I. Core Structural Features
- Connection and Sealing ：The valve body uses Flange connection (Conforms to GB/T 9119 national standard), convenient installation for pipeline systems; the sealing form is Diaphragm soft seal (Nitrile rubber diaphragm), when closed, the sealing performance meets the sealing test requirements of GB/T 13927, ensuring zero leakage of the medium.
- Float linkage control ：Through Stainless steel float + copper pressure guiding tube Realize hydraulic drive (the float assembly is visible on the right side of the picture), the float adjusts the main valve opening with the rise and fall of the liquid level, automatically controls the water pool/water tower water replenishment (conforms to the GB/T 18145 float valve national standard logic), the liquid level control is accurate and not affected by water pressure.
- Manual emergency operation ：The left red hand wheel manual valve supports Emergency switch/debugging ，Ensuring system controllability under complex conditions and improving the reliability of the valve group.
- Pressure transmission ：The copper pressure guiding tube connects the valve body and the float assembly, accurately transmits the medium pressure signal, and ensures the response speed of the float linkage.

F745X diaphragm remote control float valve
The F745X diaphragm remote control float valve uses a flange connection and integrates three core functions: diaphragm soft seal, float hydraulic linkage, and manual emergency operation. It conforms to national standards such as GB/T 12238 and GB/T 13927.
It automatically adjusts the main valve opening according to the rise and fall of the float, achieving precise water replenishment for water pools/towers without being affected by water pressure. The manual valve supports emergency operation, flexible installation, and reliable sealing.
Suitable for water supply and drainage, fire protection, and construction fields with pipelines ≤ DN450, providing a dual-control water replenishment solution with automation + emergency protection for fluid systems.
