When viscous materials are handled, JC steam jacketed ball valves are recommended to prevent valve to be blocked in closed position.
The maximum steam jacket pressure is 10 Bar (1.0 Mpa) and maximum temperature is 260º.
Some of the roughest process controls problems involve fluids than can polymerize in place. That means they can polymerize inside body cavities and could block the valve. Cavity-filler seats are available in PTFE, Stansit, TFM.
Applications: Styrene, Butadiene, Monomers, Pharmaceuticals, Food process,...
Today’s concern for the containment of fugitive emissions has brought forth in the industry a wide range of stem sealing concepts and designs aimed to eliminating stem leakage. For these applications where it is imperative that fluid containment has to be assured, double packing can be adapted to any JC ball valve.
JC ball valves have been widely used in low temperature and cryogenic applications, including some gas treatment processes (LNG, Methane, LPG…), requiring valves able to be operated and to assure helium leakage rates within specified limits at low temperatures. In these cases JC offers valves designed with special seats, bonnets and materials for low temperature or cryogenic service.
JC Valves can be delivered with pneumatic, electric, hydraulic or gas-over-oil actuators as per customer requirements.
