A remote control valve for sand blasting is a type of valve used to control the flow of abrasive media in a sand blasting machine system. Sand blasting is a process used to clean or prepare surfaces by forcibly propelling a stream of abrasive material against them. The remote control valve allows the operator to control the flow of the abrasive material from a safe distance, without having to manually operate the valve at the sandblasting nozzle.
Typically, a remote control valve for sand blasting will be a pneumatic valve that is controlled by compressed air. The valve is typically mounted on the sand blasting pot, which is the container that holds the abrasive media. The remote control device can be a handheld pneumatic control switch, or it may be integrated into a more advanced sand blasting control system.
Remote control valves for sand blasting are essential for ensuring the safety of the operator and for providing precise control over the abrasive media flow rate. The operator can adjust the flow rate of the abrasive material to achieve the desired cleaning or preparation effect on the surface being treated.
Types of Remote Control Valve
RCV Remote Control Valve
The RCV remote control valve is used to control the compressed air feed to the machine as well as the air blow-out from the machine. When the abrasive blasting machine operator presses or releases the DMH handle, both control functions are activated. A damper incorporated in the delivery set is used to bleed air from the tank.
DMH Remote Control Valve
The DMH remote control handle is fastened to the sand blasting nozzle and connected to the RCV remote control valve using a dual hose.
The RCV remote control valve responds when the DMH handle is pressed. The blast machine's tank is pressurized and the abrasive blast cleaning process begins. When the DMH handle is released, the RCV remote control valve closes, the abrasive blast cleaning process terminates and the machine's tank depressurizes.
