Globe valves for high-temperature mediums
PURPOSE AND SCOPE
They are used as locking and locking-controlling arms of flow and fluid operating mediums: water, industrial water, steam, technological gases (oxygen, hydrogen, hydrogen sulfide, coke, domain), plant and technical oils, paraffin, oil products, carbohydrates, diesel fuel, kerosene, petrol, coking oil products at the temperature up to 450°С.
ADVANTAGES AND DETAILS OF CONSTRUCTION:
- unique technique of fitting and bedding of plug and seat spherical surfaces provides getting of class A hermiticity for metal-to-metal seal;
- a spring load construction of metal seat provides its hermiticity both at large and at small dimensions of operating pressure at differential temperature of operating pressure during the whole period of operation, and also prevents details jamming in the thermal expansion of valve details with the temperature of operating mediums up to 450°С;
- seat performance metal-to-metal allows using of globe valves both in locking and regular regime;
- globe valves have full-bore construction that minimizes hydraulic losses in pipeline and prevents runout of valve operating surface;
- valves are made in versions with manual (mechanical) drive, with pneumatic and electric drive.
