Hard sealed flange electric gate valve

1 Z941H-25C DN300Hard sealed flange electric gate valveProduct Overview:

Electric hard seal flange gate valveThe opening and closing component of the gate valve is the gate valve, and the direction of movement of the gate valve is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and is not suitable for adjustment and throttling. The gate valve has two sealing surfaces. The two sealing surfaces of the commonly used wedge gate valve form a wedge shape, and the wedge angle varies with the valve parameters, usually 5 degrees. The gate of the wedge gate valve can be made as a whole, called a rigid gate valve; It can also be made into a gate that can produce slight deformation to improve its processability and compensate for the deviation of the sealing surface angle during the processing. This type of gate is called an elastic gate.?

II Z941H-25C DN300Hard sealed flange electric gate valve?Structural features:

1. Gate valve is one of the shut-off valves, mainly used to connect or cut off the medium in the pipeline; Gate valves are suitable for a wide range of pressure, temperature, and diameter, especially for medium and large diameter pipelines.
2. The wedge-shaped rigid single gate structure is simple, small in size, and reliable in use. It is suitable for various media and pressure environments at room temperature and medium temperature. Widely used in industries such as water supply and drainage, gas, electricity, metallurgy, petroleum, chemical, textile, and urban construction, it is used for opening and closing pipelines for steam, water, and oil media.
3. Low fluid resistance. The internal medium channel of the gate valve body is straight through, and the flow direction of the medium through the gate valve does not change, so the flow resistance is relatively small.
4. Opening and closing are relatively effortless. The direction of the gate movement during opening and closing is perpendicular to the direction of the medium flow. Compared to globe valves, gate valves require less effort to open and close.
5. The direction of medium flow is generally not restricted. The medium can flow in any direction from both sides of the gate valve, achieving the purpose of connection or disconnection. Easy to install, suitable for pipelines where the flow direction of the medium may change.

3、 Characteristics of the actuator:

1. Power supply: The motor is three-phase AC, 380V (special order 660V or 220V), 50Hz (special order 60Hz); The control line is 220V, 50Hz (special order 60Hz); Remote control is 24VDC.
2. Work environment:
(1) Environmental temperature: -20 to+60 ℃ (special orders -60 to+80 ℃).
(2) Relative humidity: ≤ 90% (at 25 ℃).
(3) Ordinary and outdoor types are used in places without flammable/explosive and non corrosive media; There are two types of explosion-proof products, dI and dIIBT4. dI is suitable for non mining working faces in coal mines; DIIBT4 is used in factories and is suitable for explosive gas mixtures in IIA and IIB level T1 to T4 environments.

4、 Assembly requirements:

1. Assembly tools must be degreased and cleaned before assembly to ensure cleanliness;

2. Assembly workers must wear clean pure cotton work clothes, a pure cotton cap, no hair leakage, clean shoes, plastic gloves, and degreased hands;

3. The installation workshop must be kept clean or a temporary clean area must be set up, such as using newly purchased colored cloth or plastic film, to prevent dust during the installation process;

4. The assembled valve should be purged with nitrogen for at least 1 minute;

5. After passing the airtightness test, seal it with a clean polyethylene cap. The polyethylene cap should be organic before use.
