A gate valve, also known as a sluice valve. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened. Gate valves are widely used for all types of applications and are suitable for both above-ground and underground installation.
Gate valves are designed for fully open or fully closed service. They are installed in pipelines as isolating valves, and should not be used as control or regulating valves. Operation of a gate valve is performed doing an either clockwise to close (CTC) or clockwise to open (CTO) rotating motion of the stem. When operating the valve stem, the gate moves up- or downwards on the threaded part of the stem.
Resilient seat gate valves are gate valves with an elastomer lined wedge. Resilient Seated Gate Valve are approximately 50% less weight than conventional cast iron valves . Most durable due to inherently corrosion-resistant and encapsulated EPDM ductile iron wedge
