Gate Valve
Gate Valve is divided into slab gate and split gate valve. Slab gate valve include FC and FLS type. Split gate valve is called expanding gate valve who seal the valve by push split gate. Expanding gate valve is normally work under 5,000 psi. but FC & FLS type gate valve can work from 2,000psi to 20,000psi.
Gate Valve is also can divided into rising stem and non-rising stem gate valve. If it is rising stem gate valve, normally there is balance stem at the bottom of body.
If bore size reaches 7-1/16", we can choose ball screw gate valve which reduce operate torque. Ball screw gate valve belong to rising stem gate valve.
