ALL YOU WANT TO KNOW ABOUT PRESSURE WASHERS
OPEN SYSTEMS
| There are many applications for
a pressure washer that require no unloader valve or trigger gun.
These systems are generally turned on and off automatically or by an
operator or a solenoid valve.
An automatic car wash is a good example of an open system. The water is pumped through a multi-nozzle setup. The system turns the pump on and off when needed. These is no need for a shutoff or unloader valve. Most of these systems would include a high pressure relief valve for safety purposes and ball valves the shut flow off for maintenance. |
