DAY type stacked hydraulic control one-way valveDetailed product description：

DAY type one-way valve is a pilot operated one-way valve with a stacked structure. This series of valves can maintain good sealing performance at one or two working oil ports without leakage even under long-term pressure holding. When the pressure oil flows freely from A to A1 or from B to B1, it stops in the opposite direction. When the directional control valve is in the neutral position in the hydraulic system, in order to reverse the flow of oil through the one-way valve, it is necessary to open the one-way valve with the help of control oil.
