Fire signal gate valve

The signal gate valve for fire protection is sealed and equipped with a reliable O-ring valve stem sealing (reverse sealing) structure, which can confirm that the valve is in a normally open state for a long time and the valve stem does not leak, which is beneficial for installation and use in suspended ceilings

Working principle of signal gate valve: The electrical signal device is a fully enclosed and detailed electromechanical box structure, with stainless steel parts and incoming electrical components inside the box. The device is located on the valve body cover under the operating handwheel, which is not easily collided. Equipped with a micro switch and its driving mechanism, the gear meshes with the gear fixed on the valve stem for transmission. When the handwheel is turned to open and close the gate valve, the signal device outputs the corresponding position of the gate valve opening and closing; Tong "& quot; Cut off "; Electric signal. When a 24V voltage is input and the valve is closed to 1/4 of its full open position, the signal that the valve is closed can be transmitted to the control center. The signal gate valve has signal output during the stroke of the valve from fully open to fully closed. Signal device input voltage 24V AC or DC power supply

Fire signal gate valve XZ45X Performance characteristics:

① Integral encapsulation: The gate adopts integral encapsulation, which has good coverage performance and accurate geometric dimensions, protects excellent sealing performance, and has a long service life

② Lightweight: The valve body is made of ductile iron, which is lightweight and easy to install③ Flat bottomed valve seat: The valve seat adopts the same flat bottomed design as the water pipe, which does not produce debris accumulation and has excellent sealing

④ Corrosion resistance (based on actual reports) (based on actual reports) (based on actual reports) (based on actual reports) (based on actual reports) (based on actual reports): The inner cavity is coated with toxin detection epoxy resin to prevent corrosion and rust, which can not only be used for drinking but also for sewage systems

⑤ Three "; O" Sealing: The valve stem adopts three O-rings for sealing, with low friction resistance, lightweight switch, and no water leakage
