Magnetic locking gate valve

Brand：Pneumatic eccentric butterfly valve 型号：JMZ45X-16Q

Magnetic locking gate valve is an anti-theft valve device that is controlled to open and close by magnetic force. It is mainly used for terminal management of water supply, heating, gas and other pipeline systems to prevent unauthorized operation or theft. The following are its core features and functions:
Structure and Working Principle
Composition: It consists of a valve body, a lock head, a spring, a magnetic pin, and a valve stem. The lock head side is equipped with a spring hole, which houses a spring that supports the magnetic pin. The key end is equipped with a corresponding magnetic pin for matching control.
Opening and closing mechanism: A dedicated key (marked with a "C" shape) needs to be inserted into the lock head, and the valve can only be operated after the magnetic pin phase matches; Without authorization, the lock will idle to prevent violent damage.
Material and Performance
Material: mostly made of brass or ductile iron, coated with epoxy resin anti-corrosion coating on the inside and outside, suitable for medium environments ranging from -20 ℃ to 80 ℃.
Sealing design: The soft seal gate is combined with the flat bottom valve seat, and the overall rubber structure ensures zero leakage, low flow resistance, and anti clogging.
Application scenarios
Fields: Front valves for water meters, heating systems, gas pipelines, and solar water heaters.
Anti theft function: self-locking is achieved through magnetic pole coding technology, and only a dedicated key can be used to switch it on and off, effectively controlling issues of arrears or theft.
Installation and maintenance
Installation direction: The arrow on the valve body should be consistent with the water flow. It is recommended to install a flexible joint for easy maintenance.
Special opening: When keyless, the magnetic point can be positioned by a magnet in conjunction with the stethoscope operation, but it requires professional personnel to complete.
Model and standard
Common models: JMZ45X-16Q, SZ45X, etc., comply with industry standards such as CJ/T 216-2005.
Additional features: Some models support expansion requirements such as opening indication and underground direct burial.
