New booster ensures fast, precise valve control
22 June 2014
The time-consuming trial and error procedures associated with fine tuning of control valves is now a thing of the past, thanks to a new design of valve booster from Samson Controls.
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.
