Balance Pressure
The double-acting relay is designed to deliver pressure on both sides of a piston type actuator,
so that the cylinder can provide the required thrust and stiffness. This stiffness is factory
adjusted to 70% of the supply pressure. This means that, without any unbalance forces from
the valve stem, both outputs deliver roughly 70% of air supply pressure.
Although it is not recommended, the stiffness can be adjusted by moving the Adjustable Seat
assembly up or down.
