Pressure Reducing Valve RP45 (ASME)

The ADCA RP45 series pressure reducing valves are single seated,
bellows sealed controllers that operate without auxiliary energy.
Designed for use with steam, compressed air, and other gases
compatible with the construction.
These valves are particularly suitable for reducing steam pressure in
all energy and process systems where pressures must be kept under
control.

 

OPTIONS:

 

Soft sealing in PTFE/GR for use with steam. Soft sealing in nitrile rubber for use with air and gases. Low-noise flow divider. Sensing pipe on body.

 

USE:

 

Steam, compressed air and other gases compatible with the construction. Limited use with liquids. Consult manufacturer before installing the valve with liquids

 

AVAILABLE MODELS:

 

RP45S and RP45ST or N – carbon steel. Suffix T: soft sealed with PTFE/GR. Suffix N: soft sealed with nitrile rubber.

 

SIZES:

 

1/2″ to 6″.

 

CONNECTIONS:

 

Flanged ASME B16.5 Class 150 or 300.

 

AVAILABLE ACTUATORS:

 

A1, A10, A11, A12, A3, A4, B1, B3, B4 and C11 – carbon steel. A2, A21, B2 and B21 – SG iron or carbon steel.

 

INSTALLATION:

 

Horizontal installation with the actuator vertically, pointing downwards. Installation with the actuator pointing upwards is possible only when the medium temperature is below 90 ºC. The sensing pipe, if not fitted on the valve body, must be installed downstream of the valve at a minimum of 1 meter away or 15 pipe diameters. In steam applications, a “Y” strainer, humidity separator and steam trap should be installed upstream of the valve.
