Magnetic non-return check valve
This YGROS-SRCVM magnetic non-return check valve is based on the latest technology available,
this results introducing innovation and simplicity to the world of non-return/unidirectional valves. The
magnetic non-return check valve design is based on the principle of an external magnetic field to
interrupt the backflow inside a tube by means of a shutter. This innovative idea guarantees a level of
sterility and cleanability which no other classic spring check valve can offer. As a matter of fact,
using a check valve which excludes and completely substitutes the use of the classic spring and as a
result any contact with the process fluids, so total cleanability is guaranteed by design.
Technical features
The differential pressure required to open the check valve in a horizontal position is 0.05 bar; this
differential pressure tends to zero when the check valve is open and therefore operational losses of
energy are almost zero.
Working principle
The YGROS-SRCVM magnetic non-return check valve opens when the inflow pressure exceeds
the outflow and the magnetic field pressure combined. The valve closes when the difference in
pressure ceases, and a higher backpressure pushes the check valve shutter against the seal.
The major difference between a traditional spring check valve and the innovative YGROS-SRCVM
magnetic non-return check valve is in the very low resistance and delta pressure generated by the
shutter into the line.
While a traditional spring valve when open, offers the maximum resistance to the fluid, because the
spring is at maximum compression, the YGROS-SRCVM magnetic non-return check valve shutter
offers a minimum resistance to the fluid, because it is far from the magnetic field and therefore has a
minimal closing force.
