The PRV 800 Differential Pressure Valve is a regulated valve designed to maintain and control differential pressure between different compartments of a protected ventilation system. It can be used for pressure regulation between separate spaces, including airlocks and the shelter interior relative to the outside environment.

The valve provides regulated airflow within the specified operating range and is intended for integration into ventilation systems where controlled differential pressure is required.

Differential Pressure Regulation

Maintaining a controlled pressure difference between connected compartments is an important part of protected ventilation-system design. The PRV 800 allows the differential pressure to be regulated between different areas of a facility.

The valve can be used to regulate pressure relationships between:

different compartments;
airlocks;
the shelter and the outside environment.

This makes the PRV 800 a dedicated component for ventilation and air-filtration systems requiring controlled airflow and differential-pressure regulation.

Main Specifications

According to the product information, the PRV 800 has the following specifications:

Regulated airflow: 50–800 m³/h
Mechanical shock resistance: >12 g
Standard flange: 8 Inch

These are the specified technical parameters of the PRV 800.

Regulated Airflow: 50–800 m³/h

The regulated airflow range is 50–800 m³/h.

This parameter defines the airflow range specified for the valve and is important when integrating the PRV 800 into a ventilation system. The required airflow should be considered when selecting and configuring the associated ventilation equipment.

Mechanical Shock Resistance

The PRV 800 has a specified mechanical shock resistance of >12 g.

This characteristic describes the mechanical shock-resistance parameter provided for the valve and is particularly relevant when equipment is selected for protected infrastructure.

Standard 8-Inch Flange

The PRV 800 uses a standard 8 Inch flange.

The flange specification is an important installation parameter because it determines compatibility with the corresponding ventilation-system connection. When planning installation, the connection dimensions of the associated ductwork and equipment should be checked against the specified flange.

PRV 800 in Shelter Ventilation Systems

Differential-pressure regulation is an important element of controlled ventilation in protected spaces. The PRV 800 provides a dedicated means of regulating airflow and maintaining the required pressure relationship between connected areas.

Its specified combination of 50–800 m³/h regulated airflow, >12 g mechanical shock resistance, and an 8 Inch standard flange provides the key technical information needed when evaluating the valve for a particular ventilation-system configuration.
