In summary, our Gear Box DN400 PN25 RF Flange Fully Welded Ball Valve With Extended Stem is a professional-grade valve that offers exceptional performance, durability, and reliability. Its advanced features and adherence to industry standards make it the ideal choice for various applications.
Features:
First, wear-resistant; because the spool of the hard seal ball valve is alloy steel spray welding, the seal ring is alloy steel surfacing, so the hard seal ball valve will not produce too much wear and tear when switching. (Its hardness coefficient is 65-70):
Second, the sealing performance is good; because the seal of hard seal ball valve is manually ground until the spool and the seal ring completely match before use. So his sealing performance is reliable.
Third, the switch is light; because the hard seal ball valve sealing ring at the bottom of the spring so that the sealing ring and the spool held tightly together, so in the outside world force exceeds the spring preload switch is very light.
Fourth, long service life: has been widely used in petroleum, chemical, power generation, paper, atomic energy, aviation, rockets and other departments, as well as people's daily life.
What it is Fully Welded Ball Valve:
An fully-welded trunnion valve is a type of ball valve used to control the flow of gases or liquids through a passageway. It is different from other ball valves because its ball is mounted and welded to a trunnion at the bottom and supported by a stem at the top. All other parts are also connected by welded joints.
Fully welded ball valves are used in extreme working conditions such as natural gas, city heating, long-distance pipelines, etc. Fully welded ball valves are restrained over the entire cross-section to overcome higher loads. Therefore, stress corrosion cracking and external contamination can be actively avoided to extend the service life of the valve.As the valve seat is composed of carbonized Teflon sealing ring and disc spring, it has strong adaptability to pressure and temperature changes and will not produce any leakage slip in the marked pressure and temperature range.
Fully Welded Ball Valve Applications
Fully Welded Ball Valves for the Petrochemical Industry:
Welded ball valves can be used to control the flow of petroleum products in refinery feed stock lines to avoid contamination of separate product lines.
Fully Welded Ball Valves in Chemical Manufacturing:
Due to their tight sealing characteristics, trunnion ball valves are ideally suited for the safe management of corrosive chemicals after production.
Fully-welded ball valves for emergency shutdown:
Operate quickly and provide a full seal to prevent media flow, making them suitable for emergency system shutdown applications.
Fully-Welded Ball Valves for Power Generation:
Controlling power generation must also control fuel. Trunnion ball valves control gas and liquid fuel flow very precisely.
