API 6D Slab Gate Valve
- 双恒
- China
Main features: Slab gate valve is an efficient and reliable through-conduit gate valve, with two floating seats to provide a tight seal with the gate. Full bore through conduit design can eliminate flow turbulence. Pressure drop is no larger than through an equal length of pipe.
