STRATE EVA Relief valve
Description
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. Product features Fully automatic control Specialized material G-AISi9Cu3 - specific to the requirements With solenoid valve for different motor speeds With overpressure valve For higher pressures and temperatures

The STRATE AWAaerob 110 - 1700 ventilation system consists of an oil-free compressor with noise suppressor, a switching system with operating hours counter and a timer, as well as a complete connection fittings set with manometer, check valve and connection line. The ventilation quantity and duration are adjusted by the timer based on the compressor run time. Fine pearls of oxygen are injected from the air. Ideal for short pressure pipes and high flow speeds in the pressure pipe Area of application for pressure pipes <= DN 200 Use with or without accompanying pipe (depending on the high and low points in the pressure pipe)

The BEV-G is a single-stage valve offering only the function of the first ventilation stage (coarse ventilation) provided by the two-stage valve (BEV-GF). It is not necessary to coordinate the valve to the working pressure in the first ventilation stage, since coarse ventilation is always closed under pressure. Type G (coarse ventilation): The air escapes through this valve until the medium closes it as it continues to flow. The valve remains closed under operating pressure. Ventilation of individual sections in sloped pressure lines, especially as a low pressure safety feature Quick ventilation of high points if fine ventilation is not required (short pump run times)

The BEV-F is a single-stage valve offering only the function of the second ventilation stage (fine ventilation) provided by the two-stage valve (BEV-GF). For ventilation quantities of 20 to 40 m3/h. Specific applications include high points which are under hydrostatic pressure even when the pump is shut down due to the height variation involved, and where no coarse ventilation is required, as well as at high points with low flow quantities. Type F (fine ventilation): Air escapes through this valve, and collected gases cause it to open once again, including under operating pressure, until the medium continues to flow and close the valve again. Installed at high points which are under hydrostatic pressure even when the pump is shut down due to the height variation involved, and where no coarse ventilation is required. Installed at high points of pressure lines with low flow quantities.
