LGF type ball valve

This ball valve is made according to API 6D Standard, with trunnion mounted ball for medium and high pressures. The body is made of 2 or 3 forged steel parts. The seat rings loaded helical springs, resulting in high safety closure even at low pressure. At the standard version design the ball and the seat rings are supplied with nickel coating, but there is a version with metal closing, tungsten-carbide coating designs as well. All ball valve are antistatic.
