Manualy Controled Valves are hydraulic control valves which are operated by line pressure and provide 3-way mini valves for on-off operation. The valve has a minimum opening pressure of 0.7 bar. Thanks to its flexible diaphragm, it performs an easy and quick check operation in high pressure applications and is shut off without impact.

Automatic control valves are used to perform the required operations as hydraulic with line pressure without the need for energy sources in the network line.
Valve Closing Mode
When the water pressure reaches the diaphragm, the water creates hydraulic force. This hydraulic force diaphragm, combined with the force applied by the spring creates a complete seal and allows it to close.
Valve Opening Mode
When the pilot on the main control valve in the closed position is placed in the evacuation position, pressurized water on the diaphragm of the main control valve is discharged. When the line pressure reaches the position to overcome the spring force, it applies hydraulic force from the bottom to the diaphragm of the control valve and allows the valve to reach the full open position
Modulation Mode
They are pilots connected to the control valve which enables the main valve to operate in this position. According to the amount of flow and pressure required to be adjusted, it controls the water pressure on the diaphragm continuously and allows it to operate in modulated position.

Installation
- The connection to the closed “C” outlet of 3-way valve is provided with the help of copper or plastic pipe after connection to the valve Inlet, finger filter number 3 and mini ball valve number 2.
- Valve rated diameter should be the same or a small rated diameter as the line diameter.
- In the direction of the arrow indicated on the valve Mount.
- Isolation valves (butterfly or sliding valve etc.) in the line Assembly of the valve.B) it is recommended to use air discharge valve, quick pressure discharge control valve (QR) and dirt retaining valves.
- Cavitation risk during pressure drop is dangerous for valve body. Adjust the output pressure value you want to adjust by looking at the cavitation chart or contact our company.
Adjusting
- Select the setting position with 3-way selector valve indicated by “1” on the valve.
- Valve in open position is open “close” position Valve is closed

- Finger Filter
- Blind plug
