STRATE EVA Relief valve

Area of use

Positive displacement blowers and single-stage screw compressors start up directly or following a star delta circuit if no gentle start or no frequency converter control are available. The unit is subjected to heavy mechanical load and requires high start-up current. For this reason, counterpressure must be reduced during the start-up phase; this is achieved by blowing off the increasing volume flow. The fully automatic medium-controlled STRATE relief valve EVA has been specially designed for this procedure. As well as not requiring any maintenance, the STRATE relief valve EVA is an extremely economical device for reducing load during start-up since there is no longer any need to use complex externally controlled valves or electronic start-up aids.
