	Item # CPJ-1-1/2, Series CPJ Jacket Check Valve

Quiet operation

Zero maintenance

Design prevents backflow

Will seal around solids

Designed to withstand wear

Tough enough for abrasive slurries

The Series CPJ Jacket Check Valve is designed to be efficient, quiet and tough. It requires no external power sources, thereby reducing operation costs. The valve's simple design means there are no moving mechanical parts to break down or jam, reducing maintenance costs.

CPJ Valves easily handle corrosive or abrasive materials such as raw sewage, sludges or slurries. Their flexible design allows solids to pass through unhindered and can even seal around solids trapped in the valve.

Series CPJ Jacket Check Valves are versatile and can be installed either horizontally or vertically. Drilling is available in all flange standards.

When placing your order, please indicate sleeve material by appending elastomer abbreviation (CR, NR, etc) to the model name. IE: Series CPJ-CR

The rugged full metal body and one-piece rubber valve combine quiet performance with lasting durability. The modular design of CPJ Series Valves allows them to fit easily into existing piping systems.

The heart of the Elasto-Valve Series CPJ Backflow Preventer is a fabric reinforced rubber "duckbill" sleeve manufactured with top quality materials. This flexible sleeve provides maximum flow with a minimum pressure drop across the valve at all times.

Unlike conventional check valves - which require frequent maintenance to replace worn seats, hinge pins, balls or flappers - there is little or no maintenance with CPJ Valves.

Available in a variety of styles and reinforced elastomers, the Elasto-Valve Series CPJ Backflow Preventer can be adapted to almost any application.

Elastomer Selection Guide

Ethylene Propylene Rubber (EPDM)
Most effective for applications involving water, steam or dilutedacids.

Viton™ (FKM)
Resists solvents, halogenated hydrocarbons, oxygen, weather,ozone, oils and chemicals.

Buna N (NBR)
Resistant to kerosene, moderate chemicals, fats, oils, grease andmany hydrocarbons.

Natural Rubber (NR)
Good abrasion resistance, tensile strength and resiliency. Alsosuitable when dealing with organic acids, alcohols, ketones andmost moderate chemicals.

Hypalon™ (CSM)
Resists strong acids and bases, ozone, weathering, heat andoxidizing chemicals.

Butyl (CIIR)
Good resistance to animal and vegetable fats, strong andoxidizing chemicals, oils, heat and greases.

Neoprene (CR)
Generally resistant to oil and grease, moderate chemicals, fats,many hydrocarbons and ozone. Resistant to barnacle growth.
