Ball valve / metallic - Valbart Subsea
The Valbart Subsea Trunnion-Mounted Ball Valve uses metal-to-metal seats to make it work in more situations while using a tungsten carbide coating with a ball and seat setup. This uses elastomeric or lip seaps to keep the insides from leaking. This has seals that can resist corrosion and nickel alloys are especially used to help keep sulphide and chlorine stresses from making things worse. It uses self-relieving seats and works with double piston effect seats and uses two ball and seat seals to make it functional. This is made to make everything run as safely and under control as possible.
