Convert an existing pot to a fast response remote control system. The Thompson Metering Valve operates on the pressure hold principle, i.e the pot remains pressurized once the deadman handle is released. Depressurizing the pot requires manually opening a blow down valve. This system is ideal for stop/start blasting, i.e spot-blasting and difficult access jobs. Also the only type of remote control system that works on multi-outlet blast machines. See us for deadman system spare parts. Also available, a wide range of alternate deadman systems.
