uncontrolled movements of the actuator in case of

normal flow, the poppet is held open by a spring with
enough force to counteract the force on the poppet
created by the flow.
the supply line is ruptured, the flow from 2 to 1
exceeds the specified flow rate, the P across the
poppet creates a force greater than the spring force
and closes the valve. This closing flow rate is adjustable.
The valve opens automatically by pressurizing connection
on the pressure P, the leakage rate through the valve
is approximately 0 to 6 in3 min. If this is excessive,
the valve threads can be sealed and made leak-free.

cartridge-type valve can be installed into an actuator
housing-type valve can be installed close to the actuator
or even directly into the actuator itself.
