The primary difference is in the installation method. A **Wafer type** valve is clamped between two pipe flanges by long bolts that run from one flange to the other. A **Lug type** valve has threaded “lugs” or holes on its body that align with the bolt holes on the pipe flanges, allowing it to be bolted directly to one flange. This makes Lug type valves suitable for dead-end service where one side of the piping can be removed for maintenance while the valve remains in place. ### Q2: Your valves are certified to API 6D. Do they also meet API 609 standards for butterfly valves? Yes, our design and manufacturing philosophy is guided by the industry’s most stringent standards. While our **API 6D certification** primarily covers pipeline valves, our butterfly valves are designed and manufactured in accordance with **API 609** standards for dimensions, materials, and testing. ### Q3: What is your typical delivery time for a project-scale order (e.g., 100+ pieces)? Our key advantage is speed and reliability, a major concern for many clients. Thanks to our efficient production system and large capacity (over 3000 tons annually) , we can deliver most standard product orders, including project-scale quantities, **within 20 days.**For custom orders, we will confirm the delivery schedule when we provide the quote. ### Q4: Can I order valves with our company's branding (OEM) or specific material requirements? Absolutely. We offer full OEM/ODM services. We can customize the valve nameplate with your brand logo and provide valves in specific materials to meet your process requirements(). This is a core service we provide for our distributor and EPC partners. ## Get a Custom Quote in 24 Hours!
