Product Description

J661Y P91 High Temperature High Pressure Pneumatic Drain Globe Valve
Product Description

J661y P91 High Temperature High Pressure Pneumatic Drain Globe Valve
1.This series of valves is used for the boilers' periodic and continuous sewerage system in thermal power plants; the power station's water delivery system and water discharge system.

2.The main seal uses the same material to ensure the same coefficient of thermal expansion, to ensure the seal and prevent bite; the main seals are hardened, high hardness, wear resistance, erosion resistance, long service life.
3. The back pressure of the throttling device achieves the purpose of pressure regulation by adjusting the number of throttling cylinders and the orifice of the throttling orifice in the throttling cylinder.
4. The high temperature resistant spring provides continuous sealing thrust between the valve disc and the valve seat and is maintained sealed by the line pressure.
5. Pneumatic + manual drive, safe and reliable, once the automatic control fails, the valve can be actuated by manual drive.
