New booster ensures fast, precise valve control

With the benefit of its precisely manufactured bypass restriction, the booster can be accurately adjusted and then lead-sealed in this set-up, saving time and minimising potential start-up problems.

As the booster is completely pressure balanced it provides a stable output, even under fluctuating pressure conditions. The signal pressure is transmitted with a defined hysteresis, without loss (gain 1:1) and emits minimal noise.

Another important benefit is that only the booster’s functional parts come into contact with instrument air, while the booster’s exhaust air port can be protected from the weather or other environmental factors.

When used in combination with a positioner, the booster allows control valves with large pneumatic actuators to be controlled quickly and precisely, even in applications with high flow rates or significant pressure drops.
