Multistage step-down regulating valve
 

FLOWSERVE multi - stage step-down control valve is a multi - stage sleeve pressure reduction control valve. The valve body adopts s-shaped flow channel design, with small fluid resistance and large flow capacity. The valve core is designed with balanced structure, stable adjustment and strong pressure tolerance. According to the pressure difference between the front and the back of the valve, 1 to 3 grade sleeve is adopted to reduce pressure, effectively avoiding flash evaporation and cavitation. This product is mainly used for liquid and gas high pressure difference, easy to flash evaporation, cavitation erosion.
