The popular Hodge Clemco RMS100 with 1.1/4″ port is fitted to all blast machines as standard. This valve allows the machine to be depressurised from a remote deadman handle fitted at the blasting nozzle position.

It incorporates two valves in one body, the lower valve for incoming compressed air and the upper valve for controlling the exhaust to the abrasive blast cleaning machine.

A constant source of compressed air is supplied to the inlet RM-23(R) on the deadman handle via a 1/4″ i.d flexible air hose (hose -7DR) from the fitting RM-23(R) on the lower part of the RMS-100 body.  The air supply is returned from the outlet RM-23(Y) on the deadman handle to the fitting RM-23(Y) on the upper part of the RMS-100 body by a second 1/4″ i.d. air hose (Hose-7DY).

Activation of the two valves is achieved simultaneously on closing the deadman handle.  Deactivation takes place immediately on release of the handle or by opening the safety petcock on the RMS-100 valve body.

It is a feature of this system that the air exhausted from the abrasive blast cleaning machine does not pass through the working parts of the valve, thus any wear caused by airborne particles of abrasive is restricted to the rubber diaphragm (RM-14).

The valve is designed for easy maintenance with the use of only a few tools. There is a maintenance video in the Videos section below.
