What is the MPR01 used for?

It is used in tank blanketing systems, especially nitrogen sealing systems of medium and large storage tanks. It keeps the tank pressure stable to protect the stored medium.

What is the lowest pressure it can control?

The minimum control pressure is 0.5 kPa, and the typical inlet pressure range is 2.0~8.0 bar(G).

What options are available?

NBR / FKM / EPDM diaphragm, and ANSI Class IV or ANSI Class VI seat leakage.

VALVEPARK MPR01 Micro Pressure Reducing Regulator

Model: MPR01

The MPR01 is a self-operated micro pressure reducing regulator that controls the outlet pressure automatically without external power. It is used for tank blanketing and nitrogen sealing systems and provides stable micro-pressure control from 0.5 kPa. Sizes run from 1/2" to 4" (15A ~ 100A).

Features

Self-Operated Micro Pressure Control: Controls the outlet pressure automatically without external power, keeping stable micro-pressure conditions in gas control systems with reliable, energy-saving operation.
Suitable for Tank Blanketing Applications: Designed for tank blanketing systems, especially micro-pressure gas control such as nitrogen sealing systems of medium and large storage tanks.
Reliable Tank Protection System: Can be combined with a breathing valve or nitrogen relief regulator to form a complete tank protection system. The minimum control pressure is 0.5 kPa, and the typical inlet pressure range is 2.0~8.0 bar(G).
