PURPOSE AND SCOPE

Valves are used as locking and locking-controlling arms in the processing lines of the enterprise of pulp and paper, chemical, by-product coking, petroleum, metal and other industries. On hostile environments and environments containing abrasive: salt solutions, alkalis, acids, slurry, sludge, etc. at the temperature up to 260°C. 

ADVANTAGES AND DETAILS OF CONSTRUCTION:

• plug (globe) is made of corrosion-resistant steel with application of a unique hard chromium electrolytic coating with thickness of not less than 100 microns, and a hardness of HRC 59 ... 62; seats are made of corrosion-resistant steels with application of a special wear-resisting stellite surfacing STL (HRCe 52…55) with hardness not less than 3 mm on the spherical surface of the seat, which ensures reliability and durability of the construction in high-abrasive and aggressive mediums;
• unique technique of fitting and bedding of plug and seat spherical surfaces provides getting of class from B to A hermiticity for metal-to-metal seal according to the GOST9544;

• 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.

Basic globe valve versions. Scheme of conventional symbols

Note:
A globe valve completing is possible with pneumatic drive and optional modules:
PR – pneumatic valve(24;220 V),
FR – filter-regulator,
RD – manual override,
KBS – quick release valve,
SKP – limit switch,
KMCh (installation kit): mating flanges, fittings, blotters.

Example of conventional symbol at the time of order
