High Pressure Needle Valve from us at a low price range.
Exceptional Pressure Handling and Leak Proof PerformanceDesigned for high-pressure applications, this needle valve ensures secure and leak-free operation with its bubble-tight shutoff feature. The adjustable gland packing and precision-machined stem threads minimize the risk of leakage, providing reliability in demanding gas, steam, water, or oil systems. Corrosion-resistant body finishes further enhance its durability, making it a dependable choice for critical pressure control tasks.
Customizable Options for Diverse ApplicationsThe valve comes in multiple sizes (1/8 inch to 1 inch) and offers several handle styles, body finishes, and sealing materials, suiting a range of industrial environments. Choose between integral or screwed bonnets, and select end connections (NPT/BSP) to fit your system. These options allow optimal integration into new or existing instrumentation and process setups requiring precise and manual flow regulation.
FAQs of High Pressure Needle Valve:
Q: How do I choose between the T-bar handle and the round knurled handle for my application?
A: The handle choice depends on operator preference and installation requirements. The T-bar handle offers a better grip for turning under higher torque, which is ideal for higher pressure conditions. The round knurled handle allows for fine adjustments in tighter spaces or for applications where precise control is essential.
Q: What benefits does the quarter-turn open/close operation provide?
A: A quarter-turn operation simplifies valve actuation, allowing for rapid and straightforward on/off or flow adjustment. This feature is especially beneficial for frequent operation or when quick shutoff is needed in high-pressure environments.
Q: Where can this high pressure needle valve be used?
A: This valve is suitable for use in instrumentation panels, process systems, and high-pressure lines in industries such as oil & gas, chemicals, power plants, and laboratories. It is designed to handle water, oil, gas, air, and steam as media.
Q: What is the process for ensuring leak-proof operation in this valve?
A: Leak-proof performance is achieved through precision-machined, non-rotating stems and adjustable gland packing with PTFE or Graphite. These features offer bubble-tight shutoff, reducing the likelihood of any leakage under high pressure conditions.
Q: When should I opt for an electropolished or passivated body finish?
A: Electropolished or passivated finishes are recommended for applications requiring enhanced corrosion resistance, cleanliness, or where the valve will be exposed to aggressive media. These finishes improve surface quality and are commonly specified in critical process environments.
Q: What is the advantage of bubble-tight shutoff in high pressure needle valves?
A: Bubble-tight shutoff prevents even the smallest leaks, ensuring safe, efficient, and reliable operation in high-pressure systems. This reduces material loss, environmental impact, and maintains process integrity.
Q: How do I mount this valve on a panel, and is panel mounting available for all sizes?
A: Panel mounting is available on request for most sizes. To mount, a retaining nut secures the valve body to the panel, allowing easy operation and maintenance. Check specifications or consult the supplier for availability with specific sizes.
