ZSSV - T series pneumatic v-type regulating ball valve

Ⅰ Summary
ZSSV-T series pneumatic V-type hard seat regulating ball valve consists of double action actuator, V-type ball valve, and valve’s positioner and so on. It is received the control signal (4-20mA) from DCS, QCS, PLC and regulating instrument, which compare to the feedback from positioner. The outputting air pressure signal from positioner would operate the piston inner the cylinder of actuator. Then, turn the valve trim of V-type valve until the signal being pro data. The changes from the valve trim will change the sectional area of valve’s flowing to up to the purpose for regulating. Because it is following the   V-type trim, which has better sealing and cutting function. It is used for process controlling in the lots of industry areas, such as pulp paper, food, medicament, metallurgy, petroleum and chemistry, electric power ,sewage disposal industries and so on, especially for the medium of high viscosity and with fiber and small grain.

   2) Induction switches (24VDC/220VAC) 
   The material of connecting flanges;
    A.A3 (Carbon steel)
    B.304SS
   3) The choosing positioners’ type;
    A. SVP-2000A from Jilin Haike CO.
    B. NELES 700 series or ND9100H series from METSO Company
    C. TZID-C series from ABB Company
    D. SIPART PS2 series from SIMENS Company
    E. YTC series (YT-1000R) from BELLOFRAM Company.
    F. PE400 series from SOMAS Company
    G. EP2400 series from HONEYWELL Company
    H. DVC6000 series from FISHER Company
    I. CHX series from Changshu Huaxia Company
    J. AVP3000 series from YAMATAKE Company  
4.If the valve would be used in the anti-explosion area, please note it while you make the inquiry. 
5.If the material of the seat is soft seat, you should note it because the common seat is metal seat.
 

Ⅴ Safety
ⅰ We make sure all the valves is very safe only if the material and pressure accord with the requirements in your order.
ⅱ According to the 4th part in the national standard(GB/T17213-2005/IEC60534-1999) of control valves industry area, it is the    examination and testing on duty. We have test and examined the pressure and material following the testing report so that we are sure    the safety of valves. The technical demands as followed,
1.Material testing
The physical test and chemical composition of the material for producing control valves accord with the standard of control valve or   the concerned requirements in the order.
2.the static pressure testing in the liquid
All the compositions of control valve, even no actuator, which must be finished the static testing in the liquid according to the   concerned pressure. i.e. it is tested by 1.5 times to the rating pressure.
 
Ⅵ  Principle of operation
The V-type regulating ball valve is made up of pneumatic actuator, valve body, and valve’s positioner, air filter, connecting and fastening pieces and so on. It finishes the position controlling from full open to full close by the valve’s positioner. Then, the signal (e.g., 0-10Ma, 4-20Ma,20-100K) from the controlling instrument or manual tool operating will control the valve’s positioner, which output the signal of air pressure at once to impulse the actuator so that it finishes the position controlling from open to closed by the wheel box to drive the V-type valve trim. The changes of valve’s position make the area of flowing changed so that it is up to the purpose for controlling flowing.
 
Ⅶ Installing, usage and maintenance
◆The position of installing the ball valve would be in the place as standing by the building platform 、a walking block ect. in order     to having the best watching、adjusting、Operating、maintenance and repairing. 
◆The pneumatic V- type ball valve may horizontal fix or vertical installing. 
◆When to install the valve body, the medium must be flow to in a direction from the arrows on the valve body. The control voltage is     either 24VDC or 220VAC.
◆You would be added to lube oil in the wheel box of the actuator and the joints for half year at least. 
◆The waste materials should be removed before installation of piping systems. Once installed, the position of the valve body must be     opened completely to sweep by blowing the wind into a pipeline. 
◆There are two screws(M12 ～ M20)  on the upper end of the cylinder of the pneumatic actuator and the lower end of the box, which is     used for adjusting the position from fully open to fully close.

Ⅷ Storage
Control valve had better be kept in the room among 5℃-40℃ temp. and ≤90% in the humidity. You’d better make sure there are no corrosive characteristics and other bad components in the air.
 
Ⅸ Packing and transportation
The packing material must accord with the concerned packing standard and demands. The packing must be intact and whole. It should have the own symbol against rain or dust and how to lay up. You should prevent the strong shaking in order to protecting the packing well in the journey of transportation.
