Boiler accident drain valve

It can be used for large and medium-sized generator sets to control the liquid level of the boiler drum within the specified range. It is one of the key valves in thermal power plants. It can also be manually controlled and used as a high-pressure differential shut-off valve. It can also be used in petroleum and chemical systems. Controls high differential pressure fluids.

Technical data:

-Pressure: PN250-420
ANSI Class 900-2500
-Connection standard: RF, RJ, BW, lens pad -Temperature: -20~+420℃ -Flow characteristics: Switch two position -Leakage: Class IV

Material:

-Valve body: 20# forging
– Trim: stainless steel nitride hardened

Optional:

none

Features:

-Forged angle type, Z type valve body
-The fluid is depressurized step by step, and the direction of the fluid changes continuously. Increase the flow resistance, control the flow rate, and prevent the fluid from cavitation damage. The allowable pressure difference in the valve is 25MPa
-Multi-stage throttling design
-The throttling surface is separated from the sealing surface, and the surface is hardened with a solid particle anti-seize design
