一、进口带手动控制电磁阀产品概述：

德国《LOCKE》洛克--进口手动控制电磁阀是指电磁阀在电磁开关的基础上，加手动开关控制，在电磁阀实现关闭后，可以手动开启，或者在电磁阀实现开启后可以手动复位，主要特点：在原由的电磁阀阀体上加装手动装置，其目的电磁阀在断电时一个应急开关作用， 经常应用于燃气，紧急切断系统。

1、 Introduction of imported solenoid valve with manual control

Locke imported manual control solenoid valve means that the solenoid valve is controlled by manual switch on the basis of electromagnetic switch. After the solenoid valve is closed, it can be opened manually, or it can be reset manually after the solenoid valve is opened. Its main features are: manual device is installed on the original solenoid valve body. Its purpose is that the solenoid valve can be used as an emergency switch in case of power failure, Most often used in gas, natural gas emergency shutdown system.

三、进口带手动控制电磁阀工作原理：

常开式：阀自动控制时，手动柄必须处于打开状态；线圈失电后，旋转手动柄可控制阀开关。

常闭型：阀自动控制时，手动柄必须处于关闭状态；线圈失电后，旋转手动柄可控制阀开关。

3、 Working principle of imported solenoid valve with manual control:

Normally open: when the valve is automatically controlled, the manual handle must be in the open state; When the coil loses power, rotate the manual handle to control the valve switch.

Normally closed type: when the valve is controlled automatically, the manual handle must be closed; When the coil loses power, rotate the manual handle to control the valve switch.

四、进口带手动控制电磁阀性能特点：

电磁阀线圈失电或烧毁时，可用手动柄实现电磁阀打开和关闭；

操作方便、性能稳定；

活塞结构、密封性好；

特制线圈、不易烧毁。

4、 Performance characteristics of imported solenoid valve with manual control:

When the solenoid valve coil loses power or burns, the manual handle can be used to open and close the solenoid valve;

Easy to operate and stable performance;

Piston structure and good sealing performance;

Special coil, not easy to burn.

Introduction of imported manual control solenoid valve products: Roch-imported Manual Control solenoid valve refers to the solenoid valve on the basis of the solenoid switch, plus manual switch control, after the solenoid valve closed, can be opened manually, or The solenoid valve can be manually reset after the realization of open, the main features: The original solenoid valve body installed with a manual device, the purpose of the solenoid valve in the power off an emergency switch role, most often used in gas, eMERGENCY SHUT-OFF SYSTEM FOR NATURAL GAS. 2. Imported Manual Control solenoid valve technical parameters: DIAMETER RANGE: DN3 ~ DN300 control mode: normally closed, normally open, self-holding power supply voltage: DC12 ~ DC240V, AC220 ~ 380V valve body material: Cast Steel WCB, stainless steel 304/316 applicable medium: water, gas, oil, corrosive fluid pressure range: 0.1 ~ 250MPA temperature range:-50 ~ (+ 120, + 200, + 250) medium viscosity: less than 50C St (more than custom) protection performance: waterproof, dustproof, explosion proof. According to the operating mode selection of wiring: Wiring seat type; lead type; Plug-type connection: thread, Flange, welding (external thread and special interface can be customized or add adapter)3, imported with Manual Control solenoid valve working principle: Normally Open: Valve automatic control, manual handle must be open; After the power loss of the coil, the valve switch can be controlled by rotating the manual handle. Normally closed: When the valve is automatically controlled, the manual handle must be in the closed state; after the coil loses power, the valve switch can be controlled by rotating the manual handle. Four, imported with manual control solenoid valve performance features: SOLENOID VALVE COIL POWER LOSS or burn, can be used to open and close the manual handle; easy to operate, stable performance; Piston structure, good sealing; special coil, not easy to burn.
