All oil ports, safety valves, and one-way valves are
centrally arranged on the valve body, with a compact structure for
easy pipeline layout.The safety valve adopts a pilot type
structure, with good opening and closing characteristics, and can
reduce the heat loss caused by large flow overflow.The circuit is
equipped with a bridge pressure interface, which can serve as an
oil source for subsequent hydraulic actuators.Control method:
pneumatic control.The valve body is made of high-quality RuT400,
and the valve core is made of 40Cr quenched and tempered hard
chromium plating process, with small deformation and corrosion
