Three piece ball valves

Three piece ball valves are widely used in all industries, where are handled different mediums. These valves have made a good showing in heat and gas supply, petrochemistry, pulp and paper industry, paint and varnish plants, petrol station, in heat and nuclear plant’s systems. Minimal resist, for this reason valve is suitable for viscose medium. Excellent sealing system makes these valves extremely reliable, especially during operation with abrasive liquids. By the customer request valve can be supplied with different actuators type. Moreover, valve can be supplied with heating jackets, extended spindle ant etc.

 

Applications: nitrogen, ammonia, fuel oil products (lube oil, benzene, kerosene, diesel oil, heavy oil (mazout)), butane, water, steam, acetone, hydrogen, oxygen, ethyl alcohol, methyl alcohol.


Materials: cast iron, steel, stainless steel.


Connection type: welded, long welded, flanged or socket.


  • Temperature range from -60 °С up to +500 °С
  • DN 25-500
  • PN 10-63

 

Maintenance-free (one piece) ball valves

Valve tightening and lubrication is not required. Long-lasting, short time for installation, low maintenance costs. Isolation works are easy because of high spindle with valve’s external round shape. Valve’s removable handle can be moved 180 degrees. The construction doesn’t have heavy and weak casting parts. Drive gear is easy to mount even after instalation.

Applications: natural gas, hot gas, steam, water, hydrogen, drainage and air offtake cutting off.

 

Materials: steel, stainless steel, carbon steel, CrMo low-allot steel.


Connection type: welded, long welded, flanged, clamp.
