Valve body
Tasted and sertified by the TUV, Garlock valve bodies meet the requirements against internal pressure according to the DIN 3840.
Flange design
Depending on the mounting situation all diameters and liner types are available in both, wafer body or lug body design.
Lining
Void free lining of 3 mm min. is guaranteed. High desity and sructure of the crystals in the lining components protect against permeation. Provides superior service life and economical advantages.
Body materials
Ductile iron GGG 40.3 according AD-leaflet W 3/2.
Heat resistant ferrite cast steel GS-C 25 according AD-leaflet W5.
Special steel casting 1.4581 according AD-leaflet W5.
Materials
The GAR-SEAL valves are available in fore different liner matirials. Discs are available in different metals, too. For all opereting conditions a unit quality and safety level is guaranteed.
Valve stem packing
