Product features:
1. To prevent abnormal pressure rise in the middle chamber, a pressure relief hole is set at the inlet side of the ram
2. Determine the top length of the bonnet according to the operating temperature of the valve, and ensure that the valve? Reliable sealing of packing
3. The materials of packing, gasket and other parts shall be selected reasonably according to the working temperature
4. Strictly control the chemical composition, low-temperature impact toughness and other mechanical properties of materials
5. Various piping flange standards and sealing surface types are adopted, which are suitable for various engineering needs
The opening and closing parts of stainless steel cryogenic gate valve are gate plates. The movement direction of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The two sealing surfaces of the most common mode gate valve form wedges, and the wedge angle varies with the valve parameters, usually 50. When the medium temperature is not high, it is 2 ° 52 ‘.
The gate of wedge gate valve can be made into a whole, which is called rigid gate; It can also be made into a ram that can produce slight deformation to improve its processability and compensate for the deviation of sealing surface angle during processing.
Packing of Standard Packing:
Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request. E FORUs’ is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
