Through Conduit Slab Type Gate Valve Camtech Through Conduit Gate valves offer increased value by incorporating advanced design features. These valves are designs and manufactured with a full bore port, rising stem, OS & Y type with floating seats. These valves are robust in construction and easy In-Line maintainability. The full port bi-directional flow capability minimizes pressure drop and turbulence. The valve seat faces are outside the flow stream and therefore the seats are protected from the erosive action of the fluid flow. These valves are piggable valves and Pigs and scrapers can be run through the valve without causing damage to the valve and seats.Get more news about through conduit gate valve,you can vist our website!
