The Nil-Cor
Advanced Composite Ball Check Valve joins our line-up of
Ball and Butterfly valves to make an all-FRP piping
system a reality. No more worries about supporting heavy
alloy or lined ductile iron valves. And with total
through-body corrosion protection, no more worries about
failed liners and perforated bodies. Nil-Cor check valves
are virtually unaffected by the harshest external
environments including ultra-violet exposure
Nil-Cor check valves have
been designed to achieve strengths equivalent to metals
with the inherent corrosion resistance of advanced
polymer matrix composite materials. The exceptional valve
body strength and operational integrity of Nil-Cor
composite valves are achieved through both material
properties and valve design. To give ruggedness and
durability, our composite check valve has a body designed
with heavier wall and flange thickness than metal or
plastic valves. This engineered approach results in
design factors similar to those practiced with metal
valves and your assurance of absolute safety.
Our ball check design has
four internal ball guides molded right into the body.
This delivers exceptionally secure ball support and
smooth operation in even dirty fluids. As a bonus, this
construction reduces the number of parts in the valve for
simpler and less costly maintenance.
Viton seats and a solid
PTFE ball combine to deliver bubble-tight shutoff and low
reseating pressure drops. The valves may be installed in
horizontal as well as vertical lines. A convenient raised
cast-in arrow on the body shows the correct installation
direction.
