China Clamp Duckbill Check Valve Suppliers

A Clamp Duckbill Check Valve is a versatile backflow prevention device combining the one-way flow control of a Duckbill Valve with the quick-connect convenience of clamp fittings, designed for flexible installation in diverse pipeline systems. Its structure features a lightweight metal or plastic housing enclosing a flexible elastomer duckbill sleeve (EPDM, nitrile, or PTFE), with clamp-style ends that secure to pipes using bolted clamps and gaskets for a tight seal.

The clamp connection eliminates welding or threading, enabling tool-based installation in minutes—ideal for systems requiring frequent disassembly, such as wastewater treatment plants or temporary pipelines. The clamp design accommodates minor pipe misalignments and simplifies maintenance, allowing easy removal for sleeve inspection or replacement without disrupting the entire system.

Like other Duckbill Valves, it operates without mechanical parts: forward flow pressure opens the duckbill’s slit for media passage, while reverse pressure collapses the slit to block backflow. This makes it highly resistant to clogging by solids, slurries, or debris, outperforming traditional check valves in dirty fluid applications.

Constructed with corrosion-resistant materials, stainless steel clamps suit industrial environments, while plastic variants work for low-pressure water systems. The elastomer sleeve withstands temperatures from -40°C to 120°C and resists chemicals, ensuring durability in harsh conditions.

In system integration, it pairs with components: Dresser Couplings for quick pipeline extensions, Rubber Expansion Joints to absorb vibrations, and Reducer Pipes for diameter transitions. Flange Adaptors can bridge clamp-to-flange connections, enhancing compatibility.

Key advantages include fast installation, clog resistance, and cost-effectiveness. The clamp design reduces labor costs, while the no-moving-parts structure minimizes maintenance. By combining flexible installation with reliable backflow prevention, it ensures efficient operation in municipal, industrial, and commercial fluid systems requiring adaptable, hassle-free non-return functionality.

Clamp Duckbill Check Valve

The clamp duckbill check valve is a device that connects the valve to the pipeline system by clamping. It is mainly used to prevent sewage backflow and protect the normal operation of the pipeline system. Its characteristics include easy installation, easy disassembly and easy maintenance, and it is particularly suitable for pipeline systems that need to be frequently disassembled. The clamp duckbill check valve is usually composed of a rubber valve body and a metal clamping ring. The rubber valve body has good elasticity and sealing properties and can adapt to various fluid media; the metal clamping ring is used to fix the rubber valve body to ensure its stable operation. The clamp duckbill check valve is widely used in pipeline systems that need to be frequently disassembled, such as temporary construction and frequent maintenance. Due to its easy installation and disassembly, it is particularly suitable for pipeline systems that need to be frequently replaced or maintained.

Product Detail

The clamp duckbill check valve consists of key parts such as the valve body, duckbill-shaped valve disc, clamping device, seals and other accessories. These components work together to ensure the stability and sealing performance of the clamped duckbill check valve in the pipeline system, while realizing the check function. In practical applications, the clamp duckbill check valve is widely used in various industrial fields due to its advantages such as easy installation, convenient disassembly and convenient maintenance.

The valve body is provided with a fluid channel inside, and the shape design conforms to the principle of fluid dynamics to reduce the resistance when the fluid passes. At the same time, a clamping mechanism is provided on the outside of the valve body to firmly connect the valve to the pipeline system.

When the fluid passes, the valve disc automatically opens under the action of the fluid pressure, allowing the fluid to pass smoothly; when the fluid stops flowing or flows back, the valve disc automatically closes under the action of its own gravity and fluid pressure, effectively preventing the fluid from flowing back.

The clamping mechanism is used to firmly connect the valve to the pipeline system to ensure that the valve will not loosen or fall off during operation. At the same time, the design of the clamping mechanism enables the valve to easily adapt to pipeline systems of different specifications without the need for complex installation tools.

VOICE

WHAT A CLIENT SAY?

Customers mentioned that the opening and closing process of the valve is very flexible, and it can automatically open and close according to the flow direction of the fluid. This helps to reduce the resistance and energy consumption of the fluid and improve the operating efficiency of the system. The design of the clamping mechanism allows the valve to easily adapt to pipeline systems of different specifications, improving installation efficiency. Compared with other types of check valves, the clamp duckbill check valve is more moderate in price and has a higher cost-effectiveness.

FAQ

Important things you should know

How to choose whether the duckbill valve clamp is built-in or external?

Duckbill valve with built-in clamp: suitable for occasions where it needs to be installed inside the pipeline, it can better integrate into the pipeline system and reduce the impact on the appearance of the pipeline. Duckbill valve with external clamp: suitable for occasions where it needs to be installed outside the pipeline, which is convenient for maintenance and inspection.

Material classification?

Carbon steel and stainless steel.

Why is it called a duckbill check valve?

Because it looks like a duckbill, it is called a duckbill check valve.

Uses of duckbill valves?

Generally used in wells, sewage pipes, reservoir docks, and sewage pipes.
