API 6D Through Conduit High Pressure Self-tightening Slab Expanding Gate Valve For Natural Gas
TEKO INDUSTRY produces a full range of through conduit gate valves for production, processing and transmission applications.
Through conduit gate valves provides superior bubble tight sealing capabilities in gas services and unmatched robustness in harsh services with high pressure, high temperature and sand service.
Our through conduit gate valve comply with the following standards:
-Double block and bleed, double isolation
-Soft or metal seated
-Low temperature carbon steel
-Stainless austenitic and superaustenitic
-Nickel Super Alloy
Double Block & Bleed
When the valve is at closed position, and with equal or no pressure, both spring loaded seats can shut off the line pressure independently from both upstream and downstream sides. Thus blocking both sides and the body cavity can be bleed out by opening the drain plug. This creates a DBB Double Block & Bleed scenario.
