The 42 series valve is a pilot operated piston valve ideal for controlling product flow in a desired direction. Pilot operated valves require a differential pressure for proper operation. Because of their design, it is not recommended that the pilot operated valves be used in suction systems.
Operating conditions for this valve are dependent on the compatibility of the intended product to the body and seal materials. The valve must be mounted on a horizontal line with the coil upright for proper operation. It is also recommended that 140 micron filtration be installed ahead of the valve to increase life expectancy and reduce maintenance.
