Direct Acting Pressure Reducing Valve

Authentic and long-term operation of SWAS depends upon the efficiency of sample conditioning components for which accurate pressure and flow control is most essential.

Main application of this product is chemical analysis of water and steam samples in modern Power Generation Plants.

Axis offers very reliable product for system designer where high pressure reduction with flow control is a major challenge.

The flexible needle-in-chamber type design permits for adjustable pressure drop and flow control including ease of cleanliness. Both of these features provide long life of sample conditioning parts.

This reducer is specially designed for high pressure sample persisting above 35 bar and up to 350 bar. It develops fixed pressure drop and its adjustable using a knob on top.

The APRV1 consists of two needles joined to a large chamber. This assembly provides precise insertion. The high pressure steam enters into APRV1, flow passes through one needle then turns towards the other needle and then out.

Pressure drop is proportionate to set pressure and till what extent a needle is inserted inside a chamber.
