​​​​​​​ 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.

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

Technical description
