Apollo 77C-206-04 BRZ Ball Valve (Lot of 2)

The Apollo 77C-206-04 BRZ Ball Valve is a type of ball valve manufactured by Apollo Valves. This particular model is designed for industrial applications and features a bronze (BRZ) construction, making it suitable for various fluid and gas control systems. Below are the key details and features of this specific valve model:

Key Features:

1. Material – Bronze (BRZ):

   • The “BRZ” designation in the model number indicates that the ball valve is constructed from bronze.
   • Bronze is commonly used in applications where resistance to corrosion is important, particularly in systems with water, steam, and non-corrosive chemicals. It is an alloy primarily composed of copper and tin, which makes it more resistant to corrosion compared to materials like steel.
   • Bronze is ideal for systems where a combination of good strength and corrosion resistance is needed, such as in water treatment, HVAC systems, and marine applications.

2. Ball Valve Design:

   • This valve is a ball valve, which features a spherical ball with a hole through the center that controls the flow of fluids. The valve operates with a quarter-turn mechanism, meaning the valve is either fully open or fully closed with a 90-degree rotation of the handle or actuator.
   • Ball valves are often used for their ability to provide a reliable, tight shutoff and quick operation.

3. Size and Connection Type:

   • The model number 77C-206-04 typically refers to specific size and connection configurations. The “04” may indicate the size of the valve, typically corresponding to 1/4” or 1/2” NPT (National Pipe Thread) threaded connections, though the exact size should be verified by consulting product documentation.
   • Threaded NPT connections are common in smaller-sized ball valves and allow for easy installation in pipe systems without the need for welding.

4. Pressure Rating:

   • While the exact pressure rating should be verified in the datasheet for this specific model, bronze ball valves generally have pressure ratings that range from 150 PSI to 300 PSI, depending on the size and design. For higher pressure systems, valves made from materials like steel or stainless steel are typically used, but for medium-pressure applications, a bronze ball valve is a reliable choice.

5. Temperature Range:

   • Bronze valves generally have a moderate temperature range, often between -20°F and 400°F (-28°C to 204°C), although this depends on the exact design and sealing materials used.
   • For extremely high or low temperatures, it is important to check the specific temperature rating from the manufacturer’s datasheet.

6. Application:

   • The Apollo 77C-206-04 ball valve is typically used for applications requiring flow control in low-to-medium pressure systems, especially where corrosion resistance is crucial.
   • Typical applications include water systems, steam lines, air systems, and chemical processes where moderate flow control and durability are needed.

7. Body and Seal:

   • The body of the valve is made from bronze, while the seals inside the valve are typically made from materials such as PTFE (Teflon), Viton, or other durable sealing compounds designed to withstand various chemicals and temperatures.
   • Proper sealing is important for ensuring the valve remains leak-proof, especially when used in systems where fluids may be under pressure.

Benefits:

• Corrosion Resistance: Bronze is more resistant to corrosion than many other metals, making it ideal for use in wet or corrosive environments (e.g., water treatment plants or HVAC systems).
• Ease of Operation: Like most ball valves, the 77C-206-04 is easy to operate with a quick quarter-turn mechanism, allowing for rapid shut-off or flow regulation.
• Compact and Reliable: Ball valves like the 77C-206-04 are generally compact in size and can provide long-lasting, reliable service with minimal maintenance.

Typical Applications:

• Water Treatment Systems: Controlling the flow of water and other liquids in pipes.
• Steam Systems: In applications like HVAC systems or boilers where steam needs to be regulated or isolated.
• General Fluid and Gas Control: In industrial environments where a durable, reliable valve is needed for controlling fluids or gases at moderate pressures.
• Marine Systems: Bronze’s resistance to corrosion makes it a preferred material in marine or coastal applications.

Maintenance:

• Inspection: Regular inspection is recommended to ensure the valve continues to operate smoothly and maintain its sealing integrity.
• Cleaning: In applications with heavy particulates, cleaning the valve periodically to remove buildup can help maintain performance.
• Lubrication: Some valves may require occasional lubrication of the stem or seals to keep the valve working smoothly.
