UAE valves is one of the most intrusted Check Valve Supplier in Dubai, which offers a range of premium check valves suitable for different industries. They are made strong and reliable with effective protection in important systems, including chemical processing, oil and gas pipelines, and water treatment functions.
A check valve is one of the required components of liquid and gas systems, which only allows fluid flow in one direction. It acts as a safety valve to prevent reverse streams that can destroy the tool, pollute the system, or prevent any process. The check valve works automatically by

using the pressure difference on the inlet and outlet and stops in opening or closing without manipulation. The primary purpose of this control is to ensure that a pipeline or system has a uniform flow so that pumps, compressors, and all sensitive equipment are protected from backwards.
Types of Check Valves:
1. Dual Plate Check Valve The valve has two hinged plates that open and close as the flow pressure dictates to it. It is compact, lightweight, and typically associated with systems that require less space. Because of the dual nature, a swift seal reduces the possibility of backflow. Although relatively difficult to check, they are used in water treatment, HVAC systems, and high-flow applications.
2. Forged Steel Check Valve: These valves provide strength and durability. They are designed for heavy-duty applications in high-pressure systems, such as those that occur in oil and gas, petrochemicals, and power generation.
3. A single-plate check valve is quite different from the others, as it does not rely on dual plates to facilitate the direction of flow; instead, it makes use of a single disc. It has a high preference for lower volume applications and systems whereby simplicity is an essential requirement; it usually applies in household, business, and lesser industrial set-ups.
4. Swing Check Valve: This valve contains a disc, which opens by the presence of flow and closes if there is no flow or the flow reverses. Swing check valves are widely used in large pipelines where the flow rates are greater, and preventing backflow is highly essential. They are found to be very effective for protecting pumps and other equipment from back flow damage.
5. Lift Check Valve This valve consists of a disc that lifts from its seat on flow in one direction and rests on it when the flow direction gets reversed. This type of valve is generally used for vertical piping or pipelines of relatively lower flow velocity. They provide a good option to protect sensitive appliances.
6. Pressure Seal Check Valve: Designed for high-pressure applications, these valves use a pressure-seal mechanism that strengthens as the pressure increases. This ensures a tight seal even under extreme conditions, making them ideal for use in steam, gas, and high-pressure water systems.
7. Tilting Disc Check Valve: In this design, the disc tilts in one direction to allow the flow and seals in another direction to prevent backflow. This design causes less turbulence in the flow. It is used in very large industrial and municipal systems handling high-flow liquids and gases.
Swing Check Valve Use
Swing check valves are particularly useful in systems where large amounts of liquid or gas flow through pipelines, such as in water, sewage, and industrial applications. It protects pumps and compressors in case of reverse flow that may damage them. Swing check valves are also particularly useful in systems of a high probability of reverse pressure and intermittent flow. Their design makes them especially suited for larger pipelines where efficient and reliable operation is crucial.
What is cracking pressure on a check valve?
Cracking pressure is the minimum pressure that a check valve requires for it to open. It is the pressure at which the valve starts to allow fluid flow in the needed direction. In order to perform best, especially in low pressure or pressure flow systems, crack pressure must be adjusted sometimes. For example, in a high pressure system, a high crack pressure will be necessary to avoid unwanted backflow. Lower cracking pressure may avoid excessive strain on the system.
Applications Where Check Valves Are Used
Check valves are used in a myriad of applications throughout a range of industries, including but not limited to:
Oil and Gas: protecting pipelines and pumps from backflow to allow for safe and efficient operations
Water Treatment: preventing backflow and contamination within municipal and industrial water systems
Chemical Processing: prevention of backflow of hazardous chemicals into equipment or storage tanks.
- Turbines and Pumps: Prevent the turbines and pumps from being damaged on account of backflow
- Heating, Ventilation, and Air-Conditioning Systems : Adequate direction of the fluid in the heating, ventilation, and air-conditioning systems
