Providing accurate and reliable valve position monitoring, the APL-series limit switch boxes are designed for quarter-turn valve applications (0 to 909) used in many industries: Chemical & petrochemical, Municipal wastewater, Power plant, Oil refinery, Marine, General industry, A wide range of product with many switch and other accessory options cover various customer needs: cost-effective, corrosive/ hostile environments, enclosure standards(IP67, IP68, NEMA 4, 4X, 6, flame-proof, intrinsic safety), higher/ lower operating temperature, multiple cable entries,3-way or 5-way valve applications, current position signal-ling, solenoid valve, and many more. The housings of the standard APL series are die-cast aluminum. To provide high corrosion resistance, they are chromate coated and a polyester powder coating is further applied. The housing of APL-5 is available in either aluminum die-cast,316 stainless steel, or 316L stainless steel. Limit switches can be widely used in the three-coordinate control and limit of lifting and transmission machinery in construction, port, mining, and other industries
