Cast Steel Pressure Reducing Valves.

Model DRV4 and DRV4G,  DRV7 and DRV7G

The DRV4 is a cast steel direct acting bellows sealed pressure reducing valve. The standard version has an EPDM diaphragm and is suitable for steam, water and air applications. The DRV4 is available with a Nitrile rubber diaphragm (suffix 'N') for oil applications. A Nitrile rubber soft seated version (suffix 'G', limited to 90 °C) is also available for applications that require tight shut-off. It is recommended that for these applications, a maximum pressure turndown ratio of 10:1 is observed. Note: To protect the actuator diaphragm on steam applications a WS4 water seal pot must be installed in the downstream pressure signal line to the actuator. Refer to TI-S12-03 for details.
