A Electric Gate Valve, also known as a sluice valve, is a valve that opens by lifting a barrier (gate) out of the path of the fluid. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened.
Size Range: 2'' to 16''
Pressure Range: ASME CL, 150, 300, 600, 900, 1500, 2500
Material: Stainless Steel
One of the primary advantages of stainless steel gate valves lies in their corrosion resistance properties. Stainless steel, renowned for its resistance to rust and corrosion, ensures longevity and durability even in harsh operating conditions, making these valves suitable for a diverse range of industries and applications.
Moreover, stainless steel gate valves are available in various sizes, pressure ratings, and configurations, allowing for seamless integration into different piping systems. Whether in petrochemical plants, water treatment facilities, or industrial processes, these valves provide versatile and dependable fluid control solutions.
Electric gate valve: An electric gate valve uses an electric motor instead of a handwheel. By utilizing electrical power, the actuator spins the stem to raise or lower the gate. This allows it to be operated remotely with no user on-site but requires electrical power on-site. These are also referred to as motorized gate valves.
A gate valve operates similar to other valves. To open the valve, turn the handwheel (A), which moves the gate (G) up or down on the stem (B) via the threads. A gate valve requires more than one 360° turn to open or close the valve fully. When the gate is lifted up, it opens the inlet to the outlet allowing an unobstructed passageway for the media to flow. When the gate is lowered, it closes and blocks the media flow.
The relationship between the gate's vertical travel and the flow rate is nonlinear for a gate valve, with the greatest changes occurring near-complete closure. When used to regulate flow, the relatively high velocity of the flow at partial opening results in gate and seat wear, which along with possible vibrations of the gate, shortens the valve's service life. Therefore, a gate valve should only be used for on/off control.
If the following conditions can lead to Overload:
First, the power supply voltage is low, can not get the required torque, so that the motor stop turning,
Second, is the wrong adjustment torque limiting mechanism, so that it is greater than the stop torque, resulting in continuous generation of large torque, so that the motor stop turning;
Third, is intermittent use, resulting in heat savings Exceeding the allowable temperature appreciation of the motor;
Four, is due to some reason torque limit mechanism circuit failure, so that the torque is too large;
Five, is the use of environmental temperature is too high, relative to reduce the thermal capacity of the motor.
Six, the basic protection method of overload is:
1. To the motor continuous operation or point operation of the overload protection, the use of thermostats;
2. The protection of motor plugging and turning, the use of thermal relays;
3. For short-circuit accidents, the use of fuses or overcurrent relays.
