Application

Flanged jacketed ball valves are isolating valves designed to fully open or close the service fluid flow. These valves are used when the service fluid is solid at ambient temperature (e.g. Sulphur or bitumen) and it is necessary to keep the fluid liquid to operate the valve. Steam or oil is used as heating medium which allows to heat up the service fluid above it's melting point thus enabling operation of the valve. They are not designed to be used for throttling or regulating purposes.

The scope of application of the ball valve depends directly on materials and on design of the basic valve that is jacketed. Maximum temperature of heating medium must not exceed maximum working temperature of the valve itself.

It is possible to equip whichever ball valve from KE-ARM production range with a heating jacket, i. e. straight ball valves, three-way, high temperature, ball valves according to EN or API standards etc. The ‚-HJ‘ code is added to the valve's type to distinguish the jacketed valve (e.g. wafer type ball valve with soft seats has a code KM 9107.1–01, with a jacketed modification it is KM 9107.1–01-HJ.

Approved for fluids in groups 1 (hazardous) and 2 according to 2014/68/EU.

Considering the individual solution for each contract, it is impossible to specify all ball valve's parameters here. Do not hesitate to contact our office to get the quotation according your requirements.
