External o-ring seal provides sealing between the
check valve cartridge and the mating cavity into
which it is inserted.
Center stem guidance optimizes the return of
the plunger head into its seat for effective
sealing and to prevent jamming even in hard
water conditions (water with high mineral
content or sediments)
Standard XHnotion check valves are spring
loaded to ensure reliable operation in any
position of installation and fast positive sealing
even in low backpressure conditions.
