Tayfur - Pressure Sustaining Control Valve
Pressure Sustaining Control Valve is a hydraulic control valve designed to protect the system by rapidly discharging the high pressure wave by sudden opening movement in water systems with excessive pressure increase. With the pilot on the valve, the input pressure is adjusted with the desired pressure. If for any reason the inlet pressure in the system rises above the set value, the valve is opened quickly to release the excess pressure to the outside and the system is protected. Despite its sudden opening, due to the hydraulic principle of operation, the closing of the valve is slowed down so as not to create a ripple. It provides a completely leak-tight seal. It can also be used as a safety and warning valve at the exit points of the pressure reducing control valves alone at critical points in the water system.

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.
