GE V4562076-0200 Check Valve
GE V4562076-0200
1. Overview
GE V4562076-0200 is part of the imported wafer-type check valve series. It adopts a wafer-type structure to achieve one-way fluid control and is widely used in pipeline systems for high-pressure or high-temperature working conditions in industries such as petroleum, chemical engineering, metallurgy, and electric power.
2. Specifications
- Connection Type: Flange connection
- Operating Pressure: PN 16 ~ PN 25
- Operating Temperature: -30 °C ~ +250 °C
- Material: The valve body is usually made of carbon steel, alloy steel, or stainless steel; the sealing surface is made of cemented carbide or polytetrafluoroethylene (PTFE)
- Fluid Medium: Water, steam, oil products, acids, alkalis, etc.
3. Product Features
- Wafer-type structure enables quick assembly and disassembly without welding, facilitating on-site maintenance.
- Reliable sealing with a double-seal design to prevent leakage.
- Compact structure and relatively light weight, suitable for installation environments with limited space.
- Optional electric or pneumatic actuators for automated control.
- Certified by quality management systems such as ISO 9001 and CE, complying with international standards.
4. Structure and Components
- Valve body (with flange connection)
- Wafer-type valve cover and valve seat
- Sealing elements (cemented carbide or PTFE)
- Handwheel or actuator (electric/pneumatic)
- Accessories such as flange bolts and gaskets
5. Application Fields
- Petroleum and Chemical Industry: Anti-reverse flow protection for crude oil, finished oil, and natural gas transportation systems.
- Electric Power Industry: Check valves for boiler feed water and steam systems.
- Metallurgy and Iron & Steel Industry: Flow direction control of high-temperature and high-pressure media.
- Food and Beverage Industry: Check valves that meet hygiene requirements.
- Other industrial pipelines requiring anti-reverse flow functionality.
6. Installation and Maintenance
Installation
- First, check whether the valve body, valve cover, and sealing surface are in good condition.
- Use compliant flange bolts and gaskets, and tighten them evenly according to the specified torque.
- Confirm that the valve direction mark is consistent with the pipeline flow direction.
- If an actuator is used, complete the electrical or pneumatic wiring in accordance with the manufacturer’s wiring diagram.
Commissioning
- Conduct a closure test before fluid flow to check for sealing leakage.
- If an automatic actuator is used, calibrate the stroke and response time.
Maintenance
- Regularly inspect the valve body appearance and bolt tightness.
- Replace the sealing elements every 6 to 12 months (the interval can be appropriately extended based on the corrosion degree of the medium).
- Lubricate the electric/pneumatic actuator and inspect its circuits.
- In case of leakage or jamming, first disassemble the valve cover to check the wear of the sealing surface, and replace the valve body or valve cover if necessary.
