PRV DIFFERENTIAL PRESSURE VALVES
PRV - Differential Pressure Regulation Valves
PRV 800 valves are designed to maintain constant pressure in the rooms in which they are installed. They are used to regulate pressure between the rooms in protected space and are equipped with a knob which helps to perform the regulation on site. These valves are to be installed on the internal walls of the building and usually facing the higher pressure side but will also work if installed on the lower pressure side of the room.
Overview
-
Normally closed blast valves are installed on the exhaust side, allowing controlled air replacement and creating the desired internal air over-pressure level.
-
The valves are extremely durable and withstand heat and corrosion.
-
Normally open Blast valves can be equipped with a dust pre-filter for removing dust particles.
-
The valves are low in pressure drops and are maintenance free.
-
They are continuously and regularly tested by various International Standard Institutes.
