High Pressure Needle Valve

Specifications and Description High Pressure Needle Valve

High pressure valves play a crucial role in many industries. It controls pressure in hydraulic systems. High pressure needle valves handle extreme temperatures and pressures. It manages clean gases and liquids effectively.

Brass needle valves work with drinking water and non-reactive fluids. Stainless steel valves resist corrosion and high temperatures. It handles high-pressure liquids well. HPNV valves operate at pressures from 15,000 to 60,000 PSI. These compact valves fit in tight spaces and on test benches.

The valve spindle doesn’t rotate, preventing seizing even with infrequent use. The blow-out-proof design ensures safety under high pressure. Users can fully open or close the valve in five turns—a mechanical stop guards against accidental loosening. The self-centering system makes assembly quick and easy. High-quality seals and innovative design lead to long-lasting performance. These valves maintain tightness over time and withstand frequent pressure changes and high loads.

Key Features of High Pressure Needle Valves

Precision-engineered for reliability: Each valve undergoes strict testing to BS6755 / ISO 5208 leak rate A standards. This meticulous engineering ensures exceptional performance and minimal leakage in demanding environments, instilling confidence in their reliability.

Versatile design options: Various materials and configurations are available, empowering operators to choose the best fit for specific industrial applications, from oil and gas to aerospace.

Effortless operation: The valve handle turns smoothly with low torque, providing precise control even under high pressure. This feature enhances operator safety and efficiency, making the operator feel at ease with the product.

Extended service life: The non-rotating spindle head design minimizes wear within the housing. This innovative approach significantly extends the valve’s operational lifespan, reducing maintenance needs and downtime.

Tailored instrumentation solutions: Customers can request specific valve and instrument combinations. This customization allows for optimized system integration and improved process control in specialized applications.

Corrosion-resistant construction: High-quality materials like stainless steel resist corrosive media. This feature ensures long-term reliability in harsh chemical and marine environments.

Applications of High Pressure Needle Valve

High pressure needle valves is a versatile tool that effectively control circuit pressure, balance weight, and external forces, and connect to the cylinder’s rod end. It uses a pressure setting slightly above the minimum, preventing loads from falling freely.

Many industries rely on these valves. Machine builders use it for precise automation. Oil and chemical companies depend on its accuracy. Injection systems need it for proper function. Test benches use it for reliable results. Hydraulic power packs incorporate it for smooth operation. It plays a key role in blow-out prevention systems.

It manages high pressures in wet sandblasting operations, cut processes employ it for precise control, and high-pressure cleaning systems rely on its sturdy design. The oil and gas sector faces extreme conditions, and these valves handle intense pressures in drilling and extraction.

Needle valves excel in demanding tasks. It controls flow in tight spaces, and its compact design fits nicely on crowded control panels. Engineers value their reliability in critical systems. These valves perform consistently in harsh environments, effectively resisting wear and corrosion.

How to use?

• Install the valve in the correct orientation, ensuring it aligns with the flow direction indicated by the arrow on the valve body.
• Securely connect the inlet and outlet ports to the appropriate piping or tubing, using the correct fittings and ensuring no leaks.
• Before pressurizing the system, ensure the valve is closed, which can be done by turning the handle clockwise until it stops.
• Gradually open the valve by turning the handle counterclockwise. Open the valve slowly to control the flow rate and prevent sudden pressure surges.
• Fine-tune the valve to achieve the desired flow rate or pressure. The needle design allows for precise adjustments.
• To stop the flow, turn the handle clockwise until fully closed.
• Regularly check the valve to avoid wear, leaks, or damage. Ensure the spindle and seals are in good condition.
• Clean the valve components to remove any debris or buildup affecting performance.
• Apply appropriate lubrication to the spindle and moving parts to ensure smooth operation.

Safety Guidelines

• Wear Safety Gear: Use gloves and goggles to protect from high-pressure fluids.
• Check Pressure Ratings: Ensure the valve matches the system’s operating pressure to prevent failure.
• Inspect Before Use: Look for signs of wear or damage before operating the valve.
• Install Correctly: Follow the flow direction indicated on the valve body when installing.
• Open Slowly: Turn the handle counterclockwise slowly to avoid sudden pressure surges.
• Adjust Carefully: Make precise adjustments to control flow and pressure accurately.
• Close Gradually: Turn the handle clockwise to close the valve gently, stopping the flow.
• Perform Regular Maintenance: Clean and lubricate the valve components for smooth operation.
• Know Emergency Procedures: Learn how to shut down the system quickly in case of a problem.
• Avoid over-tightening: Do not over-tighten the handle to prevent damage to the valve.
