Manifold Air Distributor Valve – Push/Pull with Air Reset/Lock-out

The Betts Manifold Air Distributor Valve can be used to control the operation of an Air Manifold system on a cargo tank.  Model AD22V is a push/pull 5/2 directional control valve that can be utilized as a single control valve or stacked to create a bank of valves used to control multiple compartments.  The two-position control valve provides hold-down air to the air manifold compartment valve when the knob is pushed in. When the knob is pulled out, it opens the air manifold compartment valve and provides air to lock-out the opposite bank’s corresponding distributor valve to reduce the chance of cross contamination.  The air reset feature retracts the distributor valve knob to the closed position when system shut down air is provided.

The Distributor Valve configuration is commonly used in conjunction with a Master Control Valve (see AD22MC) and this combination is offered as a “plug and play” Air Control Panel assembly (see AP22).  An Emergency Shutdown Valve (see ES22) is also offered to complete the pneumatic control system.

The valve blocks are lightweight anodized aluminum for corrosion resistance and performance.  All ports are ⅛” NPT and the valve body has ¼-20 mounting holes for front mounting or Ø.26 through holes for bottom mounting.
