The job of the slow-start valve is to gradually pressurize the pneumatic system upon switching it on. The gradual pressurization takes place until about 60% of the supply pressure is reached. The pressurization time can be adjusted through the speed controller positioned in the upper part of the body. Application: it can be singularly used, or, more commonly, assembled with the shut-off valve. The AVP avoids any dangerous pressure surge, that may be caused by quickly supplying the system to the working pressure.
