REMOTE CONTROL SYSTEM FOR BLAST VESSELS

The RCV remote control valve is used for controlling the compressed air feed to the machine while simultaneously controlling air blow-out from the machine. Both control functions run concurrently when the DMH handle is pressed or released by the abrasive blasting operator. Air is bled from the tank via a damper, which is included in the delivery set.

The DMH remote control handle
is fastened to the nozzle and connected
to the RCV remote control valve
using a dual hose.

Design features

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.

APPLICATION

Abrasive blast cleaning, paint spraying with a pneuamtic drive, guniting, and construction and road works using pneumatic tools.

DESIGNED FOR OPERATION

With any brand of portable and stationary screw compressor unit. Compressed air flowing from a diesel compressor has a high temperature of approximately 90°C. At such a temperature, compressed air contains a large amount of moisture in the form of steam vapour. If an aftercooler and cyclone condensate separator are not used, compressed air can add up to 21.5 litres of water per hour into the system with a compressor operating at 5.7 m3/min capacity and a pressure of 7 bar. Moisture extraction systems MEX cool compressed air to a temperature 3° C – 10° C higher than the ambient temperature. Once the air is cooled, vapour moisture condenses and up to 95% of condensed moisture may be eliminated from the system.
