Safety information, installation and maintenance

For full details see the Installation and Maintenance Instructions (IM-S12-04)

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 downstream 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 DRV4B3 direct acting pressure reducing

valve flanged PN40.

Note: Add suffix 'N' if the Nitrile rubber diaphragm is required. i.e. DRV4B3N.
