Float Level Control Valve

Hydraulic Control Valves

Flatörlü Seviye Kontrol Vanası, su depolarındaki seviyesini sürekli kontrol eden hidrolik kontrol vanasıdır.

Ana vana kontrolü 2 yollu flatör ile manuel olarak sağlanır. Depo girişlerine monte edilen ana vana, su seviyesi maksimum seviyeye ulaştığında darbe yaratmadan kapanır. Su seviyesi minimum seviyeye düştüğünde ise ana vana kendini açarak deponun dolu kalmasını sağlar. Vana açma-kapama hızını ılmıştır. Vana sisteme yatay veya dikey monte edilerek çalıştırılabilir. Kumanda sistemi olarak elektrik flatörlü ve diferansiyel flatör tip kullanılmaktadır.

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.

  • Easy operation and maintenance with simple structure
  • Low cost
  • Working at wide pressure value range
  • Perfect modulation even at low flow rates
  • Continuous on / off with flexible aperture
  • Full seal with reinforced diaphragm and inner spring
  • Long life with epoxy-polyester coating
  • Wide range of control area with the use of different pilot valves
  • Ability to work in horizontal and vertical positions in application areas

Installation
  • After connecting the 3 number finger filter and 2 number mini ball valve to the valve inlet, it is connected to the needle valve and valve cover numbered “1” with the help of copper or plastic pipe.
  • One outlet of mini ball valve “2/1” is connected to the pilot inlet with flattened end to the valve cover.
  • Valve outlet” 5 ” is connected to the blind.
  • 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
  • Fixed flat pilot valve indicated by “4” according to water level in reservoir or reservoir Mount.
  • Connect one end of the hydraulic pressure signal pipe supplied with Valve to the spherical valve shown in “2/1”, and the other end to the flattened pilot valve.
  • Open spherical valves shown with “2” and “2/1”.
  • Adjust the opening and closing speed of the main valve with needle valve shown with “1”.
