Crispin-Multiplex Mfg. Co. products

Crispin’s original Air & Vacuum Valves, the A and AL Series are designed to exhaust large quantities of air when filling pipelines, and to allow air to re-enter pipelines when draining to prevent collapse due to vacuum formation.

Combination Air Valves consist of Air and Vacuum Valves and a Pressure Valve mounted in a single body, providing the integrity of a single body casting while permitting each valve of the combination to operate as a separate unit.

The K-Flo 47 Series butterfly valve is a large diameter valve line designed for a variety of liquid and gaseous applications. Available in flanged connections thru 168”, and MJ connections thru 48”.

The K-Flo 500 series is a heavy-duty, resilient seated butterfly valve line for use in municipal, power and industrial applications. Tested for performance as well as seat and body leakage, all of the valves meet or exceed the latest AWWA C504 standards and requirements. Flanged ends are available on sizes 3” through 20”, while mechanical joints are available on sizes 6” thru 20”. Flanged x mechanical joint is currently available in 6″, 8″, 12″ and 16″ sizes.

The ES Series has an epoxy-retained seat configuration for KFlo large diameter butterfly valves. The seat provides full port flow equal to or greater than all major leading valve designs.

Mounted vertically or horizontally, these valves are designed to close before the pump stops, preventing flow reversal and eliminating water hammer and system surges. ANSI Class 150 & Class 300.

A versatile and cost-effective solution, Crispin’s Rubber Flapper Check Valve provides a smaller stroke then conventional swing check valves, reducing slamming while offering a strong and quick seal.

The SWC series provides an AWWA C-508 solution for more arduous check valve applications, including sewage and slurry. The substantial shaft diameter is ideal for difficult applications where back pressure can reach higher values quickly. Oil & Air Cushion configurations available.

Configurable to sizes large enough to handle any task, the 14″–108″ Double Disc Gate Valve series is a heavy-duty solution for flow control. Made from materials befitting their importance in a system, and backed by unrivaled service, L14 Series Valves can easily be operated in any position.

Our smaller sized Double Disc Gate Valve configuration, the 3″–12″ Series offers the same rugged reliability as our larger models at a competitive price, and in a compact package for small pipeline applications. Double Disc gate valves continue to be the most commonly used mechanisms for on/off service.
