The Parker Hannifin HDF120A Hiross Mechanical Float Drain is a high-performing and reliable solution for your liquid retention applications. This drain features a unique Hiross design, where the float ball is simultaneously used as a check ball, ensuring automatic and continuous draining while preventing backflow. This design provides efficient and trouble-free operation, making it an ideal choice for applications where continuous manual draining is not desirable.
The HDF120A is constructed from durable materials, including a brass body with a polished chrome plating for resistance to corrosion and wear. The float ball and internal components are made from high-density polyethylene (HDPE), which is lightweight yet strong, and resistant to chemical attack and impact. This drain is suitable for applications with liquids containing water, oil, or other non-corrosive substances, making it a versatile option for various industries.
The drain operates by using the buoyancy of the float ball to open the drain valve when the liquid level reaches the desired point. As the fluid level drops, the float ball returns to its original position, automatically sealing the valve to prevent any backflow. This mechanism ensures a consistent and reliable operation, providing efficient removal of the liquid without the need for constant monitoring or manual intervention.
The installation process for the HDF120A is simple and straightforward. It is suitable for installation in vessels, sumps, or other containers with a maximum working pressure of 15 psi (1.07 bar) and a maximum temperature of 257 F (125 C). It can be installed in both horizontal and vertical orientations, making it a versatile option for a wide range of applications. For installation, a 3/4-inch NPT thread is provided on the drain body, while a 1/2-inch NPT thread is provided on the float ball.
In conclusion, the Parker Hannifin HDF120A Hiross Mechanical Float Drain is an exceptional choice for applications requiring reliable and continuous liquid draining. Its unique Hiross design, durability, ease of installation, and versatility make it an excellent addition to various industries and applications, ensuring efficient and trouble-free operation.
The Parker HDF120A Hiross Mechanical Float Drain is a popular choice for various industrial and agricultural applications. Let's explore the advantages and disadvantages of using this drain valve:
Pros:1. Durable Construction: The Parker HDF120A is known for its heavy-duty design. It is made with high-quality, corrosion-resistant materials, ensuring longevity and robustness even in harsh environments.
2. Easy Installation: The drain features a simple, one-piece design, making installation relatively straightforward. In addition, its self-centering, vertically adjustable float mechanism ensures proper positioning and alignment during installation.
3. Effective Draining: The HDF120A's large 3-inch drain outlet facilitates efficient and quick draining. Its adjustable float allows for precise control of drainage levels and helps maintain optimal operating conditions.
4. Cost-Effective: Compared to other drain systems, mechanical float drains like the Parker HDF120A offer competitive pricing. Their simple design and continual drainage during float operation prevent waste of resources or energy for constant pumping.
Cons:1. Limited Automation: Mechanical float drains like the Parker HDF120A lack the automation of electric or air-operated drains. They rely on gravitational forces and remain passive, making them less suitable for continuous or automated applications.
2. Limitations for Dirt and Debris: The mechanical operation of the drain limits its ability to handle large amounts of dirt, sediment or debris without requiring frequent cleaning or maintenance. Anything that may clog the float, valve or drain outlet may prevent proper drainage.
3. Limited Range: The range of applications for a mechanical float drain like the Parker HDF120A is not as wide as electrical or air-operated drains since their operation is dependent on gravity. They are best suited for shallow drainage systems.
Conclusion:The Parker HDF120A Hiross Mechanical Float Drain is a cost-effective, durable and efficient option for shallow drainage applications. Its simple design ensures ease of installation and requires minimal maintenance. Despite its limitations in terms of automation, handling of debris, and drainage depth, its advantages make it a popular choice for those requiring a reliable and affordable drainage solution.
Recommendation:If your application requires shallow drainage with minimal automation, and you can handle occasional cleaning to maintain optimal performance, the Parker HDF120A Hiross Mechanical Float Drain is an excellent choice. However, if you need deeper drainage, frequent automation, or are dealing with frequent debris, consider electric or air-operated drain options.
