V-exact II

IMI Heimeier
Compare
​​​​​​​ 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.

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

Technical description

Heating and cooling systems.

Function:

Control
Stepless presetting
Shut-off

Dimensions:

DN 10-20

Pressure class:

PN 10

Temperature:

Max. working temperature: 120°C, with protection cap or actuator 100°C, with press connection 110°C.
Min. working temperature: -10°C.

Materials:

Valve body: Corrosion resistant Gunmetal.

Marking:

THE, country code, flow direction arrow, DN and KEYMARK-Designation. II+ - Designation.
White protection cap.

Standards:

V-exact II valves meet the following requirements:
– KEYMARK certified and tested to DIN EN 215.
– 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.

Connection to thermostatic head and actuator:
