Eliminating the time-consuming trial and error procedures associated with fine tuning of control valves is possible thanks to a new design of valve booster available from valve specialists Samson Controls.
As a result of its precisely manufactured bypass restriction, the booster can be accurately adjusted and then lead-sealed in this set-up ensuring valuable time saved, whilst 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 only the boosterº£½Ç³Ô¹ÏÍø™s functional parts come into contact with instrument air, while the boosterº£½Ç³Ô¹ÏÍø™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.
