1.3.4.5 Clemco remote controls operate pneumatically on a return-air principle. A stream of control air travels from the orifice on the inlet valve, down the outbound twinline (shown shaded in Figure 2) and escapes through the opening located under the control handle lever. The normally-closed inlet valve remains closed, and the normally-open outlet valve remains open. As long as air escapes through the handle’s opening, the remote control system remains inactive. When the operator presses the control lever, a rubber button seals the opening, and outbound air returns through the inbound line...

prevent particles to pass without jamming. Finer abrasives are especially sensitive to moisture and requires very dry air to prevent bridging in the metering valve. 1.4.3 Sand: Sand should never be used because of the respiratory hazards associated with abrasives containing free silica. 1.4.4 Slag: Slag abrasives are compatible with the blast machine fitted with the MQV manual Quantum metering valve. Obtain safety data sheet (SDS) to identify hazardous substances. 1.4.5 Steel: Steel shot and steel grit may be used with machines fitted with the MQV manual Quantum metering valve. Shot applications...
