Purpose :

Pilot valve ТУ У 29.1-33704680-014:2011 are used to automatically protect of equipment and pipelines as a part of pilot-relief device from unallowable pressurizing by the way of operation medium excess discharge

Drive type - solenoid valve (ЭМ), servodrive (Сп), lever (Рч).

Connection to pipeline – by welding (pic. 1, 2, 3) and flanged (pic. 4).

Installation position – vertical.

Ambient class – У3 according to GOST 15150-69.

← impulse supply to relief valve.
