JD745X Diaphragm Multi-function Water Pump Control Valve

The JD745X diaphragm multi-function water pump control valve integrates check, water hammer elimination, and flow control functions. It uses hydraulic drive and soft sealing structure, conforming to national standards such as GB/T 12238. Suitable for water supply and drainage systems below DN600, it automatically responds to water pump start-stop conditions, effectively suppressing water hammer, and features high flow rate and low pressure loss. It is widely used in building, municipal, and industrial fields to improve the safety and reliability of water supply systems.

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.

YX741X diaphragm adjustable pressure reducing valve

The YX741X diaphragm adjustable pressure reducing and regulating valve uses flange connection and integrates four core functions: diaphragm soft sealing, hydraulic pressure reduction, pressure regulation control, and pressure monitoring. It conforms to national standards such as GB/T 12238 and GB/T 13927. It automatically adjusts the medium pressure through hydraulic drive, manually calibrates the pressure threshold, and the pressure gauge monitors the system pressure in real time. It features reliable sealing and precise control. It is widely used in water supply and drainage, construction, and industrial circulating water systems, providing double protection of pressure stability and pressure reduction for fluid systems.

AX742X diaphragm safety relief pressure valve

The AX742X diaphragm safety pressure relief valve uses a flange connection and integrates four core functions: diaphragm soft sealing, pressure relief and pressure holding dual control, pressure monitoring, and impurity filtration. It conforms to national standards such as GB/T 12238 and GB/T 13927. It automatically responds to pressure changes through hydraulic drive, manually calibrates the pressure threshold, and the filter component ensures the cleanliness of the valve group. It features reliable sealing and precise control. It is widely used in water supply and drainage, fire protection, industrial circulating water, and other fields, providing double protection of overpressure protection + pressure stability for fluid systems.

J145X diaphragm type electric remote control valve

The J145X diaphragm electric remote control valve uses flange connection and integrates four core functions: diaphragm soft seal, electric remote control, manual emergency, and Y-type filtration. It conforms to national standards such as GB/T 12238 and GB/T 13927. It uses an electromagnetic valve to receive electrical signals to drive the diaphragm, achieving automatic on/off control of the medium; the manual valve supports emergency operation, and the filter component ensures the cleanliness of the valve group. It is widely used in water supply and drainage, sewage, construction, and industrial circulating water, providing a dual-control solution of automation + emergency protection for fluid systems.
