This type of valve is indicated by "O. S. and Y." is a common design for NPS 2 and larger valves. Rising Stem with Inside Screw The threaded part of the stem is inside the valve body, and the stem packing along the smooth section that is exposed to the atmosphere outside. In this case, the stem threads are in contact with the flow medium.

Types of gate valve based on body, bonnet connection. 1st is screwed bonnet: This is the simplest design available and it is used for inexpensive valves. 2nd is bolted-bonnet: This is the most popular design and used in a large number of gate valves. This requires a gasket to seal the joint between the body and bonnet.

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

fittings like elbow, union, gasket, etc., joints and valves, and where these should be used while carrying out the tasks. Not only does this help in smooth functioning, but also ensures cost-effectiveness. For proper installation of the plumbing system in a building, various types of joints are used, which are shown in Fig. 5.1. As already

Types of Check Valves: Ball Check Valves Unlike other valves, ball check valves use a spherical ball inside their bodies to help control the flow direction in pipes and systems. This ball rotates freely when fluid passes through the system, which causes a wiping motion and even wear between the ball and seat.

Control Valves are mechanical devices that can regulate or control the flow or pressure of the fluid by fully or partially opening the fluid passageways.. Various types of valves are used in the piping system to control the flow. For example, the water tap is a type of valve …

The electric expansion valve (EEV) provides a means by which applications can be designed with sophisticated system control functions. This type of valve is controlled by an electronic circuit which is often designed to allow the valve to control some aspect of system operation in addition to superheat at the outlet of the evaporator. For

Dec 13, 2016· Types of valves. 1. TYPES OF VALVES. 2. Globe Valves A globe valve is a linear motion valve used to stop, start, and regulate fluid flow. The three primary body designs for globe valves are Z-body, Y-body, and Angle. Advantages o Recommended for throttling applications. o Good for frequent operation. o Easy to repair.

Chapter 3 covers valve and actuator types. Chapter 4 describes digital valve controllers, analog positioners, boosters, and other control valve accessories. Chapter 5 is a comprehensive guide to selecting the best control valve for an application. Chapter 6 covers the selection and use of special control valves.

Valve Types • Vertical Valve – Vertical pressure on the actuator opens the valve • Tilt Valve – Forward pressure on the actuator opens the valve. Lindal North America 54 Valve Types • Up/Down Valve – Uses a special housing for upright or inverted use – Not a true 360 degree valve.

The control valve symbols on a P&ID differ depending on the type of valve specified for the application. Each P&ID has its own legend that identifies the symbols for the various equipment. While there is some variation, examples of the standard symbols for control valves are in the PDF below. Symbols include: gate valve symbol. globe valve symbol.

A valve is a component that controls and regulates the fluid or directs the flow of a fluid by various kinds of closing, opening, or by partially cut off fluid flow. So to controls the flow and pressure of fluid within a system, we used valves. Now our main topic valve types, Valve types:
