The article is based on the composite reinforced molded case.
Handle
The handle is made of stainless steel and has a safety shut-off, which ensures fixation in “open/closed” positions.
Body
The body material is polyphenylsulfone (PPSU)/glass-filled polypropylene (GFPP) – high-strength polymers notable for their high temperature stability and exposure to the aggressive media. Like other plastic materials, PPSU and GFPP are not corrodible. The PPSU characteristics as to their strength, shock resistance and reliability are equitable to metal. PPSU is UV-stabilized, hydrolysis-resistant and resistant to formation of deposits of solids.
Press-on bush
Press-on bush is made of stainless steel and is corrosion resistant to the aggressive media.
Sliding cylinder
The sliding cylinder is made of polyphenylsulfone (PPSU)/reinforced by
a stainless steel insert.
Bushing
The bushing fulfils the function of a ball cylinder through compensation of a radial load on the gland thus extending its operational life.
Ball seal valve
Chevron stem packing ensures a reliable packing at a low friction.
Thrust washer
The thrust washer ensures a low frictional moment.
Ball
The ball material is polyphenylsulfone (PPSU). In the ball design realized is the principle of a floating spigot, which ensures self-packing and the valve seat guide wear compensation.
Valve seat guides
The valve seat guides are made of polyphenylsulfone (PPSU). The valve seat guides ensure maximum filling of the parasitic space around the ball into which the working medium can penetrate.
Operation under the conditions of influence of the high
rate flow of the corrosive media (water, aqueous vapour, acids, organic substances, abrasive particles, petroleum products).
FUNCTIONS AND CHARACTERISTICS:
Operation by hand and from the electric drive.
The ball valves are in compliance with the requirements of GOST Standard 21345, GOST Standard 122063, GOST Standard 9544.
Oil producing industry, petroleum refining industry, gas industry, chemical industry, water supply, heat supply and sewerage networks.
