This booster allows fast control, even with high flowrates

Thanks to its precisely manufactured bypass restriction, the new Type 3755 Booster (photo) can be adjusted exactly and lead-sealed in this setup. Because the Booster is completely pressure balanced, it provides a stable output, even under changing pressure conditions. The signal pressure is transmitted with defined hysteresis, without loss and emitting little noise. The Booster is designed so that the functional parts only come into contact with instrument air. Its exhaust-air port can be protected against weather or environmental influence, or the exhaust air can be routed through a pipeline. When combined with a positioner, the booster allows control valves with large pneumatic actuators to be controlled quickly and precisely, even with high flowrates or pressure drops. — Samson AG, Frankfurt, Germany
