A seal with a wedging element for adjustably compressing the seal. The seal abuts a surface, such as a gate of a gate valve, to seal against the surface with a sealing force that prevents fluid flow therebetween. The sealing force of the seal may be increasing or decreasing compression by adjusting the wedging mechanism. For example, as the seal wears away due to friction between the seal and a sliding gate, the compression may be increased in the wedging mechanism to increase the sealing force to a low threshold.

A gate valve for controlling flow of a fluid therethrough is provided. The gate valve includes a valve body having an outer surface, a bore, a valve cavity, a first seat pocket, a second seat pocket, and first and second fluid ports extending from the outer surface to the first and second seat pockets, respectively. First and second seats are positioned respectively within the first and second seat pockets. The seats include circumferential fluid channels and one or more conduits in fluid communication with the fluid ports for permitting a repair fluid to be injected into the ports to the faces of the seats. A gate is slidably positioned within the valve cavity between the first seat and the second seat for controlling flow of a fluid through the valve. Sand shields are also provided at the rear of the seats to capture particulates and to bias the seats against the gate.

A low-profile and small-size valve to a shut off a flow of fluid in a pipeline includes a frame, a tube, a moving part, a lever, an elastic part, a latch, and a trigger. The tube is movable with the moving part. The lever is rotatable around an axis. The elastic part can push the lever to rotate after the trigger pushes the buckle away from the lever to unlatch the lever and allow rotation. During the rotation of the lever, the lever pulls on the moving part, and the moving part pulls on the tube together to disconnect the tube from the pipe. The valve improves the convenience and efficiency of shutting off a flow of fluid. A pipeline and an immersion cooling system is also disclosed.
