The valve core are stainless steel piston, piston ring, making low temperature resistant special wear-resistant materials; metalpiston and valve cavity produces no direct friction, the valveinstalled on the direction of unrestricted.
Product features
Special coil, is not easy to be burned; long time stop restart, the same sensitive.
Working principle
Normally closed: when the coil is energized, the pilot spool pull,open the pilot hole, cavity pressure relief valve, pressure to push the piston cavity medium, the electromagnetic valve is opened;when the coil power, the pilot valve by the spring, the pilot hole is closed by the piston, valve chamber orifice booster and a reset spring thrust, the electromagnetic valve is closed.
