Electric Ball Valves. Typically used for ON/OFF control of water, air, oil and other compatible media. MTD electric ball valves use an electric actuator to open and close the valve. These valves are power-to-open and power-to-close. Valve positioner and fail close options are available.
What Is a Motorized Ball Valve? MTD Ball valves use motors to rotate a ball with a hole in the center to control flow. When the hole is in line with the flow, the valve is fully open, and when it is turned perpendicular to the flow, it is closed
The basic construction of an electric actuator consists of an electric motor, a screw, a nut and possibly gears if the electric motor is a small motor. In an electric actuator, it is the nut that provides the translation from electrical motion to mechanical motion when it rotates along the screw, moving forward instead of rotating along with the screw. Rotary electric actuators rotate from open to close using butterfly, ball in UPVC, SS, Cast iron material.With the use of rotary electric actuators, the electromagnetic power from the motor causes the components to rotate, allowing for numerous stops during each stroke. Either a circular shaft or a table can be used as the rotational element. The actuator torque refers to the power that causes the rotation, while the full range of motion can be either nominal, quarter-turn, or multi-turn.
Type of Electric Valve
Actuator The part of a valve that converts electrical, fluid or thermal energy into mechanical energy in order to open/close the valve.
Why do we use actuators? In engineering, actuators are frequently used as mechanisms to introduce motion, or to clamp an object so as to prevent motion. In electronic engineering, actuators are a subdivision of transducers. They are devices which transform an input signal (mainly an electrical signal) into some form of motion.

Electric Actuators Electric actuators are devices that produce rotary motion through the conversion of electrical energy into mechanical energy. This type of rotary actuator is typically attached to valves that move as a result of an outside power source. The necessary power level is achieved through the use of single-phase or three-phase AC or DC motors and various gears.
Benefits of Electric Actuators Many electric actuators are designed with easy-to-use interfaces. This innovation is partly because the actuators are engineered for different programming cycles and procedures. Enhanced controlling is ideal for conditions that require flexibility such as fast paced production environments. Manufacturers and consumers are realizing electric actuators are capable of replicating the same functions as of hydraulic and pneumatic actuators. Electric actuators also save more money in the long run due to less clean up costs that are normally associated with hydraulic fluid spills.
Electric actuators are becoming more ideal for medical applications that require precision and reliability. Newer models have a smaller structure that allow for easier assimilation into existing systems but there is no compromise for performance. There are also extra benefits due to the combined capabilities; the user can trust a single source when performing those crucial medical applications. As time becomes a premium it is essential that components are going to function at optimum efficiency.

What is a motorized control valve? MTD Motorized control valves allow for flow to be stopped, started, and adjusted as necessary to ensure that operations continue as scheduled. Motorized control valves work to control flow by either opening or closing an opening within a pipeline. When the valve is open, liquid is able to pass through freely.
What does a valve actuator do? MTD Electric valve actuators control the opening and closing of valves. They can provide either linear or rotary motion and work with different types of valves, including ball and butterfly valves.
Safey Notice 1.Please pay attention to the ambient temperature 2.Not explosion proof product, do not use them in flammable and explosive environment. 3.When power on, it is not allowed to do wiring. 4.When installing, you need to consider the reserved space for wiring and repairing.
Electric Valve Selection Guide

What is Rotary Electric Valve and Linear Electric Valve?
The electric actuator is generally divided into rotary actuators and linear actuators according to their motion modes. Both of them are composed of servo amplifier and actuator, one of which outputs angle (torque) and one of which outputs displacement (thrust) . The function of the linear actuators and rotary actuators electric actuators is to receive the standard current signal of 0~10, 4~20 mA or 1~5 V voltage sent by the regulator or other instruments, which will become displacement thrust or angle torque after passing through the actuator to operate switches, valves, etc. to complete the task of automatic adjustment.
Most of the rotary electric actuators and linear electric actuators are modified on the basis of the multi turn electric actuator type: based on the multi turn type, a 0~90 °rotary electric actuator is composed of a worm gear two-stage reduction box; A linear electric actuator is composed of a screw rod component.
Difference: 1. Different industries: The rotary actuators electric valve is used to control the 90 degree rotation so as to achieve the on-off of the valve. The rotary electric actuator is used together with the ball valve, plug valve and butterfly valve, and can rotate for a quarter or more of a turn from opening to closing. Rotary electric valve controllers are used in power industry, high-power switch gear and packaging applications.
Linear actuators is to realize the up and down movement of the valve plate, which is usually used on equipment with high degree of automation.
2. Different types: Rotary actuators valves include electric ball valves, plug valves, electric butterfly valves, and other rotary actuators valves. Linear actuators valve includes stop valve, electric gate valve, slide valve, etc.
3.The movement mode of the valve core is different: the valve core of the rotary actuators valve rotates with the valve stem at an angle perpendicular to the valve stem. The linear actuators valve drives the valve core to rise and fall vertically to the valve stem through the valve stem.
Flow resistance and kv value The medium flow path of the linear actuators valve is complex and S-shaped, so the flow resistance is large and the flow capacity is small, so the flow coefficient Kv is small. The medium flow path of Rotary Actuators valve is simple, so the flow resistance is small, the flow capacity is large, and the Kv value is large (the kv value is 1.5-3 times larger than that of linear actuators valve).
Sealing performance The linear actuators double seal valve has upper and lower valve seats, but the axial size of the double seal valve core cannot be absolutely equal to the axial size of the two valve seats. When the upper valve core and valve seat contact, there is still a gap between the lower valve core and valve seat, or when the lower valve core and valve seat contact, there is still a gap between the upper valve core and valve seat. As a result, the leakage of the double seal valve is large, coupled with the impact of thermal expansion, this situation is more serious. For rotary actuators valves, especially ball valves, the leakage is small because the valve core is spherical, tangent to the sealing surface and in good contact. Packing with better sealing performance can also be used to improve the sealing performance of rotary actuators by 2-3 times compared with that of linear actuators.
