Q11H three-stage forging hard sealed ball valve with internaHard sealed ball valve with internal threadl thread

Q11H three-stage forging hard sealed internal thread ball valve adopts metal to metal sealing pair, that is, metal sealed ball valve, which is characterized by the ball and the valve body are made of high temperature resistant metal materials, and the seat is made of metal or heat resistant alloy (such as cobalt chromium tungsten carbide, etc.). The applicable temperature range is wide, and the thermal expansion coefficients of various metal materials are not different, as long as they are properly selected, they can be basically consistent, which is conducive to coordinating temperature difference deformation.

Q11H three-stage forging hard seal internal thread ball valve design features:

1. The movable metal valve structure with plate spring preload has reasonable sealing force design, flexible opening and closing, and reliable sealing.

2. According to the needs of users, it can be designed to be suitable for the structure of the medium including valve body particles, materials and other structures resistant to higher temperatures.

3. Adopt bottom-mounted valve holder and set up reverse sealing structure to ensure reliable sealing at the packing place.

Product working principle:

one The internal thread hard sealed ball valve adopts metal to metal sealing pair, that is, metal sealed ball valve. The ball surface adopts advanced spraying technology. Through the treatment of various working conditions, the highest hardness of the sealing surface of the seat can reach HRC72.

2. The metal seat ring is in contact with the sphere and is sealed with the sphere by a uniform spring load acting on the seat ring. At the same time, due to the action of the spring load, the auxiliary seal expands to realize the seal between the valve body and the seat. The load of the spring is sufficient to provide a reliable seal between the seat and the ball, especially under low pressure conditions

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.
