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.
