Boiler feedwater regulating valve DTB

The sleeve and valve core of the valve components are a hybrid structure of porous and cascade. The fluid first passes through the sleeve window for the first stage throttling, and then through three consecutive cascade throttling stages, allowing for a large pressure difference and good sealing performance; This valve is one of the important regulating valves in the boiler feedwater system of thermal power plants, and can also be applied to automatic control systems in other industries such as petrochemicals to control high-pressure differential fluids.

Characteristics

Ø Forged straight through valve body

The internal components of the valve have a novel structure, using sleeve throttling to effectively control the flow rate at around 30m/s

The throttle surface is separated from the valve seat sealing surface, effectively protecting the sealing surface, with good sealing performance and long service life

Ø The components inside the valve are made of high-strength stainless steel

Ø The valve core adopts a pressure balanced structure to reduce the unbalanced force of fluid acting on the valve core
