GQC-5 electromagnetic high vacuum inflatable valve GQC-5 filling the vacuum solenoid valve is a high-powered electromagnetic force, when the power is turned on, the valve is closed, the vacuum system is isolated from the atmosphere; after power off, the valve is turned on, the atmosphere subsequently filling the vacuum system. Applicable medium can be pure air or corrosive gases. The main technical performance Nominal by: 5mm Scope: 105 ~ 6.7x10-6Pa valve leak rate: ≤1.3x10-6 Pa.L / S Temperature: -30 ~ + 80 ℃ coil temperature: ≤65 ℃ switching times : ≤60 beats / min Power: Default: 220V / 50Hz Specially Designated: AC110V, DC24V installation status: Any major parts materials Body: aluminum or stainless steel Seals: NBR shape and connection dimensions (mm) (GB4982 / ISO-KF)
