For durable and maintenance free operation
Corrosion-resistant and safe
with DN 10 to DN 20
Heating and cooling systems.
Max. working temperature: 120°C, with protection cap or actuator 100°C, with press connection 110°C. Min. working temperature: -10°C.
Valve body: corrosion resistant GunmetalO-rings: EPDM rubberValve disc: EPDM rubberReturn spring: Stainless steelValve insert: BrassThe complete thermostatic insert can be replaced using the fitting tool without draining the system.Spindle: Niro-steel spindle with double O-ring sealing. The outer O-ring can be replaced under pressure.
Valve body and fittings are nickel-plated.
THE, country code, flow direction arrow, DN and KEYMARK-Designation. II+ -Designation. Black protection cap. Black stuffing box.
The thermostatic valve bodies meet the following requirements:– KEYMARK certified and tested to DIN EN 215.
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.
The Standard thermostatic valve bodies are used in two-pipe pump heating systems with normal temperature spread. The double O-ring sealing and the the valve body made of corrosion-resistant gunmetal ensure a long-life and maintenance-free operation.
*) SW1: DN 10 = 22 mm, DN 15 = 27 mm, DN 20 = 32 mmSW2: DN 10 = 27 mm, DN 15 = 30 mm, DN 20 = 37 mm
Values H1 and H2 are at the bearing surface thermostatic head or actuator.
Kvs = m3/h at a pressure drop of 1 bar and fully open valve.
