I. Vacuum treatment for solenoid coil to eliminate harmful impurities, it makes the pilot work more sensative and reliable;
II. Orifice and unloading port match with the pulse valve, fast opening and closing, so it increases the blowing volume per unit time;
III. Membrane: Effective bonding and Sufficient tensile strength, Reliable sealing, Great anti-corrosion and anti-aging properties, we are the only company in China to use high-performance diaphragm so that it ensures long-term operation reliability. The company which provide us diaphragms also supply diaphragm to GOYEN and ASCO valve, it’s the same supplier. We guarantee at least 1millon times of service life(5 years).
IV. We are using high-quality pressure spring to guarantee at least 1millon times of service life.
