Surface treatment:
Valve body and fittings are nickel-plated.
Marking:
THE, country code, flow direction arrow, DN and KEYMARK-Designation. II+ Designation.
Orange protection cap.
Standards:
Valves meet the following requirements:
– KEYMARK certified and tested to DIN EN 215, series D.
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:
HEIMEIER M30x1,5
