The Belimo B-338 1-1/2" B3 3-way Characterized Control Valve with a steel ball stem is a high-performance solution for HVAC and process automation applications. This valve is designed to ensure precise flow control and optimal energy efficiency.

The B-338 valve features a 3-way, characterized design, which allows for air or liquid flow in three directions: normally open (NO), normally closed (NC), and positioner controlled (PC). The PRV (Pressure Relief Valve) is factory-installed to ensure safe and reliable operation. The valve also comes with an integrated positioner and solenoid coil, as well as EEXd and UL/CSA certifications.

One of the standout features of the B-338 valve is its steel ball stem, which is highly resistant to wear and offers excellent durability. The stem design also ensures minimal stem wear and eliminates the need for stem packing. The valve body is made of forged body cast PA-8, which is known for its high strength and resistance to corrosion.

The B-338 valve offers superior flow characteristics with its sophisticated design, ensuring accurate and consistent flow control. The valve's characteristic curve can be easily adjusted to meet specific process requirements using Belimo's proprietary EASYBUS compatibility. This allows for seamless integration with various building and process automation systems.

The valve is available in various materials and sizes to cater to different applications, including Type 2 and Type 3 materials for highest corrosion resistance. The valve is also designed to meet ISO 5207-1 (Air Conditioning and Heating Equipment and Ventilation Systems Controls) standards, ensuring compatibility with various control systems.

The B-338 valve is equipped with a pneumatically actuated diaphragm control unit, which responds quickly and precisely to signal input. The control unit also comes with a built-in solenoid coil, which provides auxiliary functions such as blowing or vacuuming for applications like air comedy or filters.

Maintaining the B-338 valve is simple and easy. The valve features a top entry ball design, which minimizes maintenance time by allowing easy access to the internals during operation. The interchangeable parts and fast exchange design also make replacement quick and efficient in case of wear or failure.

Overall, the Belimo B-338 1-1/2" B3 3-way Characterized Control Valve with a steel ball stem is a reliable, durable, and efficient solution for various HVAC and process automation applications.

Details:

Suitable return actuators for the b338 type CCTV valve include: ar series non-spring. The flow the CV value is reduced to the required value by a combination of hole in ball and shaped aperture disc. This produces better part-load behavior and improved stability of control while also optimizing energy consumption. A special characterizing disc inside the valve gives it an equal percentage characteristic which is comparable with that of a globe same nominal size.

This valve is suitable for use in a hydroponic system with variable or constant flow. This type of characteristic produces a linear variation in thermal output according to the amount opening valve also known as system. In order to ensure good stability of control, it is essential for a control valve have an equal percentage characteristic. Product highlight: flow capacity CV 19 CV.

This valve is typically used in air handling units on heating or cooling coils, and fan coil unit coils. The increase in flow as the valve is opened very slow and controlled. 1-1/2 b3 series, 3-way characterized control brass valve w/ stainless steel ball stem 19.0 CV. Stainless steel ball stem, forged brass body.

Some other common applications include unit ventilators, vac box re-heat coils and bypass loops. When it is installed in a real system, however, this characteristic seriously deformed because, compared with its nominal size, ball valve possesses an extremely high flow coefficient. Female threaded connection. Under normal testing conditions a conventional ball valve exhibits an s-shaped characteristic.

Product highlight: size 1-1/2. Product highlight: connection type. Belimo unique characterized control valve CCTV is very different. AF series spring.
