Safety information, installation and maintenance For full details see the Installation and Maintenance Instructions (IM-S12-10) supplied with the product. Installation note: Caution - To protect the actuator diaphragm on steam applications a WS4 series water seal pot must be installed in the upstream pressure signal line to the actuator. Refer to TI-S12-03 for details. The valve should be mounted vertically downwards in a horizontal pipeline with the direction of flow as indicated by the arrow on the valve body. For applications with downstream temperatures below 125 °C the valve can alternatively be mounted vertically upwards.
