SVR Global is a prominent Check Valve Manufacturer in USA. We have a broad product line of industrial valves to meet customer requirements. Our products in this diverse market provide another example of our customer-driven, problem-solving capabilities. Definition of a Check Valve: A Check valve is a self-actuated, straight-line valve. An interesting feature of this valve is the possibility to set the valve opening with a specific pressure value, to ensure that the fluid reaches users, with a certain pressure value. A Check valve is a mechanical device that allows only unidirectional fluid flow. It is also called 'One-way valve', 'Clack valve' or 'Non-return valve' since it only allows media to flow in one direction. It has two media ports, one inlet and one output. Usually, a check valve is formed by a shutter, a spring and a gasket. How does a Check Valve work? The operating principle is very simple: as soon as the fluid pumped into the pipe reaches a pressure value that overcomes the force of the spring, the shutter will open and it will let the fluid flow through. The higher the fluid pressure, the bigger the shutter opening will be. When the pressure value falls below the value that counteracts the force of the spring, the shutter closes, preventing any backflow. Applications of a Check Valve: Virtually every plumbing or fluid transfer application imaginable, be it industrial, commercial, or domestic, employs check valves. Check valves are often utilized for one of four reasons in a number of applications because of how they work: ● To prevent backflow damage to downstream equipment ● To avoid contamination as a result of reverse flow ● To avoid siphoning ● To maintain a vacuum seal Advantages of a Check Valve: ● Backflow prevention ● Capability to withstanding both high and low pressures ● Can be utilized horizontally and vertically ● Used as a backup and safety system ● Self-actuated ● Fast-acting ● Reduce downtime and production losses. ● Avoid water hammer. ● Reduce unexpected valve failure. ● Maintenance expenditures are reduced. ● Adaptable to changing flow conditions ● Operating without the use of electricity ● Minimal pressure drop Disadvantages of a Check Valve: ● Non-operational in pulsating system ● The closing part may bang, resulting in seat damage and wear. ● Work in a completely confined environment. ● Impossible to tell whether they are open or closed. ● Internal components cannot be examined. ● Occasionally, discs become caught in the open position. ● Slamming discs are noisy ● Hammering with water ● Problems with reverse flow ● Tapping & Chattering ● Disc banging in the open position, resulting in damage and wear. ● Cannot be operated with fluid containing solid particles as they may accumulate between the seat and disc and stop the disc from closing. Industries that use Check Valves: Check valves are used in Sewage Water treatment Chemical processing Power generation Hydropower Petrochemical Oil and gas Gas plants LNG Liquid gases Refineries Petrochemical Chemical Fertilizer Power Desalination Types of Check Valves- Dual Plate Check Valve Also known as Silent Check Valve, a Dual Plate Check Valve is an automatic mechanical non-return valve, which opens with a forward flow and shut to a reversal inflow. It consists of 2 discs attached to the valve body by a pin and operated by the action of springs, which immediately start closing the valve when the fluid stops. Forged Steel Check Valve Forging steel check valves are compact, sturdy, and ideal for high-pressure and high-temperature applications. These are non-return valves that only operate in one direction. The body is built of forged steel and is available in two-port configurations: full and standard. A forged steel lid sits atop the body. Swing Check Valve Swing check valves use a swinging disc on a hinge to regulate the flow of a liquid, gas, or solid stream in one direction while preventing backflow from contaminating the source fluid. In other words, like all check valves, the swing valve is a non-return valve. Swing check valves are the most common type of large check valve, and a typical example is a toilet flushing valve that rises and lowers. Swing valves normally require some type of physical motion to activate them, therefore manual twisting of the handle is a common subject. In some internal pipe systems, however, a spring check valve is integrated with the swing valve to eliminate the need for human intervention.

To satisfy customer needs, we offer a wide range of industrial valves. Our products focus on the needs of the client and problem-solving skills. Definition of a Forged Steel Check Valve: Check valves made of forging steel are compact, reliable, and perfect for high-temperature and high-pressure applications. These valves have a single-direction operation and are non-return valves. The body is made of forged steel and comes in two-port configurations- Full and Standard. On top of the body is a forged steel lid. Features of a Forged Steel Check Valve: • Enhanced durability • Easy installation • Resistance against corrosion Advantages of a Forged Steel Check Valve: • Allows a full and unobstructed flow • Low cost • Maintains pressure • Prevents backflow • Used both horizontally and vertically Industries that use Forged Steel Check Valve: • General Industry • Petrochemical • Power Plant • Process Industry • Refinery • Steel Plant • Sugar Industry What is Forging? Forging is a manufacturing process involving the shaping of metal through hammering, pressing, or rolling. These compressive forces are delivered with a hammer or die. Forging is often categorized according to the temperature at which it is performed- cold, warm or hot forging. A wide range of metals can be forged. What is Forged Steel? Forged steel is created by alloying iron and carbon under great pressure. Forged steel has lower surface porosity, a finer grain structure, stronger tensile and fatigue strength, and more ductility than other treated steels. When steel is heated to forging temperature, it becomes ductile and malleable, allowing it to be molded into the required shape with force and pressure. Using our processing methods and steel forging, we can shape a permanent steel item without it cracking. What is a Check Valve? Check valves are classed as self-actuated, straight-line valves.
