Product Description
I. Product Overview
The LT - 16 electric wafer - type butterfly valve is a valve that drives the disc to rotate through an electric actuator, achieving the interception or flow regulation of pipeline media. The wafer - type connection allows it to be conveniently installed between two pipeline flanges. It is applicable to a variety of industrial scenarios and can meet the control requirements of different media.
II. Structural Features
- Compact and Lightweight Structure: It adopts a center - line disc and short - structure steel plate welding structure, which is small in size and light in weight. This makes it easy to handle and install, reducing labor intensity and installation costs while saving space.
- No - Linkage and No - Bolt Design: There are no vulnerable components such as linkages and bolts inside, reducing failure points, and ensuring high work reliability and long service life.
- Multi - Position Flexible Installation: It is not restricted by the flow direction of the medium and can be installed in various positions, adapting to complex pipeline layouts.
III. Technical Parameters
- Nominal Pressure: PN16 (indicating a nominal pressure of 1.6MPa, which can withstand a certain pressure, subject to specific working conditions and materials).
- Nominal Diameter: The common range is generally DN40 - DN2000, meeting the requirements of pipelines with different diameters.
- Applicable Temperature: Usually depends on the materials of the valve body and seals. Generally, it is around - 15°C - 150°C (for high - or low - temperature working conditions, special materials are required).
- Power Supply Voltage: The standard is 220V AC single - phase. Options also include 110V AC single - phase, 380/440V AC three - phase, 24V/110V/220V AC, etc.
- Output Torque: Generally in the range of 50N·M - 2000N·M, depending on different specifications and actuators.
- Actuation Range: The disc rotation angle is 0 - 90°, corresponding to the valve's closed to open state.
- Actuation Time: Such as 15s/30s/60s, etc. (depending on the performance of the actuator).
- Protection Level: Commonly IP67, which can prevent dust and water immersion, adapting to various environments.
IV. Main Parts Materials
- Valve Body: Common materials include WCB (carbon steel), CF8 (stainless steel 304), CF8M (stainless steel 316), etc., selected according to working conditions and corrosion - resistance requirements.
- Disc: Materials are similar to those of the valve body, such as carbon steel, stainless steel, etc. Some require special treatment to enhance wear - resistance and corrosion - resistance.
- Valve Stem: Usually made of stainless steel materials such as 304, 316, 1Cr13, etc., to ensure strength and corrosion - resistance.
- Seals: Such as ethylene - propylene - diene monomer rubber (EPDM), etc. They have good sealing performance, are resistant to aging and corrosion, and different seal materials can be selected according to the characteristics of the medium.
V. Actuator Characteristics
- Diverse Control Modes: It is equipped with on - off position lights (on - off two - position control), which can visually display the valve's open and closed states; supports intelligent regulation (4 - 20mA analog signal control) for precise flow regulation; also has control modes such as passive contact signals and 1/5K potentiometers.
- Protective Functions: It is equipped with built - in over - heat protection and over - load protection devices to prevent the actuator from being damaged due to over - heating and over - loading, extending its service life and ensuring safe operation.
- Manual Operation Function: It is equipped with an emergency manual device. In case of power outages and other emergencies, the valve can be manually opened and closed to ensure the normal operation of the system.
VI. Application Fields
- Industrial Production: In industries such as chemical engineering, petroleum, metallurgy, and power, it is used in pipelines for various gas, liquid, and semi - fluid media to control the flow and pressure of the media, and to intercept or connect the media. For example, in chemical raw material conveying pipelines, petroleum refining unit pipelines, and power plant steam and water circulation systems.
- Construction Field: In the building water supply and drainage system, it controls the flow and cut - off of water, such as in tap water supply pipelines and sewage discharge pipelines; in the HVAC system, it regulates the flow of air and water, such as in the pipeline systems of fan - coil units and air - handling units.
- Environmental Protection Industry: Applied in sewage treatment plants, waste gas treatment facilities, etc., it controls and regulates the flow of sewage, waste gas, etc., ensuring the stable operation of the treatment process.
VII. Installation and Maintenance Key Points
- Installation: Install it between two pipeline flanges, paying attention to aligning the bolt holes; confirm the valve installation direction (although it is not affected by the medium flow direction, some have specific requirements); after installation, check whether the disc opens and closes flexibly and whether the actuator operates normally.
- Maintenance: Regularly check the sealing performance for any leakage; inspect the operation of the actuator, including power connections and control signal transmission; regularly check and replace vulnerable components (such as seals); keep the valve and actuator clean to avoid the accumulation of impurities and dust affecting performance.
