Expanded NSF 61 Certified Product Offering
leader in thermoplastic
61 certification of
its CPVC Type-21
ball valves and
CPVC ball check
valves in sizes
1/2" through 4”. Previously NSF certified Asahi/America
products include PVC ball, butterfly, gate, labcock and
ball check valves. The company’s Chem Proline®, Chem
Prolok®, Proline®, Pro150, Pro45 and Pro-Vent® industrial
piping systems, and PP-Pure® high purity piping
system are NSF 61-G certified.
Type-21 ball valves with CPVC bodies and EPDM or
FKM seats and seals, as well as ball check valves with
CPVC bodies and EPDM or FKM seats and seals meet
the requirements of NSF/ANSI/CAN Standard 61 –
Drinking Water Components.
Available with socket, threaded, or flanged (ANSI) end
connections, Asahi/America Type-21 ball valves are pressure
rated up to 230psi and are full vacuum rated in all
sizes. Double O-ring seals on the stem add protection,
and a tapered O-ring groove helps keep end connector
O-rings on the valve body during installation. With an
integrally molded ISO mounting pad, Type-21 ball valves
can be operated manually or actuated. An integrally
molded base pad allows valves to be mounted securely
or panel mounted. True union design allows for easier installation
and repairs, without expanding the pipe system.
The Type-21 ball valve blocks in two directions,
upstream and downstream, which leaves full pressure on
the opposite end of the valve.
Asahi/America ball check valves are true union in sizes
1/2" through 2" and single union in 3" through 4". The
solid thermoplastic ball is the only moving part, which
unseats to permit flow in one direction, but seals against
the seat to prevent backflow. Ball check valves may be
used vertically or horizontally, have a minimum shut-off
of 5psi, and all sizes rated for full vacuum service.
