Prospector poppet valve has been expanded to operate in extremely low temperatures, from –40°C (–40°F) to 60°C (140°F). Its high flow and short stroke result in fast response times. It is available in air pilot or solenoid pilot design in a wide range of voltages. It is rated at flow coefficients from 1.2 to 49.5 Cv and certified to meet rail industry requirements for extreme temperatures, shock, and vibration. It also stands up to other harsh environments, such as metal forging, pressing, stamping and roll-forming, making it well suited for machine tools and conveyor systems in pulp and paper operations and food and beverage processing.
