Overview
TianKang HongJi Ultra High Pressure Needle Valve with Actuator 20,000 psi 1" is a high-precision flow-control valve engineered for demanding systems operating at extremely high pressures, typically above 10,000 psi and up to 20,000 psi. Designed for accurate regulation of liquids and gases, this model is equipped with a compact small-cylinder pneumatic actuator, providing fast response, stable operation, and reliable remote control while significantly reducing manual handling under harsh conditions. The small-cylinder actuator delivers consistent needle positioning and excellent throttling accuracy even in fluctuating pressure environments. With its robust construction and high-pressure resistance, this valve is widely used in oil & gas testing, chemical process systems, aerospace hydraulics, and other applications requiring precise, safe, and efficient control of ultra-high-pressure media.
