Carbon steel flange lifting check valve is a kind of valve that automatically opens and closes the valve disc by relying on the flow of the medium itself to prevent the medium from backflowing. Here are some of the key product features and technical specifications:
1. **Product Overview**:
- The disc of the lift check valve moves parallel to the axis of the seat, which makes the valve less impactful when closed and less prone to water hammer.
- The disc can be an all-metal construction, or it can be inlaid with rubber pads or rubber rings on the disc holder to suit different sealing needs.
- The valve is widely used in petroleum, chemical, pharmaceutical, electric power and other industries under various working conditions.
2. **Technical Specifications**:
- DN400
- Pressure rating: PN40
- Operating temperature: -29°C to 425°C.
- Body Material: Carbon Steel
- Disc/stem material: Carbon steel
- Test standard: GB/T12224
3. **Materials and Media**:
- The body material is WCB(C), which is suitable for water, steam, oil, nitric acid, acetic acid and other media.
- Operating temperature depends on the material and design, but generally ranges from -29°C to 425°C.
4. **Installation & Use**:
- It should be preferentially installed on horizontal pipes, but it can also be installed on vertical pipes.
- Clean the inner cavity to remove grease and ensure that the disc surface is clean before installation.
- The flow direction of the medium must be limited, and the medium passing through the line should not carry hard particles to avoid damaging the sealing surface.
- Inspect and test each unit before leaving the factory, and the installation unit can directly carry out the pressure test or install it.
5. **Application Scenario**:
- Pump outlets: prevent media backflow and protect the pump and piping system.
- Compressor outlet: Prevents gas backflow and protects the compressor.
- Various industrial piping systems: used to control the unidirectional flow of media and prevent backflow.
