The Dungs 228-222 (DMV-D 703/602) Dual Modular Valve consists of two automatic normally closed shutoff valves. The Valve 1 is fast opening and closing, while the Valve 2 is fast opening. The unit has an electrical rating of 24 VAC at 50-60 Hz.
The Dungs Dual Modular Valve (DMV) comprises two automatic shutoff valves enclosed in one compact housing. The valves can be wired in two ways, in parallel or individually. Applicable gases are dry natural gas, propane, butane, air, and inert gases. Series DMV-D…/602 operates normally closed, both valves are fast opening & closing, and V2 has adjustable maximum flow.
The DMV is a perfect choice for industrial and commercial heating that uses two safety shutoff valves. Designed in a way that the valve optimizes flow and provides a low-pressure drop.
