For over 170 years, one name has stood as a pillar of American industrial innovation: Crane Company. From supplying essential components for the transcontinental railroad to providing pumps that landed on the moon, Crane’s legacy is built on engineering excellence. Within this world of sophisticated flow control systems, the simple yet ingenious Duckbill valve plays a vital, behind-the-scenes role in ensuring system integrity, preventing backflow, and maintaining operational safety across countless industrial applications.
This blog post explores the rich history of this American manufacturing icon and delves into the essential function of the Duckbill valve within its comprehensive product portfolio, particularly through its globally respected Crane ChemPharma & Energy business.
A Legacy Forged in Integrity: The Crane Story
The story of Crane Company is a classic American industrial narrative, founded on July 4, 1855, when a young Richard Teller Crane established the R.T. Crane Brass & Bell Foundry in Chicago . From the very beginning, Crane built his company on a foundation of unwavering ethics. On the day he founded the business, he wrote a personal resolution that still guides the company today: “I am resolved to conduct my business in the strictest honesty and fairness; to avoid all deception and trickery; to deal fairly with both customers and competitors; to be liberal and just toward employees and to put my whole mind upon the business” .
This commitment to integrity and quality propelled Crane to the forefront of industrial America. By the 1880s, the company operated four manufacturing facilities and employed over 1,500 people . In 1890, R.T. Crane established a metallurgical laboratory, probably the first in the Midwest, ensuring Crane products had the strength to meet ever-higher fluid pressures and temperatures . In 1936, the company was listed on the New York Stock Exchange .
Over the decades, Crane’s engineering prowess expanded through strategic acquisitions, including Chapman Valve, Cochrane Corporation, and Chempump, solidifying its position in fluid handling . A pinnacle moment came in 1969 when Crane pumps were used in the Gemini and Apollo space programs—truly putting Crane technology on the moon .
Today, Crane Company is a diversified manufacturer of highly engineered industrial products, headquartered in Stamford, Connecticut . With over 8,500 associates worldwide, the company generated record financial results in 2025, with earnings per share up 23% . Its Process Flow Technologies segment, which includes Crane ChemPharma & Energy, provides mission-critical flow control solutions to customers in the chemical processing, oil & gas, refining, power generation, and pharmaceutical industries .
The Duckbill Valve: A Simple Solution for Critical Challenges
The Duckbill valve is an elegantly simple check valve, typically made from flexible elastomers like rubber, EPDM, or specialized polymers. Its unique, beak-like shape allows fluid or gas to flow freely in one direction under pressure. When forward flow stops or attempts to reverse, the flexible material instantly snaps shut, creating a positive seal that prevents any backflow. This self-actuating, automatic function requires no external power or moving parts, making it inherently reliable and maintenance-free in demanding environments.
Within Crane’s vast portfolio, the Duckbill valve principle is most directly applied in their line of specialized check valves, including the patented Duo-Chek® and Noz-Chek® non-slam check valves, as well as in various diaphragm pump components .
Key Product Lines Featuring Check Valve Technology
Crane ChemPharma & Energy, a business unit within Crane’s Process Flow Technologies segment, designs and manufactures a comprehensive range of high-performance products . The following product families are most relevant to Duckbill valve applications:
Key Application Scenarios
Within Crane’s diverse industrial markets, Duckbill-style check valves are critical components in the following areas :
- Chemical Processing & Pharmaceuticals: In plants handling corrosive, toxic, or high-purity fluids, preventing backflow is paramount. Crane’s Saunders® diaphragm valves and Resistoflex® lined valves are used in dosing skids, bioreactors, and transfer lines to ensure fluid integrity and protect upstream equipment .
- Oil & Gas and Refining: In refineries and petrochemical facilities, non-slam check valves like Duo-Chek® prevent damaging pressure surges and backflow in pipelines, compressor stations, and processing units .
- Power Generation: Crane provides valves for nuclear and conventional power plants, where reliable check valves are essential for cooling water systems, steam cycles, and safety-related services .
- Water & Wastewater Treatment: In municipal and industrial water treatment, check valves prevent reverse flow in pump discharge lines and chemical feed systems, maintaining system pressure and preventing contamination.
