Relief Valve Manual Instructions Extract:

When starting or stopping swing operation, the swing circuit pressure becomes high. The relief valve prevents the circuit pressure from rising higher than the set pressure.
Low-Pressure Relief Operation (Shockless Function): 1. Pressure at port HP (swing circuit) is routed to oil chamber C (9) through orifice (2) in poppet (1).
2. Pressure oil in chamber C (9) flows to oil chamber A (8) through passage A (4) and flows to oil chamber B (7) through passage B (5).
3. As the pressure receiving area in oil chamber B (7) is larger than the pressure receiving area in oil chamber A (8), piston (6) moves to the left.
4. As long as piston (6) keeps moving, a pressure difference is developed between the front and rear of orifice (2) due to orifice (2). When this pressure difference is increased beyond the spring (3) force, poppet (1) is opened and pressure oil flows to port LP.
5. When piston (6) reaches the stroke end, the pressure difference between the front and rear of orifice (2) disappears and poppet (1) is closed.

High-Pressure Relief Operation (Overload Prevention):
1. After piston (6) reaches the stroke end, the circuit pressure becomes the normal relief set pressure.
2. When pressure at port HP increases further and is beyond the spring (3) set pressure, poppet (1) is opened and pressure oil flows to port LP.
3. When pressure at port HP is decreased to the specified level, poppet (1) is closed by the spring (3) force.
