Features:
Electric motor
The rated voltage of the motor, the switch type is 110/220VAC/1/50 (60) Hz, which is a reversible induction motor. (The built-in thermal overload automatic reset protector for the motor). The regulated 110/220VAC is a series-excited rectifying motor. The switch type and regulation type of 12/24VAC / VDC are series-excited rectifiers. A three-phase motor is also available if required.
Gear set
The gear set consists of a precision tangent multi-stage gear and shaft. The gears and shafts are made of heat treated high alloy steel with self-locking. The main gear system is permanently lubricated at the factory.
Handwheel operation
Manually operate the unit and manually operate the valve position when the power is turned off.
Travel limit
The standard configuration is a 2-pair single-pole double-throw switch 220VAC/10A, one pair for AC motor control and one pair for passive position feedback.
Cam/cam adjustment
The cam can be adjusted directly with a hex wrench without special tools. The end of the trip is generally set at the factory from 0° to 90°. It can also be set to an angle of adjustment of 180°, 270° or more.
Valve status display
With a high-definition valve status display, the display is made of steel construction material and has good corrosion resistance. The mark is obvious and the color is bright - yellow is on, red is off, and the valve status is displayed throughout, providing a clear position display.
Heater
Constant temperature control prevents moisture condensation inside the actuator and protects the electronics. The terminal is preset to be connected. Terminal block The actuator switch is pre-wired to the terminal section. The terminal part is simple to wire and clearly marked with a number. This part is located at the two wiring entrances and exits, and has sufficient wiring space for customer wiring. Inside the enclosure.
Shell
The cast aluminum cover and housing are water resistant (NEMA 4, 4X, 6 and IP67) with a high quality grey epoxy coating to prevent erosion, abrasion and bumps.
Wiring entrance
Two 1 / 2" NPT or M20 mm metric pipe connectors for power and control lines. Mechanical travel limit standard configuration with mechanical travel limit to limit valve rotation to 0° on and off It is between 90° and can be adjusted without opening the end cap during operation.
Server
Precise control of valve position (less than 2% error), including a circuit board and a combination of feedback potentiometers. There is a separate terminal section for customer field wiring and other terminals and device connections inside the drive. The feedback potentiometer is driven by a set of gears connected to the output of the actuator drive. The input signal is 4-20 mA 210 VDC, 1-5 VDC. Output signal 4-20

Terminal block The actuator switch is pre-wired to the terminal section. The terminal part is simple to wire and clearly marked with a number. This part is located at the two wiring entrances and exits, and has sufficient wiring space for customer wiring. Direct mounting inside the housing The S74 actuator can be mounted directly on the valve of Bray without any external connection structure. The field installation is easy and will not be misplaced. This design reduces the space requirements for installation and prevents accumulation of impurities between the actuator and the valve.
Accessories (optional)
2 adjustable torque switches The single-pole, double-throw mechanical switch is factory calibrated. Independently reacts to the overload on the two strokes on/off, cutting off the motor power. It is also possible to operate at any point in the actuator travel and shut down the unit when the load exceeds a previously set value.
Feedback potentiometer - feedback information that continuously indicates the position of the valve.
Local control - device power indicator, on/off indicator, on/off switch, and field/remote switch. Certification ISO9001 CE CSA-
