Components used in piping

Introduction: Steam is perhaps one of the most efficient mode of energy transportation in the present times in Process Industry. However it has a potential of becoming highly inefficient if certain aspects associated with its handling are not appropriately addressed in the design of steam network. The aspects, which are of particular concern with respect to efficient and safe design ...

Introduction to Flush Bottom Valve Flush Bottom Valve  is a special purpose valve, which is used in piping, reactors and vessels to drain out abrasive, Slurry, Viscous Material or Semi Solid Media. This type of valve is available in the size from 15 MM to 150 MM with different material of construction like Cast Iron, Cast Steel, SS 304 / 316 ...

Introduction to Multi-port Valve Valves which perform duties other than the two way isolation, control and check are classified under the category of special purpose valves, few of such valves are Multi-port valves. Flush bottom valves Float valves Foot valves Multi-port Valves Multiport valve is categorized as a special purpose valve. The multi-port valve on certain services reduces the time for ...

Piston valve resembles in construction more towards a globe valve and is mainly used for shut off and regulation. This valve provides positive shut off. The shut off assembly comprises of a metal piston, two resilient valve rings and a metal lantern bush. The sealing surface consists of the outer vertical surface of the piston and the corresponding inner surfaces of ...

Needle Valve: The needle valve, like globe valve, is used for flow control. It allows precise regulation of flow, although it is generally only capable of relatively low flow rates. Normally needle valve is used in smaller sizes and is provided with either screwed or socket weld ends. The major body parts of needle valve are- Body Bonnet Packing Nut Stem Screw Handle ...

Double block and bleed valves are also known as DBB valves. This valve is a space-saving dual isolation solution that reduces the need for costly multi-valve systems. By combining all block and bleed components into a single unit, DBB valves minimize the risk of leak paths to atmosphere while providing significant weight savings. In many DBB valves, the isolation valve ...

Swing Check Valve: Swing check valve is a non-return valve which operates by the swinging action of the disk. This valve is used for sizes 2” and above. There are two types of swing check valves available. They are the conventional swing check valves with flanged ends and the wafer type spring loaded check valves. 1. Conventional Swing check valve: ...

Based on functions, valves are classified as isolation, regulation, non return valve and special type of valve.  Non Return Valve: As the name indicates, this non return valve is used to ensure unidirectional flow of fluids. It is used to prevent the back flow in order to safeguard the critical equipments such as pumps, compressor etc and also used for positive. ...

Butterfly valve: Butterfly valve is one of the types of valves positive shut-off quarter-turn valve. It’s majorly used in utility services such as air, gas, steam, or liquid because of two reasons: they are lower in cost and also they are light in weight. They are available in variety of design depending on the service and the pressure-temperature rating. These valves can ...
