Detail Information

Product Name: Card Sleeve Needle Valve
Body Material: Stainless Steel SS 316
Pressure: 6000 PSI
End Connection: Double Sleeve NPT Thread

The high-pressure card sleeve needle valve is a precision control valve designed for fine-tuning the flow rate. It features a needle-shaped valve plug, primarily used to adjust throttle flow rates with high accuracy. This valve allows for gradual and continuous adjustment of the valve opening, from fully closed to a larger opening.

The needle valve plug, typically made from quenched steel or stainless steel, ensures tight sealing with the valve seat. The valve seat is often made from soft materials such as tin and copper to achieve a reliable seal. The imported SS-1RS8 needle valve uses a conical surface to create the sealing between the valve plug and seat. The needle’s taper comes in two standard cone angles: 1:50 and 1:60, both requiring fine grinding to ensure optimal performance. Additionally, the sealing between the valve stem and valve seat is achieved through the use of corrugated pipes.

This valve is ideal for applications requiring precise flow control and is commonly used in high-pressure environments.
