• Slip-in Check Valve

• Prevents Backflow Inside the Pipe Line

• Eliminates Upstream Flooding

The In-Line CV slip-in check valve offers cost effective backflow prevention. Its low cracking pressure (1” to 2” above back pressure) combined with high-flow capacity (4x that of conventional slip-in duckbill valves) elimi-nates upstream flooding. Provides quick drainage during high flow conditions. The series In-Line CV slip-in check valve eliminates mechanical parts which can wear and jam in conventional check valves and can be in-stalled without modifications to existing structures.

Options:

• Sleeve Elastomer

• Back up Flange available for service at the end of pipe line

Performance Features:

• Low pressure drop

• Frost proof

• Silent operation

• Corrosion resistant

• Flanged Duckbill Check Valve

• Prevents Backflow at the End of a Pipe

The series DBF rubber check valve effectively ensures mono-directional flow of slurries, sewerage, sludge and other hard to handle fluids. The valve consists of an elastomer duckbill with a flanged connection. The back up flange is galvanized carbon steel, with 304 or 316 stainless steel as options. This simple rugged design eliminates the mechanical parts which can wear and jam in conventional check valves. They are available in a variety of elastomers.

Options:

• Sleeve Elastomer

• 316 Stainless steel pipe clamps

• Cast Iron Enclosure

The series DBMJ check valve effectively ensures mono-directional flow of slurries, sewerage, sludge and other hard to handle fluids. The valve consists of an elastomer duckbill type check valve inside an iron housing. This simple rugged design eliminates the mechanical parts which can wear and jam in conventional check valves. They are available in a variety of elastomer compounds, with a grey iron housing.

• Flanged Fully Enclosed Duckbill Check Valve

• Prevents Backflow Inside the Pipe Line

• Carbon Steel Fabricated Enclosure

The series DBMJ-F check valve effectively ensures mono-directional flow of slurries, sewerage, sludge and other hard to handle fluids. The valve consists of an elastomer duckbill type check valve inside a steel housing. This simple rugged design eliminates mechanical parts which can wear and jam in conventional check valves. They are available in a variety of elastomer compounds, with a carbon steel fabricated housing.

• Reverse Slip-In Duckbill Check Valve

• Prevents Backflow Inside the Pipe Line

The series DBRS slip-in check valve, like the series DBCP, offers a cost effective method of backflow prevention. It is designed for installation inside of a non-flanged pipe secured by expanding band clamp. The series DBRS slip-in check valve eliminates the mechanical parts which can wear and jam in conventional check valves.

Options:

• Sleeve Elastomer

• 316 Stainless steel expanding band clamp

Performance Features:

• Low pressure drop

• Frost proof

• Silent operation

• Corrosion resistant

• Flanged Inline Duckbill Check Valve

• Prevents Backflow Inside the Pipe Line

The series DBCP in-line check valve is a simple, reliable, cost effective method of backflow prevention. The series DBCP check valve is designed to be installed between two mating flanges. The simple maintenance-free elastomer with a flanged connection eliminates the mechanical parts which can wear and jam in conventional check valves. For installation at the end of pipe line, the valve can be ordered with optional back up flanges.
