A Brief Introduction to HSC Pneumatic Sleeve Control Valves: The HSC series sleeve control valve is suitable for high-pressure differential applications prone to flash cavitation. It is a high-performance single-seat control valve with a robust sleeve protecting the valve body from damage caused by vaporization and cavitation. The valve has a compact structure and an S-shaped streamlined channel, resulting in low pressure drop, high flow rate, and a wide adjustable range.
