The lever-operated pressure regulator in the M3400 series is designed to allow rapid changes in pressure settings, both at test panels and control stations. The high quality unit is capable of handling high flows and exhausts, combining positive control with good sensitivity. The model 3400 also features a combination of the model 1000 high flow pressure regulator and a hand-held operated layer mechanism, with a maximum travel of 120 degrees. The model 3400 is delivered in four different pressure ranges, recommended for use in systems that require the execution of hand-operated pressure controls, such as throttle control in an engine room or engine. The regulator is also a logical choice for rapid control in various applications, including construction machinery and various equipment.
