Several types of Check Valves:

RF-Series_Crispin Check Valve

               RF-Series ASR Crispin Check Valve

Most notably, Crispin also builds a Rubber Flapper Check valve. They include an option for adjustable spring return for the fast closing check valve, Model No. RF-ASR. The Crispin RF-ASR is an upgraded Surge Valve.

Extremely cost effective and simple in design, the “ASR” attachment substantially increases the closing speed of the standard “RF” check valve, thus reducing water hammer.

The adjustable configuration employs the same simple flat spring, but also includes an Externally Adjustable Tension Screw for setting spring preload.

The “ASR” can give you true adjustability without having to remove the top cover and place additional springs against the disc.

The K-Flo series Plug valves with 100% Full Port in full compliance with AWWA C517 for use in municipal, power and industrial applications. 

Butterfly Valves feature field-replaceable seats. Our heavy duty butterfly valve line in full compliance with AWWA C504 and range from 3″ to 168″ for use in municipal, power and industrial applications.
