B11PT Pilot piston solenoid valve

Application

B41D pilot piston solenoid valve is widely used in the fields of militaryindustry, aerospace, shipbuilding industry, nuclear industry,petrochemical industry, electric power, chemistry, light industry,machinery, scientific research, industrial kilns, drying equipment,boilers, water supply and drainage, air conditioning, fire fighting, foodtreatment, cleaning equipment, automatic control of pipeline media, etc.

Features

Precision casting, beautiful appearance; The structure andperformance of the pilot piston are stable. Good sealingperformance and quick switch. Autocratic coil, not easy to burn;

Principle

Normally closed: when the coil is energized, the electromagneticcore is attracted, the pressure relief hole is opened, the main piston. is pushed by the medium pressure, the main valve port is opened,and the medium circulates. When the coil is de energized, themain valve port is closed and the medium is cut off.Normally open: when the coil is energized, the electromagneticcore is attracted, the pressure relief hole is closed, the main pistonis pushed by the medium pressure, the main valve port is closed,and the medium is cut off. When the coil is de - energized, the mainvalve port opens and the medium circulates.
