spindle: Niro-steel spindle with double O-ring sealing. The outer O-ring can be replaced under pressure. The body 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. Maximum working temperature: 120°C, with protection cap or actuator 100°C, with press connection 110°C. Minimum working temperature: -10°C.
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.
