Product Features:
1.Temperature Grade Adaptability: According to different temperature grades, the extension size of the valve stem and valve cover is also different.
2. Cryogenic Treatment: For valves ≤101℃, cryogenic deformation is prevented, and the main parts should be cryogenically treated.
3.Erosion Resistance: The valve seat and valve disc sealing surface are welded with hard alloy to improve the valve's erosion resistance and extend the valve's service life.
4.Low Friction: The friction between the sealing surfaces is small during opening and closing, and the service life is long.
5.Various Valve Disc Shapes: The valve disc shapes are conical, needle-shaped, spherical, and parabolic, and can be used for regulating throttling.
6.Reliable Sealing Structure: SS+graphite or metal sealing or pressure self-sealing structure is used between the valve body and the valve cover, making the sealing reliable.
7.OS&Y Structure: The OS&Y design makes the valve opening and closing position clear, which is convenient for operation and monitoring.
8.Thread Protection: The valve stem thread does not contact the medium, which reduces the corrosion of the medium on the valve stem thread.
9.Self-adjusting Gap: There is a certain gap between the valve disc and the valve stem, which can be adjusted by itself and the seal is reliable.
10.Multiple Adjustment Functions: The valve disc can be processed into parabolic, spherical, needle-shaped, etc. according to customer requirements. It can play an adjustment (coarse adjustment) role on the pipeline.
11.Short Stroke Design: Short stroke, suitable for frequent opening applications.
12.Streamlined Flow Channel: Y-type stop valve-streamlined flow channel has a high flow coefficient, which can greatly reduce the pressure drop through the system.
13. ISO15848 FE A-level Sealing Standards: By improving the structural design and selecting a reasonable packing structure as well as qualified packing suppliers, the valve meets the ISO15848 FE A-level sealing test requirements to ensure the sealing performance of the valve under harsh conditions.
