( Brand: Parker ), ( Manufacturer Part Number: 2170020-101 ), ( Part Type: Valve Swing Check )
The Parker Aviation Swing Check Valve, model number 2170020-101, is a essential component in various aircraft hydraulic systems. This valve, also known as National Stock Number (NSN) 4820-00-507-2213, is designed to prevent the flow of hydraulic fluid in one direction while allowing it to flow in the opposite direction.
Precision engineered, this Parker valve is constructed from high-quality materials. The valve body is made from forged steel, ensuring strength and durability under the extreme conditions of aviation environments. The valve seat and disc are made from PTFE (Polytetrafluoroethylene), which is known for its exceptional chemical resistance and low friction properties.
This Parker Swing Check Valve features a simple yet effective design. The valve disc is hinged and swings open when pressure is applied in the desired direction, allowing fluid to flow. Once the pressure is relieved, the disc swings back to seal off the valve, preventing reverse flow. A stainless steel spring provides the necessary force for the disc to return to its sealing position.
The Parker 2170020-101 valve is available in different sizes and can handle a wide range of hydraulic fluid types and temperatures. It is suitable for use in aircraft systems that require reliable and efficient fluid flow control.
This valve is easy to install and maintain. It comes with a standard 1/8 NPT thread, making it compatible with a wide range of hydraulic connections. The valve also has an integrated strainer to help prevent debris from entering the valve and causing damage.
The Parker Aviation Swing Check Valve, model number 2170020-101, is a crucial component in aviation hydraulic systems. Its robust construction, effective design, and ease of installation and maintenance make it a reliable choice for maintaining the efficient and safe operation of aircraft systems.
The Parker Aviation Swing Check Valve (Model 2170020-101, National Stock Number (NSN) 4820-00-507-2213) is a critical component used in various aviation systems for preventing backflow. In this analysis, we will discuss the key features, advantages, and disadvantages of this valve.
Features:1. Swing check valve design: Allows for full flow in the forward direction while preventing flow reversal.
2. Made of durable materials: The valve body is typically made of brass, while the seats and discs are made of materials like PTFE or rubber for longevity.
3. Available in various sizes: The Parker Aviation Swing Check Valve is available in various sizes to cater to different applications.
Advantages:1. Reliable performance: Swing check valves offer reliable performance in high-pressure and high-velocity applications. They can effectively prevent backflow without causing turbulence or pressure drop.
2. Cost-effective: Compared to other valve designs, swing check valves are generally more cost-effective due to their simple design and easy manufacturing process.
3. Versatile: Swing check valves can be used in various applications, including fuel, hydraulic, and cooling systems.
Disadvantages:1. Limited sealing capability: Swing check valves may not be suitable for applications with large particles or high contamination levels, as they rely on a tight seal between the valve components.
2. Requires regular maintenance: The sealing surfaces of swing check valves may wear out over time, requiring regular maintenance and replacement of the seats or discs.
3. Not suitable for high-pressure drops: Swing check valves are not designed to handle large pressure drops. In such cases, other valve designs like ball or globe valves may be more appropriate.
Conclusion:The Parker Aviation Swing Check Valve (2170020-101, NSN 4820-00-507-2213) is a reliable and cost-effective solution for preventing backflow in various aviation applications. Its swing check valve design offers full flow in the forward direction while preventing reverse flow. However, it has some limitations, such as the need for regular maintenance and limited sealing capability for applications with high contamination levels. Ultimately, the decision to purchase this valve depends on the specific requirements of your application and the trade-offs between its advantages and disadvantages.
Recommendation:If you are looking for a reliable and cost-effective swing check valve for aviation applications, the Parker Aviation Swing Check Valve (2170020-101, NSN 4820-00-507-2213) is an excellent choice.
