1/2" Miniature Electric UPVC Double Union 4-way Adjustable Ball Valve, DN15 Corrosion-Resistant Analog Adjustment Valve

Size and Material: The valve is a 1/2" (DN15) miniature valve. The use of UPVC (Unplasticized Polyvinyl Chloride) material provides excellent corrosion - resistance. UPVC is known for its ability to withstand a wide range of chemicals and harsh environments, making it suitable for various applications where corrosion is a concern.

Double Union Design: The double union feature allows for easy installation and removal of the valve from the piping system. This design simplifies maintenance and repair processes. For example, if the valve needs to be replaced or serviced, the unions can be quickly disconnected without having to cut or modify the entire piping system.

4 - way Adjustable Ball Valve: The 4 - way design means that the valve can control the flow of fluid in multiple directions. The ball valve mechanism provides a reliable shut - off and precise flow control. The ball inside the valve has a hole or port through which the fluid passes, and by rotating the ball, the flow path can be adjusted. The analog adjustment allows for fine - tuning of the flow rate, enabling users to set the desired flow according to their specific requirements.

Valve Body: The UPVC valve body houses the ball and other internal components. It is designed to provide a leak - proof enclosure for the fluid. The smooth interior surface of the body helps to reduce friction and pressure losses as the fluid passes through.

Ball and Seats: The ball is usually made of a durable material such as stainless steel or a high - quality plastic. The seats, which the ball seals against when in the closed position, are also designed to provide a tight seal. The sealing material is often a flexible elastomer that can conform to the shape of the ball and prevent leakage.

Handle and Adjustment Mechanism: The handle is attached to the ball through a shaft. When the handle is turned, it rotates the ball, changing the position of the flow port. The analog adjustment aspect means that the handle can be set to different positions between fully open and fully closed, allowing for a continuous range of flow rates. For example, a small rotation of the handle can result in a slight increase or decrease in the flow of fluid through the valve.

Laboratory Equipment: In scientific laboratories, this valve is used in fluid handling systems. It can control the flow of various chemicals, solvents, or reagents. For example, in a chromatography setup, the valve can be used to adjust the flow of the mobile phase through the columns precisely.

Small - scale Industrial Processes: In small - scale manufacturing or processing plants, it can be used to control the flow of raw materials or intermediate products. For instance, in a small - scale food or beverage processing plant, it can regulate the flow of ingredients such as syrups or flavorings.

Irrigation and Gardening: In small - scale irrigation systems, such as for potted plants or small gardens, the valve can be used to control the water flow. The 4 - way design can be useful for splitting the water flow into different directions for multiple plants or sections of a garden.

Corrosion - Resistance: As mentioned earlier, the UPVC material is highly resistant to corrosion. This makes it a long - lasting option, especially when dealing with corrosive fluids. It can reduce maintenance costs associated with valve replacement due to corrosion.

Versatility: The 4 - way design and analog adjustment make the valve very versatile. It can be used in a variety of applications where different flow patterns and rates are required. The ability to control the flow in multiple directions provides flexibility in system design.

Ease of Use and Maintenance: The double union design simplifies installation and maintenance. The analog adjustment with a handle is intuitive and easy to operate. If the valve needs to be cleaned or repaired, the double union allows for quick disassembly and reassembly.

Installation: When installing the valve, it's important to ensure that the piping is properly aligned with the valve ports. The double union connections should be tightened securely but not over - tightened to avoid damaging the valve or the piping. The valve should be installed in a position that allows for easy access to the handle for adjustment.

Maintenance: Regular maintenance includes checking the seals for signs of wear or leakage. The ball and the interior of the valve body can be cleaned periodically to remove any debris or buildup that could affect the valve's performance. If the handle becomes loose or difficult to turn, the adjustment mechanism may need to be tightened or lubricated.
