Internally Pllot-Actuated Type 4V120-06

  Internally Pllot-Actuated Type 4V120-06

4V120-06 Blocked by controlling the movement of the valve body hole or leak out different discharge of oil, the oil hole is always open, hydraulic fluid will enter the different oil drain, and then through the Pneumatic Solenoid Valve of the oil pressure to push the cylinder piston, the pneumatic Solenoid Valve control through the magnet current electromagnetic valve to control the whole mechanical movement.

The Operating Principle of 4V120-06

There is a closed cavity in the pneumatic solenoid valve, in different positions open through holes, each hole of the pneumatic solenoid valve is to a different trachea, the middle of the cavity is the valve, two sides are two electromagnet, which side of the magnet coil energized valve body will be attracted to which side;

Pneumatic solenoid valve to control the movement of the valve body to blocked or leakage of different exhaust hole, and the air inlet is always open, high pressure gas will enter different exhaust pipe, and then through the pneumatic pressure to push the cylinder piston of solenoid valve, pneumatic solenoid valve control through the electromagnet so current electromagnetic valve to control the whole mechanical movement.

The Material

1. The material of valve body shall be mainly nodular cast iron, and the actual physical and chemical testing data of cast iron shall be marked.

2, stem material, strive to stainless steel stem (2CR13), large diameter valve should also be stainless steel embedded stem.

3, nut material, cast aluminum brass or cast aluminum bronze, and the hardness and strength are greater than the stem.

4, stem liner material, its hardness and strength should not be greater than the stem, and in the case of water immersion and stem, valve body does not form electrochemical corrosion.
