I'm looking to procure 10 pieces of wafer-type butterfly valves suitable for a pneumatic conveying system specifically designed for roasted coffee beans. The valves should have a durable cast iron body paired with a stainless steel disc to ensure optimal functionality and resistance against wear. For sealing, please ensure the use of food-grade EPDM material. Additionally, manual lever operation is essential for ease of control. When you respond, please include a detailed quotation along with the unit weight, overall dimensions, and estimated lead time for the delivery. It's crucial that the specifications meet the requirements of our coffee conveying line to ensure seamless integration and performance. Looking forward to your prompt response!
