The YF-S type relief valve adopts a balanced piston mechanism and the pressure adjustment is via a handwheel. It is reliable in operation, stable in performance, and has the advantages of small size, light weight, easy maintenance, and low noise. It is an important component in hydraulic systems, capable of making the pressure set by the system close to constant or preventing the system pressure from exceeding the limit, thus providing a safety function. 

1. This series of valves can operate normally within a pressure range of

a. The valve cover with threaded connection and flange connection can be installed at any 90° position around the periphery, and the plate-type connection can be installed at three 90° positions arbitrarily. 

b. The rotating pressure adjustment handwheel can change the set pressure of the valve. When turned counterclockwise, the pressure increases; when turned clockwise, the pressure decreases. By replacing the spring, different pressure adjustment ranges can be achieved. 

c. When used as remote control, multi-level control of high and low pressure, or for load control, the M18x1.5 screw on the remote control port can be unscrewed and connected to the control oil circuit. 

d. For this series of valves, the P port is the inlet port, the O port is the overflow port, and the K port is the external control port.
