At present, the electric insulation ball valve produced by the valve manufacturer brass solenoid valve manufacturer is mainly used in various systems such as petroleum, chemical, pharmaceutical, food, etc., for conveying high-viscosity media that will solidify at room temperature. Even when the external temperature drops below zero, the electrically insulated ball valve can operate flexibly, ensuring that the oil pipeline can be disconnected. Its advantage is that there are no general control valves. It is ideal for brass solenoid valves, water pipe solenoid valves, and heavy oil pipelines. Control valve.

Electrically insulated ball valve

Installation steps of electrical insulation ball valve:

First remove the protective covers on both sides of the flange head, and rinse them with the valve fully opened.

Before installation, the whole machine should be tested according to the specified signal to prevent the performance of the machine from being affected by the conveying vibration. It can be installed online only after it is qualified. The wiring must be in accordance with the electric actuator circuit diagram.

Before preparing to connect to the pipeline, it is necessary to clean and remove the remaining impurities in the pipeline, because these impurities may damage the valve seat and valve ball.

4. During the installation process, do not use the refrigeration solenoid valve actuator part of the valve as a lifting point to avoid damage to the actuator and accessories.

Should be installed in the vertical or horizontal direction of the pipeline.

The pipeline near the installation point must not sag or bear external forces. Supports or pipeline brackets can be used to prevent the pipeline from deviating.

After connecting with the pipeline, please cross-tighten the flange connecting bolts with the specified torque.

In order to prevent foreign matter such as sand particles in the metal from entering the inside of the valve and damaging the sealing surface, when installing the electric insulation ball valve, a filter and a flushing valve must be installed in front of the valve; in order to maintain the balance of compressed air and purified air, it must be installed in front of the valve Oil-water separator, or air filter; in order to check the working state of the valve during operation, it is necessary to set up instruments and check valves; to maintain the temperature when operating the electric insulation ball valve, insulation facilities can be set outside the valve; to install the valve after installation safety Valve or check valve; considering the continuous operation of the valve, it is convenient for the occurrence of danger, so a parallel system or bypass system is set up.
