At Braeco Sales, we work exclusively with GYLDT for our duckbill check valves, partnering with a manufacturer known for quality, innovation, and dependability.

Founded in 1989 and based in China, GYLDT is a trusted manufacturer of industrial valves and pipe fittings, offering an extensive product range that includes gate valves, butterfly valves, flap valves, dismantling joints, flange joints, rubber expansion joints, and pinch valves. GYLDT’s commitment to excellence is demonstrated through its advanced production facilities, skilled team, and internationally recognised certifications including ISO9001, Environmental Management System, and Occupational Health and Safety Management System.

While GYLDT produces a variety of valve types, duckbill check valves are a standout specialty—and the only GYLDT product line Braeco Sales sources. These precision-moulded, one-piece elastomeric valves provide reliable, maintenance-free backflow prevention, even in low-pressure environments. Their unique design allows forward flow with minimal head loss, while the flexible duckbill shape immediately seals to prevent reverse flow under backpressure.

GYLDT’s duckbill valves are:

• Constructed primarily of elastomer, reducing the risk of corrosion
• Designed with low cracking pressure (typically 1″–2″) for efficient flow
• Available in sizes from 15mm (½”) to 2400mm (96″)
• Custom-engineered to match specific operating conditions, including pressure and flow rates
• Enhanced with a curved bill for better sealing, even around debris

These valves are used in a wide variety of industries, from stormwater and wastewater management to industrial process systems, where low-maintenance, high-performance solutions are essential.

At Braeco, we rely on GYLDT’s proven quality and flexibility to deliver duckbill check valves tailored to each application. Whether you’re dealing with tidal outfalls, drainage systems, or corrosive environments, we can help you select or customise the right valve for the job.
