Product Usage:

Applied to automatic control systems for pipelines in military, aerospace, shipbuilding, nuclear, petrochemical, power, chemical, light industry, machinery, scientific research, drying equipment, food, medical, cleaning equipment, and other industries. Suitable for actuators that use steam as a heating medium for automatic temperature control. Two position automatic control and remote control area can be applied to the boiler steam pipelines of steam equipment such as steam heaters, radiators, dryers, as well as various temperature controllers, steam setting machines, steam dyeing machines, steam regain machines, and other complete sets of equipment.

Structural features:

Patent technology and unique design;

The valve core is a stainless steel piston structure with stable performance;

The piston ring is made of special temperature resistant and wear-resistant materials with good sealing performance;

The piston and valve chamber do not produce direct friction, and the service life is ten times that of similar products;

Autocratic coil, not easy to burn;

working principle:

Normally closed type: When the coil is energized, the pilot valve core is attracted, the pilot hole is opened, the upper chamber of the valve is depressurized, the piston is pushed by the pressure of the lower chamber medium, and the solenoid valve is opened; When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston throttle hole and the thrust of the reset spring, and the solenoid valve is closed.

Normally open type: When the coil is energized, the pilot hole closes, and the upper chamber of the valve is pressurized by the piston orifice and the thrust of the reset spring, causing the solenoid valve to close; When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole opens, the upper chamber of the valve is depressurized, the piston is pushed by the pressure of the lower chamber medium, and the solenoid valve opens.

Note: If the pressure at the outlet end is greater than that at the inlet end, the medium will conduct in reverse. Can install check valves or customize valves with built-in check function.
