Brief introduction:

YF type overflow valve adopts balanced piston type structure, and the pressure is adjusted by hand.It works stably and has the characteristics of high pressure and low noise.In the hydraulic system, the overflow valve is an indispensable important component, the main function is to maintain the pressure of the hydraulic system nearly constant or prevent the system pressure overload, play a safety role.

1. The valve of this system can operate under pressure ≤31.5MPa at normal operating environment temperature ·20℃ to +65℃ : working medium no. 20 or no. 30 hydraulic oil, etc. The normal oil temperature is 50℃±5℃, the kinematic viscosity is 17-32 centistoke, and the filtration accuracy shall not be less than 30 microns.

2. For easy operation, the valve cover connected with screw thread and flange can be installed at four 90° positions, and the plate connection can be installed at three 90° positions

3. The pressure regulating hand wheel of zhenhai capsule accumulator factory can change the valve's regulating pressure. The pressure increases with right rotation and decreases with left rotation.

Iv. As remote control, when high and low pressure multi-stage control or unloading, the remote control port m18x1.5 screw plug can be screwed off, and the capsule accumulator factory of beilun is connected to the control oil circuit.

This series valve P port for oil inlet, 0 port for oil spill, K port for external control
