TOPMOST Full welded ball valve(regular bore butt welded ball valve)Configuration:Valve makes up of full welded ball valve body and teflon seal. Under the impact of impurity and chemistry, it can word long life. Skiving elaborateStainless steel ball can ensure open and close freely. Adopting floating ball structure, Hardened steel for springs manufacturing. Bevel washer makes seal pressing on ball tightly. Even when the pressure is not stable. Valve can be compactness.Peculiarity:1).No need for maintenance,adjustment and lubrication. It's easy fixing. It's works safely and long-term under low cost.2).We can do longer valve stem, it helps keeping warm.3).Operation handle can be dismantled and fixed on other side.4).Valve body doesn't contain heaviness and fallibility casting.5).It's very easy for fixed adjustable structure.
