Membrane two- and three- way
regulation valves – line 515
line
Use - in regulation circuits of heating, air-conditioning and waterworks systems for
accurate flowage regulation of non-aggressive liquids, gases, and fumes up to a
temperature of 200°C. The piping is clean, free of pressure impacts.
Design - two-way or three-way
– two-way
a) direct function – D
the higher the entry signal is, the lower the flowage via the valve is
b) restoring function – R
the higher the entry signal is, the higher the flowage via the valve is
– three-way
a) mixing function – Y
the higher the entry signal is, the flowage either decreases or increases at the
same time
