The utility model discloses an ultra supercritical unit laminated membrane circulating valve which comprises a valve body. A valve cover is fixed at the top of the valve body. An electric actuator is fixed at the top of the valve cover. A valve base is arranged in the middle of the valve body. The top face of the valve base is attached with a sleeve. The top of the sleeve is fixedly connected with the valve cover. The sleeve is arranged on a valve clack in a sleeved mode. A padding pressing plate is fixed at the top of the valve clack. The top of the valve clack is connected with a valve rod. The top of the valve rod is connected with the electric actuator. A padding pressing cover is arranged on the valve rod in a sleeved mode. The padding pressing cover is fixedly connected with the top of the valve cover. Multiple laminated single membranes are arranged on the lower portion of the sleeve. Adjacent single membranes are attached tightly. Medium via holes are formed in the centers of the single membranes. Flow guiding grooves are evenly formed in the periphery direction of the single membranes. Pin via holes are symmetrically formed in the periphery direction along the single membranes. The flow guiding grooves comprise water inlets formed in the edges of the single membranes, water outlets connected with the medium via holes and flow channels between the water inlets and the water outlets. A plurality of corners are arranged on the flow channels. The angles of the corners are 90 degrees. The buffering effect of the valve is guaranteed through the multi-layer membranes, and valve sealing performance is good.
