Air & Vacuum Air Valve AV10


The AV-010 Air & Vacuum Valve discharges air at high flow rates during the filling of the system and admits air at high flow rates during drainage , pump shut-off or at water column separation.


Agricultural and landscape irrigation laterals.


The air & vacuum valve discharges air at high flow rates during the filling of the system and admits air at high flow rates during drainage, pump shut-off or at water column separation.

High velocity air will not blow the float shut. Water entry will lift the float which seals the valve.

The smooth discharge of air reduces pressure surges and other destructive phenomena.

At any time during system operation, should internal pressure of the system fall below atmospheric pressure, air will enter the system.

The intake of air in response to negative pressure protects the system from destructive vacuum conditions and prevents damage caused

by water column separation. Air entry is essential to efficiently drain the system.

As the system starts to fill, the valve functions according to the following stages:

  1. Entrapped air is released by the valve.
  2. Water enters the valve, lifting the float and sealing the valve.

When internal pressure falls below atmospheric pressure (negative pressure):

The float will immediately drop down, opening the air & vacuum orifice.

Air will enter the system.

Yamit Hydraulic Auto Screen Filter Series 200

AF-200 Automatic Hydraulic Suction Scanner Filters

ApplicationsCompact low flow screen filters with automatic suction scanner  back flushing for standard industrial and municipal applications. Very popular in the irrigation sector.

Standard Characteristics:

  • Filter element: – Stainless Steel screen AISI 316, supported by a PVC cylinder.
  • Available filtration grades: 80 – 3000 microns
  • Filter housing material of construction: Carbon Steel ST37.2
  • Pre-treatment: sand blasting up to Sa 2.5 grade
  • Exterior & Interior coating: electrostatic oven baked polyester-epoxy powder coating with a thickness of 150-200 micron
  • Connections: Victaulic, Threaded socket and Flange
  • Maximum recommended working pressure: up to 10 bar (145 psi).
  • Minimum operating working pressure during flushing: 2 bar (28.4 psi)
  • Equipped with an electronic control system (6V DC, 12 V DC, 24V AC)


Cleaning of the screen is performed automatically once the pressure loss (ΔP) across the filter has reached the preset value up to 0.5 bar (7psi). The flushing valve opens, pressure is released from the hydraulic piston, and debris-laden water is discharged through the flushing valve. Pressure in the hydraulic motor chamber and the dirt collector is significantly lowered causing the dirt collector nozzles move along and rotate cleanings the whole internal screen surface. The flushing cycle takes 5 seconds. The flushing valve closes at the end of the cycle, pressure reapplied to the piston, moving the nozzles back to their rest position, and the filter is cleaned. During the whole process water supply is uninterrupted.
