The 600X electric ductile iron hydraulic control valve consists of a main valve, solenoid valve, needle valve, ball valve, micro filter, and pressure gauge to form a hydraulic control connection system. Remote control of valve opening and closing can be achieved through electromagnetic pilot valves. After installing additional devices, the speed of opening and closing can be controlled. This product uses a pilot valve to control the opening and closing of the valve, saving energy. Can replace other large electric devices for valves.
When the valve supplies water from the inlet end, the water flows through the needle valve into the main valve control room. When the solenoid valve is opened, the water in the control room flows out through the solenoid valve and ball valve. The opening of the ball valve is greater than that of the needle valve, and the pressure in the control room of the main valve is very low. The main valve is in a fully open state. When the solenoid valve is closed, the water in the control room of the main valve cannot flow out. The control room increases the pressure and pushes the diaphragm to close the main valve.

Installation and maintenance
The main valve should be installed on the inlet pipe of the water tank or high water level water tower. The best installation method is to install it horizontally on the pipeline with the valve cover facing upwards. Other installation methods can also achieve the operating function. Pay attention to the flow direction indicated by the arrow outside the main valve body and install it in the correct direction. After installation, ensure that there is no pipeline stress acting on the valve body and internal components.
Before installation, the debris inside the pipeline should be thoroughly removed, and the pipeline system should be thoroughly flushed before water supply.
A gate valve and a filter should be installed in front of the main valve, and a gate valve should also be installed behind the valve for easy maintenance.
When testing the water, slowly open the gate valve in front of the main valve to increase the pressure, and pay attention to whether the control pipeline outside the valve body is leaking.
The micro filter on the main valve conduit should be cleaned regularly every 2-3 months.
Main valve maintenance instructions
The hydraulic control valve itself is a water self lubricating valve body that does not require additional oil lubrication. If the internal parts of the main valve are damaged, please follow the following instructions for disassembly. (Note: The commonly vulnerable consumables inside the main valve are the diaphragm and O-ring, and other internal metals are rarely damaged.)
Close the front and rear gate valves of the main valve first.
Loosen the piping joint screws on the main valve cover to release the pressure inside the valve.
Remove all screws, including necessary copper pipes and nuts in the control pipeline.
Remove the valve cover and spring.
Remove the shaft core, diaphragm (piston), etc., and do not damage the diaphragm.
After removing the above items, check whether the diaphragm and O-ring are damaged. If they are not damaged, do not disassemble their internal parts again.
If damage is found on the diaphragm or O-ring, please loosen the nut on the shaft core, disassemble the worship plate or sealing gasket piece by piece, and replace it with a new diaphragm or sealing gasket after removal.
Thoroughly inspect the valve seat and shaft core inside the main valve for any damage. If any other debris is found inside the main valve, clean it out.
Assemble the replaced parts in reverse order and install the main valve, paying attention to the valve not being stuck.
Please refer to the installation sequence for reuse. Thank you for your cooperation!
