Basic technical data of the control cellular valves
|
Application The control cellular valves are stationary elements of automated control systems for technological processes and they are meant for controlling the flow discharge of the working medium in automated control systems for technological processes. The operation principle of the valves is based on the change of hydraulic resistance due to the change of the flow area of the control body by the movement of the closure plunger (slide). By the change of the hydraulic resistance there appears the change of the discharge capacity of the valves. The slide movement in the valves is made with the help of the executive mechanism, the shaft of which is rigidly attached to the closure plunger.
Characteristics Control cellular valves with the straightway body, balanced, with the flanged connection to the pipeline, with the pneumatic (PM), electrical (EM) or manual (MM) executive mechanism (drive). Rod seal – gland seal. Types of executive mechanisms: – pneumatic: pneumatic membrane-spring executive mechanism MEM1, pneumatic piston executive mechanism МИП; – electrical: electrical forward trace executive mechanism. Action type of the valves with the pneumatic drive: – normally-open (NO); – normally-closed (NC). The type of the discharge characteristic: – linear (L); – equal-percentage (E). The type of gasket in the closure: – “metal on metal” (MM); – “metal on elastomer” (ME); – “metal ceramic” (MC). Leak-proofness grade in the valve closure: – II according to GOST 23866-87 (the admissible leakage in the closure doesn’t exceed 0,5 % of Кvу), – III according to GOST 23866-87 (the admissible leakage in the closure doesn’t exceed 0,1 % of Кvу), – IV according to GOST 23866-87 (the admissible leakage in the closure doesn’t exceed 0,01 % of Кvу), – А or В according to GOST 9544-2005. The type of the climatic performance of the valves: – У1 according to GOST 15150-69, but for operation under temperature from minus 50 °C up to plus 50 °С. – ХЛ1 according to GOST 15150-69. The sound level, created by the valves, doesn’t exceed 80 dB·A. The valves can be equipped with additional units: a manual alternate, a pneumatic or electric pneumatic positioner, electro-pneumatic valve, limit switches, stabilizer-filter. By the customer’s order the valves can be supplied with the cooling (heating) jacket of the control body. |

Conventional designation of valves
The material of the basic parts, which directly touch the medium controlled, correspond to the material of the body, excluding the products with the bodies from carbon steel, in which the closure parts are made of steel 12Х18Н9(10)Т.
