Electric two-way valve actuators

1.LDX electric two-way valve actuators are suitable for each series of valves of the company's small size, it AC24V or AC220V single-phase AC power supply, can receive the control signal is proportional three floating point (double switch), proportional control analog control (0-10VDC, 4-20mADC) and floating voltage feedback, and other controllers. According valve bore and off pressure Select the driving force, but also can be matched with other manufacturers of valve body. Servo actuator design system (electronic locator), just direct access to DC4 ~ 20mA, DC0 ~ 10V or DC control signal own preset to work 2.LDX electric two-way valve actuator features 2.1 aluminum alloy selection stand, high strength and light weight. 2.2 adjustment is simple, easy to operate. 2.3 positioner accurate. 2.4 synchronous motor, low power consumption. 2.5 High Off output pressure. More than 2.6 kinds of input control signal selection, you can select switch selection criteria (DC4 ~ 20mA or DC0 ~ 10V) or non-standard (self-setting) control signal status. 2.7 Optional positive and negative effects. 2.8 with adaptive function, a key set of different caliber, zero and full bit different stroke of the valve. 2.9 can be set by the state selection switch off signal, valve is fully open, fully closed, or hold. 2.10 high resolution, and through key settings, up to 0.4% of the control accuracy. 2.11 triple protection, can play a protective role by mechanical, circuits, and software to prevent damage to the actuator itself. 2.12 with mechanical manual and electronic manual functions, make the operation more convenient. 2.13 overload alarm, when an overload Atropisomers, the locator LED blinks immediately and dry contact alarm signal is issued. 3.
