Boiler feed water control valve

The sleeve and valve core of the valve inner assembly are a kind of porous and cascade mixed structure. The fluid first passes through the sleeve window for first-stage throttling, and then passes through three-stage continuous cascade throttling, allowing large pressure difference and tightness. Good; the valve is one of the important regulators for boiler feed water systems in thermal power plants, and can also be used in automatic control systems for petrochemical and other industries to control high-pressure differential fluids.

Technical data:

-Pressure: PN250-320
ANSI Class 900-2500
-Connection standard: BW
-Temperature:-17~+420℃
– Flow characteristics: linear or equal percentage – Leakage: V class

Material:

-Valve body: 20# forging
– Trim: Special stainless steel with surface hardening treatment

Optional:

none

Features:

-Forged straight-through interbody
-The large valve assembly has a novel structure and adopts sleeve throttling. Effectively control the flow velocity around 30m/s
-The throttling surface is separated from the sealing surface of the valve seat, which effectively protects the sealing surface, has good sealing performance, and has a long service life. The inner components are made of high-strength stainless steel
-The valve core adopts a pressure-balanced structure to reduce the unbalanced force of the fluid acting on the visual core
