The needle valve (piston-type regulating valve) is specially designed for precise flow control, energy dissipation, and cavitation reduction under high differential pressure and large flow conditions. It uses a piston-shaped needle to adjust the flow area gradually, enabling linear flow regulation and smooth pressure reduction.

Feature: 
1. Precisely machined stainless steel needle for high splitting accuracy
2. Multi-jet outlet design for effective energy dissipation and cavitation prevention
3. Dual sealing design (metal-to-metal and soft seal)
4. Fully simulated flow channel design for optimized hydraulic performance
5. Multiple actuator options (electric, worm gear, pneumatic, hydraulic)
6. Customizable internal structures for various working conditions
