AV2000-N02-AC110 Supply Pressure: 29 to 124 PSI (0.2-0.86 MPa) Includes two 1/8" NPT gauge port plugs **Pressure Gauge not included can be purchased through MettleAir (GSR-150-BK) FUNCTION: Soft Start Valves are designed to gradually increase the supply pressure during system start up to prevent cylinders/tools from slamming open/shut due to air being introduced to the system too quickly. The soft start up valve is designed to allow a soft start up to 50% of the regulated pressure, and then the remaining pressure is allowed to flow through unrestricted. For example if the regulated pressure is 100 PSI, and we have the soft start valve installed at the point of supply. The soft start valve will allow the first 50 PSI to fill up gradually in the system, once the system pressure reaches 50 PSI, the valve opens fully to allow the remaining pressure build up to 100 PSI quickly. The start up speed / rate is adjustable by the brass set screw at the bottom, turning it clockwise will create a slower pressurization rate, turning it counter-clockwise will create a faster pressurization rate. Once the valve is turned off, the air from downstream is directed towards the exhaust port, however the use of the exhaust port is optional, if you wish to maintain a closed system you may elect to plug the R exhaust port.
