How about FRPP WEIR FLANGED DIAPHRAGM VALVE

FRPP stands for Fiberglass Reinforced Plastic Pipe, which is a type of piping material that is made from fiberglass reinforced plastic. A flanged diaphragm valve is a type of valve that uses a flexible diaphragm to control the flow of fluid through the valve. The diaphragm is located between the valve body and the valve bonnet, and it is connected to a stem that is used to actuate the valve. The valve body and bonnet are connected by a flange, which allows the valve to be securely attached to the piping system. Flanged diaphragm valves are typically used in a variety of industrial applications, including water treatment, chemical processing, and food and beverage processing. They are known for their durability, corrosion resistance, and ability to handle high pressure and temperature.
