The DOROT DAV-M-SA valves were designed allow air flow into the pipe when it is draining, preventing the risk of excessive negative pressure that may cause collapse of the pipe.
The valves will also enable drain of small quantities of air- which tend to accumulate in the elevated locations during normal system operation, reducing the effective cross-section of the pipe, thus damage the hydraulic performance of the network.
The outflow of the air is restricted, so in the case of fast filling-up of the pipe by water, which forces the air out- it a not escape at the same rate as the water flow, consequently a "temporary air cushion" is created, absorbing the kinetic energy of the approaching water mass. The flow of the air is adjustable by the user.
All the valve components are included within a sturdy, tamper-proof body.
