Note:

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.

How to order

Example: 1 off Spirax Sarco DN40 DEP4B3 direct acting excess pressure valve having flanged PN40 connections.

Note: Add suffix 'N' if the Nitrile rubber diaphragm is required. i.e. DEP4B3N.
