BALL VALVES
If you have basic valve knowledge, you are probably familiar with ball valve – one of the most common types of valves available today. A ball valve is typically a quarter-turn valve with a perforated ball in the middle to control flow. These valves are known for being durable with excellent shut...Read more -
BUTTERFLY VALVES
The butterfly valve comprises a ring-shaped body in which a ring-shaped elastomer seat/liner is inserted. A washer guided through a shaft swings through a 90° rotary movement into the gasket. Depending on the version and nominal size, this enables operating pressures of up to 25 bar and temperat...Read more -
DIAPHRAGM VALVE
Diaphragm valves get their name from a flexible disc which comes into contact with a seat at the top of the valve body to form a seal. A diaphragm is a flexible, pressure responsive element that transmits force to open, close or control a valve. Diaphragm valves are related to pinch valves, but u...Read more -
FLANGES
WELD NECK FLANGE Weld neck pipe flanges attach to the pipe by welding the pipe to the neck of the pipe flange. The allows for the transfer of stress from the weld neck pipe flanges to the pipe itself. This also reduces high stress concentration at the base of the hub of the weld neck pipe flan...Read more -
WHAT YOU NEED TO KNOW ABOUT THE FORGED FITTINGS
Forged steel fittings are pipe fittings that are made from forged carbon steel material. Forging steel is a process that creates very strong fittings. Carbon steel is heated to molten temperatures and placed in the dies. The heated steel is then machined into the FORGED FITTINGS . High-strength...Read more -
CARBON STEEL BUTTWELD STD ASTM A234 WPB ANSI B16.9 180 DEG BEND
The advantages of Buttweld include Welding a fitting to the pipe means it is permanently leak proof. The continuous metal structure formed between pipe and fitting adds strength to the system Smoother inner surface and gradual direction changes reduce the pressure losses and turbulence and minim...Read more -
PIPE FLANGES
Pipe flanges form a rim that radially protrudes from the end of a pipe. They have several holes that allow two pipe flanges to be bolted together, forming a connection between two pipes. A gasket may be fitted between two flanges to improve the seal. Pipe flanges are available as discrete parts f...Read more -
WHAT IS WELDOLET
Weldolet is the most common among all pipe olet. It is ideal for high pressure weight application, and is welded onto the outlet of the run pipe. The end are bevelled to facilitate this process, and therefore the weldolet is consider a butt weld fitting. Weldolet is a branch butt weld connection ...Read more -
WHAT IS A TUBE SHEET?
A TUBE SHEET is usually made from a round flat piece of plate,sheet with holes drilled to accept the tubes or pipes in a accurate location and pattern relative to one another.The tube sheets are used to support and isolate tubes in heat exchangers and boilers or to support filter elements.Tubes ...Read more -
ADVANTAGES AND DISADVANTAGES OF THE BALL VALVES
Ball valves are less expensive compared to other types of valves! Plus, they need less maintenance as well as low maintenance costs. Another advantage of the ball valves is that they are compact and provide tight sealing with low torque. Not to mention their quick quarter turn on / off operation....Read more -
BALL VALVE WORKING PRINCIPLE
To understand the working principle of a ball valve, it is important to know the 5 main ball valve parts and 2 different operation types. The 5 main components can be seen in the ball valve diagram in Figure 2. The valve stem (1) is connected to the ball (4) and is either manually operated or aut...Read more -
INTRODUCTION TO VALVES TYPE
COMMON VALVE TYPES AND THEIR APPLICATIONS Valves feature a range of characteristics, standards, and groupings the help to give you an idea of their intended applications and expected performance. Valve designs are one of the most basic ways to sort the huge range of valves available and finding a...Read more
