The MMV280 40,000 psi Multi-Mode Valve is a combination air-actuated high-pressure control valve and air preparation unit. The Multi-Mode Valve controls the flow of the filtered and lubricated air and high-pressure water to the gun or other appropriate device. It can be operated in FOUR different configurations (see operation options on the next page), including the use of multiple guns when configured for constant pressure or shut-off mode. This Multi-Mode utilizes a self-contained dual-seat cartridge that can be easily removed in a single piece and replaced in the field. Complete overhaul and modification can be accomplished in about one minute.
Rated for 40,000 psi (2,758 bar) maximum operating pressure, the control valve features connections specifically designed to resist wear and leakage common with high-pressure connections. Adapters are included to connect high-pressure hoses featuring the Type “M” connection. High-pressure adapters are also available
Features
Self-contained one-piece cartridge for easy removal, as opposed to multiple pieces for competitor type Systems
Cartridge and other pressure-containing components machined from hardened stainless steel and coated for longer wear life
The cartridge is hydraulically biased for safer operation, as opposed to a spring return system, which is susceptible to corrosion, wea,r and failure
Air supply pressure is regulated to the custom-designed actuation cylinder. This constant pressure eliminates damage to the valve caused by excessive activation forces
Regulator, filter, and oiler components are protected against abuse and damage
Ergonomically designed for ease of use and transportation
Heavy-duty, lightweight aluminum frame (3/8" plate)

| Model | Fitting | Max pressure | Max flow rate | Weight | Dimensions | Air requirement |

Dump Mode Configured for SINGLE gun operations. When the user is not blasting, the supply water is dumped to atmospheric pressure through the Multi-Mode valve discharge port. |

|
Constant Pressure Mode Configured for MULTIPLE gun operation. When the user is not blasting, pressure is maintained throughout the system by means of a nozzle (specifically sized for each operator’s flow rate) that is placed in the multi model valve discharge orifice. Multiple guns can be used without significant pressure fluctuation when other guns are not blasting. |

Dry Shut-Off Mode Configured for use with Intensifier type pumps and for SINGLE or MULTIPLE gun operation.Aplug is placed in the discharge orifice, preventing any water from venting through the Multi-Mode Valve. Actuation of the gun almost immediately produces desired blast pressures and flow rates. |
