The correct positioning of making impulse in the pipeline is essential for the proper functioning of the throttle valve,
therefore install the pilot impulse outlet regulator downstream at a minimum distance of 5 times the nominal pipe
diameter and stretch obstruction-free pipe with a pipe diameter where the gas flow rate does not exceed the maximum
speed of 25 m / s (considering the lower output pressure and the maximum flow).
To obtain a better pneumatic signal, use ½ OF tubbings "stainless steel AISI 316 to connect the regulator to the
process.
In order to avoid the accumulation of impurities and condensate in the impulse taken recommend that they be
installed with a slope of 5% to 10% towards the connector on the pipe.
Pay attention to the connections welded pipe for it to be totally clear, without any welding residue that could
interfere with pneumatic signal.
Each throttle model HORUS SC (FF) needs three process connections: one directly to the actuator on the
diaphragm, one that will be connected directly below the pilot and a third for the purpose of discharging the actuator
under the diaphragm.
They should be installed block valves of any kind into the pressure
regulators pulse taken.
