Product details

A Brief Introduction to HSC Pneumatic Sleeve Regulating ValveThe HSC series sleeve regulating valve is suitable for situations where flash evaporation and cavitation are prone to occur in high-pressure differential stages. It is a high-performance single seat regulating valve with a sturdy sleeve to protect the valve body from damage caused by valve evaporation and cavitation. The valve has a compact structure with S-shaped channels, which reduces pressure drop loss, increases flow rate, and has a wide adjustable range.
