JC offers also a large range of metal seated ball valves for diferent services (slurries, pulp and liquors, high temperature, abrasive or sticking fluids, control).

What is HT-65?
HT-65 is a thermal-chemical diffusion process where ferrous parts are heat treated at 565 ºC (1050 ºF) through an appropriate formulation to assure the interface of the materials being processed. The intrinsic properties of HT-65 are its low coefficient of friction as well as the degree of lubricity in both the dry state as well as under lubrication. This highly lubricious process prevents stainless steel from galling and, once HT-65 is applied, the surface becomes Rockwell 70 in hardness on the “C” scale.
The HT-65 layer is highly resistant to wear, seizure & corrosion. Tipically HT-65 penetrates the ferrous matrix to a depth of 0,2 to 0,25 mm (0,0079 to 0,01”) to form the diffusion zone. Austenitic steels develop an extremely hard & complex compound zone distinctive from all ferrous metals, typically 17 to 22 microns (0,0007 to 0,0009”) thick and a difussion zone approximately 76 microns (0,003”) deep.
HT-65 components have excellent sliding and running properties, a very low friction coefficient that minimizes the incidence of abrasion due to wear and galling.
With HT-65, JC can assure a bubble tight sealing up to temperatures of 327 ºC and Class V up to 500 ºC.
