RESILIENT WEDGE VALVE

In 1975, Clow recognized the increased requirements and
escalating maintenance cost of water systems in the
United States.

Clow responded by introducing the first R/W (Resilient
Wedge) Valve in America. This introduction revolutionized
the valve market in the U.S.

Clow was the first to introduce, and still leads in the design
and technical development, of the bubble-tight resilient
seating valve.

The Clow Resilient Wedge Valve, with its unique features and
benefits, were the first to be manufactured with both AWWA
and UL/FM approval for all water system requirements.
