ProFlex rubber check valves
710/730
STYLES
The PROCO Series 700
ProFlex
Rubber Check Valve is a cost effec-
tive way to control back pressures from sewage treatment plants,
outfalls and tidal operations. They are a fully passive flow device
requiring neither maintenance, outside sources of power or manual
assistance to operate.
The PROCO Series 700
ProFlex
Rubber Check Valves are offered as
direct replacements for ineffective and maintenance-ridden flap type
check valves, which are commonly known to seize, rust and bind in
unwanted positions. Unlike flap type valves, the
ProFlex
rubber check
valves will handle large obstructions without jamming or having swing
gates binding open. Specify the PROCO Series 700
ProFlex
Rubber
Check Valves to provide backflow protection from: (1) Sewage slur-
ries, (2) Outfalls to ocean fronts from heavy rainfall activity, (3) Pre-
vention from land erosion due to back flow conditions, (4) Protection
from saltwater to fresh water ponds or catch basins and numerous
other water based applications. Our history in the manufacture of rub-
ber piping products dates back to 1930. When an engineered solution
is needed to solve a piping or backflow problem, call PROCO.
The introduction of the PROCO Series 700
ProFlex
Rubber Check
Valves is the latest addition to the PROCO line, which has been spe-
cifically designed for the Water and Waste Water industry.
With current global awareness for clean water and the urgency to have all
water treatment plants operating under stricter standards, the PROCO Se-
ries 700
ProFlex
Rubber Check Valves will also be available in NSF61 ap-
proved Nitrile for all potable water and sewage applications. This will in-
clude water treatment plants, direct installation on potable water pump sys-
tems and other piping systems directly related to the potable water industry.
The PROCO Series 700
ProFlex
Rubber Check Valves are available in a
Flanged Type (Style 710), or a Sleeved Type (Style 730).
• Style 710 — Flanged Type:
Designed to bolt directly to existing
flanges or new installations, flanges are drilled 150# standard. Other
drilling standards such as: ANSI 250/300#, British Standard BS-10, JIS,
and DIN as well as square flanges are also available upon request. The
Style 710 can be installed in either a vertical or horizontal application.
• Style 730 — Sleeve Type:
Designed to easily slip over existing pipe
and affixed with heavy-duty Stainless Steel clamps. The Style 730 can
be installed in either a vertical or horizontal application.
Elastomers:
All of the PROCO Series 700
ProFlex
Rubber Check Valves
are available in a various selection of elastomers (see Table 1 below) and
back pressure capabilities to suit most applications.
The PROCO Series 700
ProFlex
Rubber Check Valves will not freeze or
deform and function solely on inlet and back pressures which will be present
in most applications.
Each valve is carefully constructed using the finest of engineered mate-
rials and built by the most experienced rubber technicians in the indus-
try. All check valves are engineered in precise detail to ensure proper
operation and will provide years of unhindered operation and trouble-
free service.
