Magnetic wafer non-return valve

This YGROS-MWNRV magnetic wafer non-return valve is based on the latest technology
available, this results introducing innovation and simplicity to the world of non-return/unidirectional
valves. The YGROS-MWNRV magnetic wafer non-return 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.

Working principle

The YGROS-MWNRV magnetic wafer non-return 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-
MWNRV magnetic wafer non-return 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-MWNRV magnetic wafer
non-return valve shutter offers a minimum resistance to the fluid, because it is far from the magnetic
field and therefore has a minimal closing force.
