Membrane safety and start-up valves
Safety and start-up valves are primarily used to protect the blower units.
ΔP = 0 – 100 kPa
Volumetric flow rate
Type PMVD: Q = 15 – 22 000 m3/h
Type PRVD: Q = 200 – 22 000 m3/h
DN40 – 300
The PMVD safety valves are characterized by a small pressure differential over the entire range of specified flow rates of approx. 3 kPa, in comparison to simple straight spring valves.
The combined safety and start-up valves in the PRVD version are also equipped with a relief (start-up) function to help the blower unit (electric motor) start up.
Valves consist of a main (power) valve and a control (pilot) valve.
The main valve carries out the actual discharge of air from the system, the control valve senses the pressure of the insured air through a pulse pipe and controls the operation of the main valve by filling or draining it.
The mounting of the valve is most often done by the flange of the main valve.
KUBÍČEK valves are certified according to Government Regulation No. 219/2016 Coll. (Directive 2014/68/EU), Pressure Equipment, using the standards of ČSN EN ISO 4126-1:2014.
