All rights reserved.Remote Actuator Vent Gas ConnectionRemote Gas PipingRemote vent gas piping must be free flowing to minimize pressure buildup during actuatorventing. Pressure buildup inside the vent gas piping can affect performance of the controlvalve actuation. (Excessive pressure buildup can significantly affect the performance).Pressure buildup inside the vent gas piping can be minimized by keeping the overall vent gaspiping length as short as possible while limiting the number of fittings, elbows, and shortradius turns. Keep the vent gas piping diameter large with a minimum (tubing) diameter of12.7 mm (1/2") for SVI II ESD Single Acting.In addition to remote vent gas piping, ensure that all components and covers are correctlyinstalled.Single Acting InstallationTools required:Figure 79 Step 1 Remove the Exhaust Cover 9/16 and 1" wrenches M3 and M5 Hex KeyUse an M3 hex key to remove the exhaust cover.Use a 9/16 wrench to install a 1/2"X1/4" fittinginto the exhaust port.
