FAQ’s
Have a question before you buy our products? Take a look at the FAQs below.
If you don’t find the answer you’re looking for, get in touch with us here.
- What is a High Pressure Needle valve?
- How does it work?
A needle valve operates by rotating the valve stem, which in turn adjusts the position of the tapered needle. As the needle moves closer to or farther from the valve seat, the flow of fluid is regulated, allowing for precise control over flow rates.
- What are the benefits of using one
The advantages of needle valves include their exceptional flow control capabilities, even at low flow rates. They provide fine adjustments, leak-tight shut-off, and the ability to maintain stable pressure conditions, making them essential for processes requiring accuracy and stability
- What are the main applications?
Needle valves are commonly used in applications requiring precise flow control, such as instrumentation and control systems, laboratory equipment, hydraulic and pneumatic systems, and high-pressure and high-temperature applications.
- What materials are used in their construction?
Needle valves are typically constructed from materials such as stainless steel (SS316, SS304), brass, alloy 400, and PTFE (Teflon) for seals and packing.
- How do I choose the right one for my application?
To choose the right needle valve, consider factors such as pressure and temperature requirements, fluid compatibility, end connection type (threaded, flanged, compression, etc.), flow rate and system requirements, and construction material and corrosion resistance.
- Can they be repaired?
Yes, needle valves can often be repaired. However, the repair process may vary depending on the extent of damage and the specific design of the valve. It is recommended to consult the manufacturer or a qualified technician for proper assessment and repair procedures.
- What maintenance is required?
Regular maintenance of needle valves is essential to ensure optimal performance and longevity. Maintenance tasks may include regular inspection for wear and damage, lubrication of moving parts, and replacement of worn-out seals or components as needed.
- Are they available in different designs?
Yes, needle valves are available in various designs to suit different application requirements, including inline needle valves, angle needle valves, integral bonnet needle valves, union bonnet needle valves, miniature needle valves, and hydraulic needle valves, among others.
- Why is Freture the best place to buy Needle Valves from?
Freture is the preferred choice for purchasing needle valves due to rigorous quality control measures ensuring adherence to international standards, precision engineering and customization options to meet specific requirements, global reputation for excellence and reliability in the manufacturing of needle valves, and responsive customer support and technical assistance ensuring a seamless experience for clients.
