Detailed Description

Check Valve a popular type of pipe valve are used to prevent flow reversal in piping systems. Check valves are appropriate for service in horizontal or vertical piping tuns. In other words, check valve is a mechanical device that allows fluid to flow through it in only one direction. Check valves consist of two-port valves. This means that they have two openings in the body, one for fluid to enter and the other for fluid to leave. That is why they are classified as “one-directional valves”. They are available in various designs, sizes and materials and used in a wide variety of applications. Materials used: Brass Copper Cast Iron Bronze Ductile iron Stainless steel Metal alloys Plastic Ceramic etc. Following the complete list of Check Valves: + Cast Steel Swing Check Valve + Butterfly Swing Check Valve + Cast Steel Pressure seal Swing Check Valve + DIN Swing Check Valve + Flanged End Check Valve 150Lb~600Lb + Forged Steel Pressure seal Swing Check Valve + Piston Check Valve + Y-Pattern Piston Check Valve Uses of check valve: Check valves are best suited for moderate velocity applications. They are often part of common household items. They work automatically. They do not have any valve handle or stem. They are self-activating safety valves. They permit gases and liquids to flow in only one direction. They prevent liquid flow from reversing. They are used in many fluid systems like in chemical and power plants, and in many other industrial processes. They are capable of mixing multiple gases into one gas stream. Check valves are installed in irrigation sprinklers and drip irrigation emitters to keep the lines from draining when the system is shut off. Working of a check valve: There is a hinged ball or door which is placed inside the valve. With the pressure coming upstream the ball is held open. On the other hand, when the pressure increases on the downstream side, it forces the ball or door to close which stops any back flow. An important factor in check valves is the cracking pressure. This is the minimum upstream pressure at which the valve will operate. Typically the check valve is designed in such a way to specify a specific cracking pressure. Type of Valves: A valve is a piping components complete with operating system, able to control or shut off a fluid flow Valves are divided in: Ball Valve, Butterfly Valve, Check Valve, Gate valve, Globe Valve, Plug Valve, Power Station Valves, Y-Type Strainer, New Products Tel: +86-21-3378-0199 Fax:+86-21-5107-9722 E-mail: pfasia8@gmail.com Http://www.pipefitting.asia
