V-exact II
Thermostatic valve body with stepless precision presetting
V-exact II thermostatic valve bodies are used in two-pipe warm water pump heating systems with normal to high temperature spread. The integrated stepless precision presetting makes precise hydraulic balancing possible with the aim of providing all heat consumers with hot water according to their heat requirements. The valve has a large flow range and is characterized by an optimized noise performance and very low flow tolerances.
Features & Benefits
Optimised noise behaviour
Through specially designed setting
High flow range
For various applications
Double O-ring seal
For durable and maintenance free operation
Valve body in gunmetal
Corrosion-resistant and safe

White protection cap.
Standards:
V-exact II valves meet the following requirements:
– KEYMARK certified and tested to DIN EN 215, series D.
– the “highly expanded version” and the “standard version” of the specification FW 507 drawn up by the Arbeitsgemeinschaft Fernwärme (AGFW) (Working Group for District Heating).
Pipe connection:
The female-threaded version is designed for connection to threaded pipe, or in conjunction with compression fittings, to copper precision steel or multi-layer pipe (only DN 15).
The male-threaded version, in conjunction with the appropriate compression fittings, permits connection to plastic pipe.
Versions with Viega press connection (15 mm) with SC-Contur are suitable for copper, Viega Sanpress stainless-steel, and Prestabo steel pipe.
