GD-45 Direct-Acting Pressure-Reducing Valves


For steam, air and non-corrosive gases

The GD-45 is a compact, high-performance direct-acting valve. Inexpensive to buy and use, it is ideal for those moderate-flow applications that do not justify the higher cost of pilot-controlled valves. The GD-45 is well suited for laundry and dry-cleaning equipment, hospital equipment, tire molds, humidifiers, small heaters and applications in food processing.
