How does the MPR02 work?

The valve opens when the internal tank pressure exceeds the set value, releasing the excess and protecting the tank from overpressure damage. No external power is required.

What sizes and connections does the MPR02 offer?

Sizes are 1/2" ~ 4" (15A ~ 100A) with Flanged (RF, FM), Butt Weld and Thread connections.

What options are available?

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

VALVEPARK MPR02 Micro Pressure Relief Regulator

Model: MPR02

The MPR02 is a self-operated micro pressure relief regulator that automatically releases excess pressure inside a tank without external power. The valve opens when the tank pressure exceeds the set value, protecting the tank from overpressure damage. Sizes run from 1/2" to 4" (15A ~ 100A).

Features

Self-Operated Micro Pressure Relief: Automatically releases excess pressure inside the tank without external power. The valve opens when tank pressure rises above the set value, preventing overpressure and protecting the tank system.
Suitable for Tank Blanketing Applications: Designed for tank blanketing; it releases internal pressure when needed to keep the pressure of the storage tank safe.
Overpressure Protection for Storage Tanks: Prevents tank damage caused by excessive pressure. The valve opens at the set pressure, giving the tank protection system stable pressure relief performance.
