With particularly low resistance
Thermostatic valve body without presetting
The thermostatic valve bodies with particularly low resistance are used e. g. in two-pipe low temperature heating systems with a small temperature spread and conventional one-pipe heating systems.
Features & Benefits
Double O-ring seal
For durable and maintenance free operation
Valve body in gunmetal
Corrosion-resistant and safe
Thermostatic insert replaceable under pressure
with DN 10 and DN 15

Standards:
The thermostatic valve bodies meet the following requirements:
– KEYMARK certified and tested according to DIN EN 215.
For KEYMARK certified thermostatic heads and thermostatic valve bodies, see also datasheet 'Thermostatic Heads'.
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.
