RIV980 Flow control with flappers or propeller Riels® Instruments

Product catalog summary

Overview: The document provides technical specifications and installation guidelines for RIV980 flow control devices, which are designed for monitoring the movement of liquids such as water, oils, gasoline, and diesel. These devices are available with integral flappers or propellers and are constructed from AISI 316L steel or carbon steel.

Specifications:

Materials: Body made of AISI 316L steel or carbon steel. Internal fan and support ring made of AISI304, with optional MOPLEN fan.
Glass Types: Double calcium-sodium tempered glass or DIN7080 borosilicate tempered glass.
Temperature Range: Calcium-sodium glass: -10°C to 160°C; Borosilicate glass: -10°C to 280°C (up to 300°C with MICA protection, which requires replacement after 300 hours of use).
Seals: Fasit® 400 seals, suitable for temperatures up to 400°C.

Installation Guidelines:

Ensure the valve is installed following the flow direction indicated by the arrow on the body.
Use a compatible material to seal the threads according to the fluid used.
Screw the valve onto the threaded tubes using the hexagonal parts for proper locking.
Support piping with heavy clamps to prevent stress on the valve.
Open upstream shutoff devices slowly to avoid water hammer.

Performance Data:

Pressure ratings vary with temperature, with maximum pressures of 40 bar at 37°C, decreasing to 20 bar at 300°C for certain models.
Dimensions and pressure ratings are provided for various sizes, ranging from 1/2" to 2".

Models:

RIV980 series with integral flappers.
RIV980V series with propeller, featuring slightly different pressure ratings.

For a correct mounting the valve must be installed following the flow direction indicated by the arrow engraved on the body Use to seal the threads of a material compatible with the fluid used. On order to mantain the watertight on the threads,a material compatible with the fluid must be used. Screw the valve on the threaded tubes by positioning the key exclusively on the special hexagonal parts up to the locking of the valve on the tube. After connecting the valve to the pipes, make sure the valve does not suffer stress due to piping, so use of heavy clamps to support the piping.
