A new design of booster is available
from valve specialist Samson
Controls.

Due to its bypass restriction, the
booster can be adjusted exactly and
lead-sealed in this set-up.

As the booster is completely
pressure balanced, it is said to
provide 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. Only
the booster’s functional parts come
into contact with instrument air,
alternatively the boosters 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 pneumatic actuators to
be controlled, even in applications
with high flow rates or significant
pressure drops.
