A remote control valve is a typically closed, self-sealing, fail-safe valve. The significant internal air path completely eliminates the pressure loss of other remote control systems.
A remote control valve controls the blasting process in a sand blasting machine.
When a sand blasting machine has a remote control system, the operator is easily turning the unit on or off.
It also makes the operator's security better. For air venting, an exhaust valve is incorporated into the top of the remote control body. The air intake and exhaust operations are both controlled by a single valve.
The Remote Control Valve is used by an abrasive blasting operator for starting up and shutting down the Sandblasting machine. The remote control system comprises a remote control valve an DMS (dead man switch), which are joined by a twin-pipe.
The control handle often referred to as a dead man switch, is the trigger for the Remote Control Valve System. When the operator releases the Remote control handle, the Sand Blasting machines deactivates, stopping air and abrasive flow through the sand BlastingNozzle.
The Remote Controls operate pneumatically. If the operator is not pressing the dead man handle, one stream of air travels down the outbound side of the twin line and escapes through an opening located under the lever. The usually closed inlet valve remains closed, and the usually open outlet valve remains open.
When the dead man handle lever is pressed, the opening is sealed, and air in the outbound line returns through the inbound line to open the inlet valve and close the outlet valve. This action pressurizes the Sand blasting machine and begins the Sand Blasting process. Freeing the handle puts the machine in exhaust mode, which closes the inlet valve, and opens the outlet valve to depressurize the Sand Blasting machine and stop the blasting.
Pneumatic remote controls work great in blasting operations with blast pipe lengths less than 100 ft.
