Remote Actuator Vent Gas Connection

Remote Gas Piping

Remote vent gas piping must be free flowing to minimize pressure buildup during actuator
venting. Pressure buildup inside the vent gas piping can affect performance of the control
valve actuation. (Excessive pressure buildup can significantly affect the performance).
Pressure buildup inside the vent gas piping can be minimized by keeping the overall vent gas
piping length as short as possible while limiting the number of fittings, elbows, and short
radius turns. Keep the vent gas piping diameter large with a minimum (tubing) diameter of
12.7 mm (1/2") for SVI II ESD Single Acting.
In addition to remote vent gas piping, ensure that all components and covers are correctly
installed.
