Ⅱ Main parameters and performance
◆Nominal pressure:
1.6Mpa；2.5Mpa；4.0Mpa
◆Working temperature:-20℃-150℃-300℃
◆Leakage: Hard seal: GB/T17213-2005Ⅳ Soft seal: GB/T17213-2005Ⅴ
◆Flow characteristic: Equal percentage Graph
◆Control voltage: 220VAC
◆Input signal: Signal for cutting:1) 220VAC 2) If the valvereceives the controlling impulse signal about 220VAC100ms, the cutting valve   is also as the regulating valve to using.

Ⅲ Ordering demands
1.When to make the order; please choose the correct model referring to the item Ⅳ   in the table. If not, you’d better provide the following information, such as the type, pressure, dimension, seal type, the main material, medium temperature, control voltage(220V). The action type is formally electric to open. If not, you could note it, including the special demands, such as in the anti-explosion area.
2.The choosing accessories;
(a) Non-contacted limit switches
(b)1KΩ   potentiometer
(c)The material of connecting flanges; A3 (Carbon steel) /304SS

Ⅳ ZKRR series electric O-type cutting ball valve: the connection type is flange connection type and the standard of flange is GB9119.8-88

Ⅴ The compiling specification of series products’ model;

Ⅵ 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.

Ⅶ Principle of operation
The electric O-type cutting ball valve is made up of electric actuator, valve body, connecting and fastening pieces and so on. The signal (e.g., 24VDC, 220VAC) from the controlling instrument or manual tool operating will control electric actuator, 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 for driving the O-type valve trim.
The operational principle and installing drawings of electric actuator are seen in concerned specifications (such as from KOEI, PSQ, ULLI Company).

Ⅷ 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 electric O- 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.
◆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 electric actuator and the lower end of the box, which is used for adjusting the position from fully open to fully close.

Ⅸ Storage
Control valve had better be kept in the room among 5℃-40℃ temperature and ≤90% in the humidity. You’d better make sure there are no corrosive characteristics and other bad components in the air.

Ⅹ 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.
