Solenoid valve 3/4 inch WZB2 with coil, NO - normally open 149B12408

Solenoid valve, designed for precise control of liquid and gas flow, is a reliable solution for both installers and end-users. Model WZB2 with a diameter of 3/4 inch, equipped with a coil and operating in a normally open (NO) system, is widely used in irrigation systems, industrial automation, as well as in heating and sanitary installations.

Construction and principle of operation

This valve is characterized by a solid construction with a body made of brass CW617N, which ensures high corrosion resistance and long-term operation. Internal elements – the stem and spring – are made of stainless steel, guaranteeing reliable operation even in difficult conditions. The diaphragm and pilot valve plate made of EPDM ensure tightness and compatibility with water. The principle of operation is based on electromagnetic opening and closing of the flow – no voltage on the coil keeps the valve open, while applying voltage closes the valve. A minimum differential pressure of 16 bar ensures stable operation of the device.

Application and benefits

This valve is an ideal choice for systems requiring automatic flow control. Its normally open character makes it particularly useful in emergency applications where maintaining the flow of medium is necessary in the event of a power failure. The Kvs value of 8 indicates good valve throughput, which translates to efficient system operation. Thanks to the IP65 protection class of the coil, the valve can be used even in humid or dusty environments. Installation is simple thanks to internal threaded connections. The coil with a power of 9W powered by AC voltage (230V/50Hz) is supplied in the set, which eliminates additional purchase costs.
