2 eifang ctuators Summary pplicability They provide a reliable position control of butterfly, ball valves, as well as similar ones. Torque Power 0V / phase / 50z; 80V / phase / 50z eatures bout us Tianjin eifang Valve ctuator o., td. for short always focus on the design and manufacture of excellent valve actuator and control equipment. attaches great importance to product design, and the design team has strong product design and innovation ability. has complete intellect ual property rights and a number of technical patents. Over the years, our products have been annual exported in batches and were widely and successfully used in water treatment, oil, electricity, chemical and other industries. acquired the authentication of quality management system standards ISO9000 of V in 998. Strict quality control in all stages and constantly improving the product quality control standards is the consensus of the staff. believes that only solid the software and hardware foundation to achieve long-term stable development. We have set up some advanced computer-aided system, such as product design, resource management, production management, and so on. nd we have set up the platform of precision machining mainly based on machining center. We also continue to establish and improve a documented management system. will design and manufacture products solidly and continue our efforts to create more value for customers. 4 5 Thanks to computer tools, 80 series are designed with an outstanding structure and concise, meticulous appearance. egerity 80 series are more lightweight for the die-casting aluminum case. Waterproof The protection grade reaches IP68 by using the rubber sealing ring in all jointing surface. Quiet The two-stage worm gear and worm driving ensures 80 series operating smoothly and quietly, so 80 series are especially suitable for environment of phase power supply. Usability Some unique designs such as the tridimensional valve position indicator and the spring-return and concealed hand/auto switch make 80 series easier to be operated.

3 80 series eifang ctuators Structure The tridimensional position indicator is easier to view from the side. nd the valve position can be seen at a distance for the dial surface is coated with red and yellow. In addition, the viewing window can be adjusted to the appropriate position. The excellent heat-sinking motor can be dismantled. If the motor windings overheat, a temperature protection switch embedded in the windings will cut off the power. imit switch: Once the valve run to the right place, the cam set on the limit shaft which remains in step with the drive sleeve will drive the microswitch to interrupt the power or transmit signals. Torque switch: The axial move of the worm shaft which mounted with the disk spring is proportional to the torque generated by the actuator. The torque switches can sense the movement and interrupt the power or transmit the over-torque signals. The worm and worm gear are directly driven by motor, so the product runs noiselessly. utomatic reset hand/auto switch: y operating the switch lever, manual drive is engaged. nergization of the motor automatically re-engages power operation. handwheel is provided for setting or manual operation when power failure. or the worm and worm gear is self-locking, the valve can be maintained in place when the operation stops. The motor and all control elements are arranged above the steel plate, so it is convenient for debugging and maintaining. The removable drive sleeve which splined with the output shaft is convenient to install. The drive sleeve can be flexibly machined to match the valve stem. able gland Two adjustable mechanical stop bolts in open and close direction are provided for limiting the travel of the drive sleeve. s the smallest unit of 80 series, the 800 product with a compact shape can match the small diameter valve. In addition, the 800 unit without torque switch 0 The switch lever is located at the bottom of the unit to avoid being knocked against. is designed with a spacesaving hand/auto switching mechanism. 0

4 80 series onfiguration and function Ordinary products comply with /T4 Technical specifications of basic version electric valve actuators. xplosion-proof products comply with /T4 Technical specifications of explosion-proof version electric valve actuators. mbient temperature otor 80 series adopt special?motor for valve with high torque low inertia. or the stator is exposed, the motor has good heat dissipation. uty of motor as follows: S-0 S4-5% The continuous running time of the motor is less than 0 minutes Travel range and it will not start again until the motor surface cooled to ambient temperature. This kind of motor is used for operating the valve full open or full close. The proportion of each working time and working cycle the interval between two starts is not more than 5%. This kind of motor is the standard configuration for the modulating type. eifang ctuators ow temperature asic and integrated type -0~+70-40~+60 xplosion-proof type -0~+40-40~+40 Options egree of protection Options x degree ubrication oating Power supply able gland IP Protection from dust and sprinkling.

The epoxy powder electrostatic spraying surface has excellent corrosion resistance. 4V power supply. imit switch The mechanical limit switch ensures the cam and the drive sleeve coaxially and synchronously. 80 series supplied two switches of 50V 6 in open/close direction respectively. Torque switch 80 series adopted mechanical torque switch and supplied two switches of 50V 6 in open/close direction respectively. It has not torque switch in 800 product. anual operation quipped with automatic reset hand/auto switch and some manual operation parts, ensure safe operation. mong them: 800 product is designed with a hidden hole to be used for manual operation with a spanner supplied with the product. Insert the spanner into the hole to manual operation and drawing out the spanner will automatic reset the power operation. 80~80 series are equipped with a handwheel and an auto/hand switch lever, turn the lever will drive the clutch out of the electric position and the manual operation can be carried. nergization of the motor will automatically re-engage power operation. Position indication The tridimensional mechanical position indicator keeps in step with the drive sleeve. echanical stops One adjustable mechanical stop bolt in open/close direction respectively is supplied.

VPT Two-wire system valve transmitter which output 4~0m signal. 80P 5 T 4 07 Integrated type The control package integrates the reversing startup of motor, input and output signal processing and all protection functions. ) Provide a local/remote selector and a local open/close operator; ) In remote state, it can communicate with upper computer, receive the on-off signals of opening or closing valve and feedback the valve position and passive contact signal of torque; ) Provide functions of phase sequence identification Prevent valve operating to the wrong direction because of wrong phase sequence phase-loss and overcurrent. Proportional modulating 80 series can proportional modulate the valve according to the received 4 ~ 0m control signal. ) It can achieve the best control precision by the adaptive algorithm. Usually the steady state control precision is higher than %. ) Isolated output 4 ~ 0m valve position signal percentage. ) Setting of open mode: In general, 4m corresponds to full close position, 0m corresponds to full open position. If need, this paramete r can be set with 4m corresponding to full open position, 0m corresponding to full close position. 4) Setting of signal loss action action of 80 series when control signal loss : keep in place, full open or full close. 5) The sensitivity can be set. When the valve inertia is larger or the load changes dramatically, for tracking control signal, the electric mechanism may start repeatedly, which is shock phenomenon. Reduce sensitivity can effectively eliminate the shock. There are two ways to achieve proportional modulating function for 80 series: dd the proportional control unit in integrated type products, which cover all 80 series. quipped with proportional regulating module in basic type products, which applies only to actuators with single-phase power supply except 800 product. ull ull 6 S T onnection ways and code for valve Wiring diagram Work environment: ow temperature unctions: Proportional modulating Provide VPT for outputting position signals Power supply: Single-phase power supply Three-phase power supply power supply Output torque, unit odel x0m 06 07
