire appliance to allow only 1 hose to be connected instead of two (the clapper valve blocks the other side from leaking out).

Different Types of Control Valves | Instrumentation …

(a) Types of Control Valves based on Action: Control valves operated through pneumatic actuators can be either (i) air to open. (ii) air to close. They are designed such that if the air supply fails, the control valve will be either fully open, or fully closed, depending upon the safety requirement of the process.

Types of Valves - Assured Automation

Rotary Valves (also referred to as “quarter-turn” valves) These types of valves rely on the rotary motion of the flow obstructer In most cases this rotation is limited to 90 degrees (one quarter-turn), however, there are valves that operate using a larger degree of rotation and have more than 2 positions that are used in regular operation.

Valves Guide - Valves are mechanical devices that …

What are Valves? Valves are mechanical devices that controls the flow and pressure within a system or process. They are essential components of a piping system that conveys liquids, gases, vapors, slurries etc.. Different types of valves are available: gate, globe, plug, ball, butterfly, check, diaphragm, pinch, pressure relief, control valves etc.

What is a Check Valve? Learn about Check Valves …

The swing type valve allows full, unobstructed flow and automatically closes as pressure decreases. Usually installed in combination with gate valves because they provide relatively free flow combinations. A basic swing type valve consists of a valve body, a bonnet, and a disk that is connected to a hinge.


Each type of valve has been designed to meet specific needs. Some valves are capable of throttling flow, other valve types can only stop flow, others work well in corrosive systems, and others handle high pressure fluids. Each valve type has certain inherent advantages and disadvantages.
