Safety information, installation and maintenance

For full details see 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 upstream temperatures below 125°C the valve can alternatively be mounted vertically upwards.

How to order

Example: 1 off Spirax Sarco DN40 DEP7B3 direct acting pressure reducing valve having flanged PN25 connections.

Note: Add suffix 'N' if the Nitrile rubber diaphragm is required. i.e. DEP7B3N.
