Definition of Ultra-High Pressure Needle Valve

The ultra-high pressure needle valve adopts a non-rotating valve core structure, which completely eliminates rotational wear between the valve core and the valve body. During operation, the valve core and valve seat only move up and down linearly, ensuring the position of the sealing line stays unchanged with each on-off action. This specialized design delivers exceptional sealing tightness and extends the overall service life of the valve significantly.

It is equipped with a dedicated compressed gasket nut design, which ensures more reliable external sealing and eliminates the risk of external medium leakage. The valve needle is processed through special technical treatments, featuring high hardness, outstanding durability, and resistance to damage under extreme pressure conditions. The valve supports flexible installation options, including panel mounting and bracket mounting, to adapt to different pipeline and equipment layout requirements.

Structural Design of Ultra-High Pressure Needle Valve

• High-Strength Valve Body: The valve body is constructed from cold-drawn stainless steel, offering excellent structural rigidity and pressure resistance for ultra-high pressure working conditions.

• Diversified Body Configurations: The valve body is available in three different standard designs, all paired with a precision V-type valve needle for precise flow control.

• Metal-to-Metal Sealing: Adopts a reliable metal-to-metal sealing type, which provides superior sealing performance and prolongs the service life of both the valve needle and valve seat.

• Non-Rotating Valve Needle: The non-rotating design of the valve needle effectively prevents wear and tear on the valve seat, maintaining stable sealing performance over long-term use.

• Wide Media Compatibility: Suitable for use with both gas and liquid media, making it highly versatile for various industrial applications.

• Full Traceability: Equipped with comprehensive traceable record data, including lot number, maximum pressure rating, material model, and product type name for quality management and tracking.

• Standard Supporting Accessories: Each ultra-high pressure needle valve comes standard with a matching threaded sleeve and retaining ring for secure and stable installation.
