Product features of the duplex steel vacuum stop valve 2205-2507:
The product is designed and manufactured in accordance with the JB/T3595 standard, meeting the requirements for use in power station equipment.
The vacuum-sealed structure of the packing chamber ensures reliable isolation from vacuum.
The valve stem has good corrosion resistance, anti-abrasion and wear resistance.
The expansion coefficient is large, the gas tightness is good, and the system is reliably isolated from the atmosphere.
The vacuum isolation stop valve has parallel double sealing pairs and semi-forced bidirectional sealing. The sealing surfaces achieve zero leakage through the step-by-step action of the positioning movement and the wedge block's wedge tightening movement. It is suitable for the condenser and vacuum negative pressure system of thermal power plants, and serves the purpose of vacuum isolation and sealing.
The vacuum isolation stop valve features parallel double sealing pairs with semi-mandatory bidirectional sealing. The sealing surfaces achieve movement in place and the wedge-shaped blocks perform wedge compression movement in steps to achieve zero leakage. It is suitable for the condensation and vacuum negative pressure systems of thermal power plants, and serves the purpose of vacuum isolation and sealing.
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.
