特殊型工作原理:通電打開時(可長期通電),按下起動按鈕閥打開,發(fā)生報警時或停電時閥關(guān)閉。
German TEK Valves (International) Co., Ltd. - Guangzhou distributor
imported gas emergency shut off solenoid valve (normally open power-off the manual reset open) technology leader secure energized momentarily quick disconnect Phychopsis corrosion resistant piston to use the brand: German TEK range of applications of industrial furnaces, burners, incinerators, gas heating equipment, boilers, fuel supply security, gas leakage alarm systems, fire emergency shutdown systems, gas pipelines, gas processing plants, gas stations, safety protection system, widely used in various types of pipe network security protection, before the accident, The quick disconnect valve, in time to stop fatal accidents. Technical Parameters Nominal diameter DN20-DN350 principle structure direct-acting, step direct acting, pilot-seal material NBR, FKM Body Material SS304, ductile iron casting, some optional WCB Ambient temperature -30 ℃ ~ +60 ℃ (explosion-proof -20 ℃ ~ +40 ℃) Applicable fluid gas, natural gas, liquefied petroleum gas, biogas, fuel and other fluid viscosity ≤ 22mm2 / S (50mm2 / S The following can be special) Connection internal thread, flange-mounted horizontal installation ( Do not tilt or inverted), stem up common type of protection class IP54, explosion-proof IP65 response speed 1 ~ 3S, depending on pressure and control aperture size varies normally open, energized instantly shut; manual reset open fluid temperature C1: -20 ℃ ~ +60 ℃; C3: -10 ℃ ~ +120 ℃ Electrical specifications Supply voltage 220V 110VAC50/60Hz24V 12VDC special AC 50/60Hz: 380V110V48V36V24VDC: 220V, 110V, 48V, 12V rated power parameters table for voltage tolerance ± 10% Electrical connections General type: standard junction box Ex: M16x1.5 internal thread, aside 1.5M wire (can be customized G1 / 2 or NPT1 / 2) Options Code Name Function Description E Explosion-proof grade: Ex d Ⅱ CT4/T5DA double-acting control two coils are controlled opening and closing works: When the solenoid valve to be opened by hand pull handle, solenoid valve opens; when the coil is energized momentarily when (delay power does not exceed 30 seconds), the solenoid valve handle reset, the solenoid valve is closed. Turn off the power when the solenoid valve, press the manual button solenoid valve is closed (the valve must have a manual function). Special type of works: power is turned on (can be long-term power), press the start button valve is opened, an alarm occurs when the valve is closed or power outage.
