Check valves are sometimes referred to as one-way valves, reflux valves, non-return valves, and retention valves. This kind of industrial valve, which falls under the automated valve category, is automatically opened and closed by the force created by the medium’s flow in the pipeline. In pipeline systems, check valves are employed to prevent backflow of the medium, reversing of the pump and its driving motor, and backflow of the medium from the container. The auxiliary system, where the pressure may exceed that of the main system, can also be refilled via the check valve.

Swing Check Valve

The Swing Check valve is to stop the medium in the pipeline from flowing back, so Axegic valve designed it. The valve fully closes to stop backflow as soon as pressure is zero.

Swing check valves are a type of automated valve that only allows one direction of flow, preventing mishaps in pipelines when the medium flows in one direction. In these sorts of valves, there are extremely little pressure dips and turbulence. The pipeline should typically have this sort of valve fixed horizontally, but it may also be mounted vertically as long as you bear in mind that the disc cannot reach the stalling position where it is trapped in the open position.

Dual Plate Check Valve

An example of a valve with two plates is a dual plate check valve, which is used to stop fluid flow in the opposite direction. When the pump is shut off or there is backflow, the piping system experiences reverse flow. Manufacturers of dual plate wafer check valves create this kind of valve for usage with a variety of media, including slurries, liquids, vapours, gases, and steam. Due to its flapping plates, dual plate wafer check valves can function well even in solid applications. In these situations, coated valve plates are used to increase abrasive wear. Additionally, these valves perform well in high-temperature and corrosive environments. This is due to the fact that manufacturers of dual plate wafer check valves employ materials in the design of these valves that can withstand corrosion in fluids like acids. A valve made entirely of metallic elements that can survive extreme heat and are inert at such high temperatures is intended specifically for usage at high temperatures.

Lift Check Valve

One kind of check valve used to stop fluid from flowing backward is a lift check valve. The fluid cannot flow backward since it would be blocked. Lift check valves are one-way valves, allowing just one direction of fluid flow. The usage of a lift type check valve is appropriate for high-pressure applications with high flow rates. Manufacturers of lift check valves build these valves such that the disc or ball is precisely guided by a close and long contact sliding fit with a centred dashpot. Manufacturers of lift check valves create these valves with globe valve-like T, straight through, or Y designs. Lift type check valves can be mounted either vertically or horizontally. However, in order for the gravity-dependent valves to function, lift check valve manufacturers advise installing them vertically.

Wafer Type Check Valve

Wafer type check valves are used in pipe systems to stop fluid from flowing in the other direction. Because they are smaller and thinner than conventional check valves, these valves are referred to as “wafers.” Wafer type check valves are automated, therefore a valve operator or actuator is not necessary. Because wafer type check valves are utilised in important applications like freshwater delivery, where even a little amount of contaminated fluid returning to the freshwater might result in health issues, these valves are built with a high level of dependability. Wafer type check valves are employed in a variety of pressure and temperature applications, from low to high.

Single Disc Wafer Check Valve

A check valve that has single disc and is used to stop reverse fluid flow is known as a single disc wafer check valve. Backflow or when the pump is switched off can cause reverse flow in the piping system. Slurries, liquids, vapours, gases, and steam are just a few of the numerous types of media for which single disc wafer check valves are used. Because of their flapping plates, single disc wafer check valves are able to function successfully even in solid applications. To improve abrasive wear, some applications employ coated valve plates. High-temperature and corrosive applications benefit from the performance of these valves.

This is due to the fact that manufacturers of single disc wafer check valves employ materials in the design of these valves that can withstand corrosion in fluids like acids. A valve made entirely of metallic elements that can survive extreme heat and are inert at such high temperatures is intended specifically for usage at high temperatures.

Single Flap Type Check Valve

A type of valve used to let fluid flow in one direction is a Single Flap Type Check Valve. Only fluid movement in the forward direction is permitted; anytime fluid tries to flow back, the valve closes. The pressure differential between the valve’s intake and exhaust ports determines whether the valve opens or closes. Manufacturers of Single Flap Type Check Valve create them without an actuator or handwheel since they function automatically by allowing fluid to flow forward and preventing it from flowing backward. Reverse fluid flow must be avoided to avoid fluid contamination in applications like those involving food and water. Additionally, this valve protects pumps and boilers from harm that may result from reverse fluid flow. Single Flap Type Check Valve can be utilised in corrosive and non-corrosive environments, as well as low and high temperatures. The material utilised to build the valve’s interior parts—the majority—determines the region of use.

Spring Loaded Check Valves

A type of valve called a spring loaded check valve is used to stop fluid flow in the opposite direction in many industrial applications. Alternatively referred to as a spring loaded non-return valve, a check valve has a spring that is loaded. The name of the valves refers to their ideal purpose, which is to ensure that fluid may only flow in one direction and cannot flow backward. These spring loaded check valves are manufactured by the companies that make actuators and valve operators so that they can operate automatically. Spring loaded check valves function as their name implies by employing a spring to open and close the valve.

These valves work by opening when there is a large pressure differential between the suction and outlet pressures, and closing when there is one. The spring uses the potential energy generated as fluid pushes through spring loaded check valves to assist in returning the closing portion of the valve to its sitting position. Manufacturers of spring loaded check valves make a variety of these valves for usage in various pressure and temperature ranges, as well as corrosive and non-corrosive goods.

Non Slam Check Valve

Non slam check valves, often referred to as nozzle check valves, are automated valve discs that open and shut based on the flow of the medium itself in order to reduce noise. An automated valve contains a non slam check valve. Its primary purposes are to release the medium from the container, stop the pump and drive motor from reversing, and prevent medium backflow. The supply lines that refill the auxiliary system can also employ the non-slam check valve if the pressure there rises above the system pressure.

The non slam check valve’s function is to stop flow in the opposing direction and permit just one way for the media to flow. This valve typically operates automatically. When a fluid is flowing in one direction, the valve disc opens; when a fluid is flowing in the other direction, the valve disc acts on the valve seat to stop the flow as a result of the fluid pressure and the valve disc’s self-coincidence. It is not appropriate for mediums with high viscosities and solid particles.

Stainless Steel Check Valve

A stainless steel check valve is a type of valve designed to stop the flow of fluid in the opposite direction. When the pump is switched off or the suction pressure drops, fluid flows in the opposite direction. Reverse-flowing fluid in a pipe system may be extremely hazardous since it might cause fluid contamination or piping system damage. Steel that is exceptionally robust and has a high melting temperature is used in the creation of stainless steel check valves. Additionally corrosion-resistant is this substance. Stainless steel check valves can function in corrosive, high pressure, and high temperature environments as a result of these characteristics. These valves are made by producers of stainless steel check valves without a valve actuator, hand wheel, or lever. By using the pressure differential between the intake and exit sides, these valves function independently. Check valves made of stainless steel come in a variety of varieties and are utilised in several applications.
