Introduction to Angle Globe Valve
Introduction to Angle Globe Valve
2024-03-06

Angle globe valve is a common pipeline valve designed with a special angle structure to provide more flexible and effective fluid control. 1. Structural features: The main feature of an angle globe valve is that its valve body is designed in an angular shape, usually 90 degrees or other specific angles. This is different from traditional through type globe valves. The angled structure makes the valve move more smoothly when closing and opening, while reducing the resistance of fluid passing through. 2. Working principle: The working principle of the angle globe valve is basically similar to that of a general globe valve. The valve opens and closes the valve disc by rotating, thereby regulating the fluid flow in the pipeline. The valve structure with angular design helps to reduce the resistance of fluid flow and improve flow efficiency. 3. Scope of application: Angle globe valves are widely used in pipeline systems in various fields, including industry, chemical industry, HVAC, water supply and drainage systems, etc. Its design features make it more suitable for situations that require high fluid flow efficiency or are installed at an angle. 4. Operation mode: The angle globe valve can be operated manually, electrically, or pneumatically. Manual operation is suitable for some small systems, while electric and pneumatic operation are more suitable for large systems, improving the convenience and automation of operation. 5. Advantages: High flow efficiency: Angular design helps to reduce the resistance of fluid flow and improve the flow efficiency of pipeline systems. Smooth operation: The angle structure of the valve makes the opening and closing movements smoother, reducing operational resistance. Strong adaptability: suitable for various pipeline systems, especially in some working conditions with strict requirements for fluid flow efficiency, it performs better. 6. Application scenario: Angle globe valves are commonly used in situations that require frequent fluid regulation, such as industrial and chemical production processes that require regular fluid shut-off or regulation in pipeline systems. In summary, angle globe valves play an important role in pipeline control due to their unique angle design, providing an efficient and flexible solution for fluid control.

Introduction to Bellows Globe Valves
Introduction to Bellows Globe Valves
2024-03-01

The bellows globe valve is a commonly used valve in pipeline systems, designed with a bellows structure that imparts greater flexibility to the valve. 1. Structural Features: The main characteristic of the bellows globe valve lies in its use of bellows as the sealing element. Bellows is a flexible metal tube formed by multiple layers of corrugations, offering high bending and flexing capabilities. This structural design allows the bellows globe valve to better accommodate the bending and expansion of pipelines during operation, thereby enhancing the valve's reliability and durability. 2. Sealing Performance: The bellows portion of the bellows globe valve serves as the sealing element, providing excellent sealing performance. Due to the flexible deformation capability of the bellows, it can better conform to the valve seat when the valve is closed, ensuring a tight seal and effectively preventing media leakage. 3. Application Range: This type of valve is suitable for general industrial pipelines, HVAC (Heating, Ventilation, and Air Conditioning) systems, water supply and drainage systems, and other fields. Due to the special structure of its bellows, the bellows globe valve is particularly well-suited for situations where consideration of pipeline bending and expansion is necessary. 4. Operation Method: Bellows globe valves are typically operated manually, electrically, or pneumatically. Manual operation is suitable for small-scale systems, while electric and pneumatic operation are more applicable to large-scale systems, enhancing convenience and automation in operation. 5. Advantages of Use: The bellows globe valve offers superior adaptability and sealing performance compared to traditional globe valves. Additionally, its simple structure and easy maintenance contribute to reduced operational costs. In general, the bellows globe valve, with its distinctive bellows structure, is widely employed in pipeline systems, offering a more reliable and efficient valve solution for industrial and construction sectors.

Introduction to Double Jacket Gate Valve
Introduction to Double Jacket Gate Valve
2024-01-29

The double jacket gate valve is a specially designed valve with a dual-layer jacket structure, consisting of an inner and an outer jacket. This design is primarily aimed at providing precise temperature control of the internal fluid within the valve, making it suitable for operations in extreme temperature environments. The following is an introduction to the double jacket gate valve. Structure Inner jacket: mainly used to control the inner layer of fluid flow. Outer Jacket: The outer jacket is a layer located outside the inner jacket, and its main function is to provide additional insulation or cooling. Through the outer jacket, a thermal carrier or cooling medium can be introduced to influence the temperature of the environment surrounding the valve. Application scenarios 1. High-Temperature Applications: Double jacket gate valves are suitable for situations that require operation in high-temperature environments. The outer jacket can maintain the temperature around the valve by introducing a cooling medium, ensuring that the fluid inside the inner jacket operates at an appropriate temperature. 2. Low-Temperature Applications: They can also be used in low-temperature environments by introducing a thermal carrier into the outer jacket to provide insulation, preventing the freezing of the valve structure. Temperature control The double jacket structure allows the adjustment of the temperature in the vicinity of the valve by introducing heating or cooling media into the outer jacket, ensuring that the fluid inside the inner jacket operates within an appropriate temperature range. Industry applications In industrial sectors such as chemical, petroleum, and natural gas industries, the double jacket gate valve is widely employed, particularly in complex processes that require temperature control of fluids. In certain laboratory or production environments where precise control of fluids is necessary, double jacket gate valves may also be utilized. Anti-freeze insulation In cold environments, the design of the outer jacket can also be utilized to prevent the freezing of the valve structure, ensuring the normal operation of the valve. Overall, the double jacket gate valve, through its unique structural design, provides a stable working environment for fluids under different temperature conditions. It is suitable for industrial and experimental scenarios where higher temperature control requirements are needed.

General Description

Dual Plate Wafer Check Valves have been the preferred choice for decades due to their proven reliability and low pressure drops.


Features

-Low Pressure Drop

Dual plate wafer check valves have larger open area than other designs, thus reducing pressure drop compared to swing, lift or other check valves.


-Light Weight

Reduces weight by 80–90% compared to conventional Flanged check valves.


-Lower Cost

Light weight, compact profiles and the elimination of flanges allows Dual plate Wafer check valves to be manufactured more economically than other designs, especially as pipe diameters increase.


-Alleviates Water Hammer

Our spring activated discs are designed to close our valves quickly. This assures high performance, eliminating chatter and creating dynamic responsiveness in a non-slam design.


-Simple Installation

Easier to install, remove and replace in both new and existing piping systems.
