A LPG safety valve is a critical safety device used in liquefied petroleum gas (LPG) storage tanks or systems. Its core function is to automatically open when the internal pressure of the container exceeds a preset safe value, releasing part of the medium to reduce pressure and prevent container rupture or explosion due to excessive pressure. It typically employs a spring-loaded design, featuring precise set-point pressure for activation and reliable sealing performance. This ensures it remains tightly closed under normal pressure conditions and responds promptly during over pressure events. As an indispensable component for ensuring the safety of LPG storage, transportation, and usage, the safety valve requires regular calibration and maintenance to guarantee it remains in effective working condition.

Dual Solenoid Valve for LPG dispenser is a critical safety control component. Its core function is to achieve rapid and reliable control of liquefied gas (such as LPG) flow through a dual-coil redundant design. Under normal operating conditions, it responds to electrical signals to precisely open or close the gas supply. If the main coil fails, the backup coil immediately takes over to forcibly cut off the gas source, preventing gas leaks. Its explosion-proof and corrosion-resistant structure is suitable for flammable and explosive environments. Widely used in commercial kitchens, industrial heating systems, and other applications, it provides dual safety protection for gas equipment, significantly enhancing the system's emergency response capability and operational stability.

In LPG solenoid valve is an automatic safety device that controls the opening and closing of a gas pipeline through the energization and de-energization of an electric current. When energized, the valve opens to allow gas flow; when de-energized, the valve closes rapidly under spring action to cut off the gas supply. Its primary function is to ensure safe gas supply during the operation of appliances such as gas stoves and water heaters, and to immediately cut off the gas flow when the appliance is turned off, during a power outage, or upon detection of a leak, thereby preventing accidental gas leakage that could lead to fires or poisoning incidents. It is a critical safety protection component in liquefied gas systems.

The core safety feature of this Breakaway Valve for fuel dispenser is that it automatically disconnects when there is excessive force or overload. This reduces potential safety hazards such as liquefied gas leakage and pipeline damage at the source. It serves as a "safety insurance" for the transportation of liquefied gas. Moreover, it is highly durable, with stainless steel material that combines corrosion resistance and mechanical strength. It is suitable for outdoor and humid environments, and has a longer service life.

The Differential pressure valve for LPG produced by Wenzhou Supertech Machine can precisely control the pressure difference, preventing LPG leakage and equipment damage risks caused by excessive or insufficient pressure. At the same time, it ensures the stability of the medium flow rate and improves the accuracy of subsequent measurement and filling. Moreover, it is compatible with the entire LPG supply chain, and can be quickly connected for use in tank output, pipeline transportation, or terminal filling equipment, without the need for additional modifications.

LPG Dispenser Filling Nozzle of Wenzhou Supertech Machine Co., Ltd. has zero learning curve for operation. It is a one-step, single-action operation. Just by pressing with one hand, the filling process can be initiated. Even beginners can quickly master it. Moreover, it is flexible without any limitations. It comes with a 360° rotating connector, allowing for free adjustment of the angle during the filling process, and it can be adapted to different equipment layouts.
