Application

B41DP pilot piston solenoid valve is widely used in military, aerospace, shipbuilding, nuclear industry, petrochemical, electric power, chemical, light industry, machinery, scientific research, industrial furnace, drying equipment, boiler, water supply and drainage, air conditioning, fire protection, food and medical, Cleaning equipment, pipeline media automation and other fields.

Features

Precision casting, beautiful appearance; pilot-type piston structure, stable performance; good sealing, fast switch; auto-made coil, not easy to burn;

Principle

Normally open: When the coil is energized, the electromagnet core is sucked, the pressure relief hole is closed, the main piston is pushed by the medium pressure, the main valve port is closed, and the medium is cut off. When the coil is de-energized, the main valve port opens and the medium circulates.
