Typical Outline Drawing 典型外形图 Product Specifications 产品特点 Adopting Eng. thread quick connector (copper flare connection) or brass tube welding fitting structure, flexibly setting, easy to use and no special need for mounting and fixing . Plugging or wiring connection designed to customers’ choice. SPST connection, normal open or normal close structure to customers’ choice. Security and reliability by adopting fusion welding stainless steel pressure inductor and full air-tight connection. Any pressure value within 3~800 PSI (0.02~5.5MPa) can be made based on customers' requirement. Pre-set pressure parameter before delivery allows direct use without resetting on the customers’ site. 采用英制管螺纹快速接头或铜管焊接式安装结构，使用方便，安装灵活，无须特殊的安装固定。 插片式或导线式连接方式可供用户任意选择。 单刀单掷型开关方式，常开式或常闭式开关接点结构可供任意选择。 熔焊密封式不锈钢压力感应器和全密封开关结构安全可靠。 在3～800PSI(0.02～5.5 Mpa)压力范围内可根据用户要求任意选定压力值进行制造。 产品在出厂前其压力参数在工厂已按要求设定好，无需再设定，可直接使用。 Operating Principle 工作原理 The series of pressure control are made based on the theory that an inside reversible stainless steel motion diaphragm turns over when inducing certain pressure. The electric contact opens or closes with the leader when the diaphragm moves. The switch resets automatically when induced pressure reduces below rated value. 该系列压力控制器主要利用内置的不锈钢可翻转动作膜片在感应到一定压力后可向反方向翻转的特性进行制造。当膜片动作时，会通过一个导杆带动电气触点 的吸合或打开。当感应压力降低至恢复值以下时，开关即可自动复位。 工作压力范围：3～800PSI（0.02～5.5MPa） 爆破压力：5000PSI 环境温度：-30℃～+80℃ 系统介质温度：-50℃～+120℃ 额定电流下的寿命次数：30,000次，50,000次，100,000次可供选择 电气规格：24Vac 时常规电气容量125VA 120/240Vac时常规电气容量375VA 抗电强度：断开触点间为AC700V/S，端子对外壳为AC2000V/S 安全耐压：压力控制器可承受的不影响动作设定值的压力。 The highest range of working pressure 最高工作压力范围 Safety proof pressure 安全耐压 <145PSI(1MPa) 250PSI(1.7MPa) 145PSI(1MPa)~400PSI(2.75MPa) 600PSI(4.1MPa) >145PSI(2.75MPa) 800PSI(5.5MPa) ◆ Working pressure range: 3~800PSI（0.02~5.5MPa） ◆ Burst Pressure: 5000PSI ◆ Ambient temperature: -30℃~+80℃ ◆ System medium temperature: -50℃~+120℃ ◆ Life cycles under the rated electric current: 30,000 times, 50,000 times and 100,000 times optional ◆ Electrical Rating: At 24Vac, normal electric capacity: 125VA At 120/240Vac, normal electric capacity: 375VA ◆ Dielectric Strength: Between disconnected contacts: AC700V/S Terminal to outer shell: AC2000V/S ◆ Safety proof pressure: The pressure that the control can endure while not affects the rated motion value C H C H Normal Close 常闭型 Normal Open 常开型 Typical Structure Drawing 典型结构图 Application 用途 The series of pressure control are used to the high, low pressure protection of some refrigeration system like residential, commercial, automobile air-conditioner and ice maker etc. It can also be used to hydraulic pressure and steam pressure control system of all kinds of air compressor, equipment or tool and agricultural machine. 该系列产品主要用于家用、商用、汽车空调、制冰机等制冷系统中的高、低压力保护控制，也可适用于各种空压机、设备工具、农用机械的液压和汽压的控制 系统中。 Electric Theory Drawing 电气原理图 YAKu tSoe- Rr ieesseSt i Pn rgel es sCuurte SCionng tl er oTl h r o w e r YK系列单刀单掷自动复位压力控制器 (YK-01H YK-02H YK-03H YK-01L YK-02L YK-03L) Designed Parameter 设计参数 1
