Emechmart- Your trusted Plumbing partner
The plumbing valves are devices that allow, control, or direct the flow of fluid by opening, closing, or partially blocking it. A valve is a mechanical device that controls the flow and pressure of a fluid in a system or process. So basically, plumbing angle valve controls flow and pressure. Plumbing may be defined as the practice, materials, and fixtures for installing, erecting, piping, fixtures, equipment, and appliances in connection with sanitary or stormwater drainage facilities, venting systems, and public or private water supply systems. And Emechmart is your best plumbing partner to find the right types of plumbing valves.
Types of valves in plumbing available at Emechmart
Emechmart provides different variants of plumbing valves that are used in piping depending on the requirements in plumbing. The cost of plumbing valves in a piping system is between 20 and 30% of the total piping cost. And the value of a given type and size of plumbing valve can vary 100%.
That means if you choose a ball valve over a butterfly valve for the same function. It may cost you more. Therefore, the selection of plumbing isolation valve is essential for economics as well as the operation of the process plant.
1. Gate valve
It is a linear motion valve used to start or stop the flow of fluid. In service, these valves are either in the fully open or fully closed position. Gate valves are the most widely used valves in any process plant.
2. Globe valve
A globe valve plumbing is a linear motion plumbing valve used to stop, start, and control flow. A globe valve disc may be completely removed from the flow path or it may close the flow path completely. During the opening and closing of the valve, the disc moves perpendicular to the seat. Leakage from the globe valve seat is lower than that of the gate valve, mainly due to the right-angle contact between the disc and the seat ring, which allows for a tighter seal between the seat disc.
3. Check the valve
A plumbing water valve used to prevent backflow in a piping system is known as a check valve. It is also known as non-return valve or NRV. The pressure of the fluid passing through the pipeline opens the valve, while any reversal of flow will close the valve.
4. Plug valve
This type of valve is a quarter-turn rotary motion that uses a tapered or cylindrical plug to stop or start flow. The plug is disk-shaped, with a passage to pass the flow. The plumbing toilet valve is used as on-off stop valve and is capable of providing bubble-tight shutoff. Plug valves can be used for high pressure and temperature applications in vacuum.
5. Ball valve
A ball valve is a quarter-turn rotary motion valve that uses a ball-shaped disc to stop flow. It resembles a plug valve in many ways. When the ball port is in line, it allows flow. When you turn the valve 90 degrees, the solid part of the ball stops the flow. Most ball valves are of the quick-acting type, requiring a 90° turn of the valve handle to operate the valve. But for larger valves that require significant force to open or close the valve, gear-driven actuators are used. With this arrangement, a small handwheel is sufficient to operate a fairly large valve.
6. Butterfly valve
A butterfly valve is a quarter-turn rotary motion valve, used to stop, regulate and start flow. The body of the plastic plumbing valves is small and round. Butterfly valves are suitable for large valve applications due to their compact, lightweight design that requires significantly less space than other valves.
7. Needle valve
Needle valves are similar in design to globe valves with the major difference being a sharp needle-like disc. The copper valves plumbing are designed to provide very precise control of flow in small diameter piping systems. They get their name from their sharp-pointed conical discs and matching seats. A needle valve is a manual valve used for continuous throttling of flow for regulation. Needle valves are similar in design to globe valves with the biggest difference being the sharp needle-like disc.
