VEX1 Series Power Valve: Aluminum Material AC100V Rated Voltage 1.0MPA Pressure Regulator Valve

According to the balance between the acting force F1 of the pilot pressure (Port P1) on the upper side of the pressure regulating piston ③ and the acting force F2 of the pressure at Port 2(A) acting on the lower side of the piston through the feedback oil circuit, the poppet valve core ⑥ is closed. The pressure at Port 2(A) is set according to the pressure of P1, and the pressure at Port 2(A) forms a balanced structure, which slows down the pressure rise speed at the port (Figure [2]).

When the pressure at Port P1 rises and exceeds the pressure at Port 2(A), then F2 > F1, the pressure regulating piston moves upward, the upper poppet valve core opens, and exhausts from Port 2(A) to Port 3(P) (Figure [1]). The pressure at Port 2(A) drops to a certain value and returns to the state in Figure [2] again.

In addition, when the pressure at Port P1 is lower than the pressure at Port 2(A), then F1 > F2, the pressure regulating piston moves downward, the lower poppet valve core opens, and supplies air from Port 1(P) to Port 2(A) (see Figure [3]). When the pressure at Port 2(A) rises to a certain value, it returns to the state in Figure [2] again.
