Series ICV-125-2-2-T Cast Iron Wafer Check Valves are designed
for HVAC and general service applications. They are lighter, more
compact, utilize half the number of studs for installation and in some
sizes offer more flow capacity than conventional swing check valves.
The two spring-loaded plates close when the flow decreases,
without the necessity of reverse flow. The Series ICV-125-2-2-T is
designed and tested according to API 594 for use between ANSI
Class 125 or 150 flanges. The ICV-125-2-2-T features Lead Free*
construction to comply with Lead Free* installation requirements.
Features
• Lightweight & compact design
• Aluminum bronze disc plates
• EPDM seat bonded to body for leak tight sealing
• Silent check valve
• Complies with API 594
NOTICE
When installed in vertical pipe, flow direction in normal operation
should open discs, and inlet pressure should be greater than head
pressure.
Specifications
