FUNCTION
The Pressure relief valve DB06C is a
direct acting, spring loaded valve with
damped characteristics. Its job is to limit
the pressure in the system. The spring
acts with a certain force on the piston and
presses it on the valve seat. On the
opposite side the system pressure works
at port 1. If the hydraulic force is lower
than the spring pressure the valve
remains closed. Only if the force is higher,
the valve opens and the flow will be let to
port 2 (tank). If the system pressure is
equal to the spring pressure the valve
closes again.
Attention: Pressure at port 2 increases the
opening pressure! If ports are
interchanged or the pressure adjustment
is higher than the operating pressure, the
function of the valve is invalid.
