Booster simplifies fine-tuning of control valves

Samson Controls (London) Ltdvisit website

 

Samson Controls is introducing a new design of booster that eliminates the time-consuming trial-and-error procedures often required for fine-tuning control valves. Thanks to its precisely manufactured bypass restriction, the booster can be adjusted exactly and lead-sealed in this set-up, which results in valuable time saved while also 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 the booster's functional parts come into contact with instrument air only; alternatively 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.
