Crispin Product Families

Air Valves

With countless years of experience in Air Valves, as we hold the the first US patent for them, we provide many different lines across potable and wastewater to suit any project. Rugged, reliable, and attached to world-class service, no one does Air Valves better.

Check Valves

We also offer various types of Check Valves, such as Rubber Flapper, Swing, Tilting Disc, and Silent Checks. Coming with our standard Crispin quality and service, all our check valves are optimized for minimal head loss and maximum efficiency in flow reversal.

Butterfly Valves

Added to the Crispin name in 2005 after aquiring the KFLO line, our Butterfly Valves have become know across the industry and world for their quality. All valves meet or go beyond AWWA C504 standards, after being extenisvely tested on-site.

Plug Valves

Introduced in 2012, our long-lasting Eccentric Plug Valves have been used anywhere that the pumped contents can contain fouling or abrasive solids. Simple – yet critical.

Gate Valves

Our newest product line, Ludlow-Rensselaer Gate Valves, was recently acquired from Patterson Pump. We are pleased to now offer our customers Double Disc and Resilient Wedge Gate Valves backed by the unmatched combined experience of Crispin and Ludlow-Rensselaer.
