I am looking for a PVC butterfly valve with a specific size and pressure rating. Please provide me with details regarding the technical specifications, including dimensions, pressure resistance, and any applicable standards or certifications. I'd also appreciate information on the materials used in the valve's construction to ensure it meets the necessary quality requirements for my project. Additionally, I would like to know your pricing structure, including any bulk purchase discounts, and the estimated lead time for delivery. Please also inform me about your warranty and return policy. If you have a product catalog or datasheet, that would be great. Looking forward to your prompt response so that we can move forward efficiently!
