PP NRV Nut Ball Flange

Component Description

PP (Polypropylene): This is the primary material of construction for the valve body and often internal components like the ball and ball ring. Polypropylene is chosen for its excellent resistance to corrosion and a wide range of chemicals, making it suitable for industrial and agricultural applications involving water, chemicals, and some solid media.
NRV (Non-Return Valve): Also known as a check valve, this is a two-port valve that automatically allows fluid (liquid or gaseous material) to flow in only one direction and prevents backflow without manual operation.
Flange: This refers to the type of end connection. The valve has flanges designed to be bolted to corresponding flanges on a pipeline or other equipment, ensuring a secure, leak-proof connection.
Nut & Bolt: The "nut bolt" part of the description indicates the method used to assemble the valve's body parts (e.g., top body and bottom body in a two-piece design) and to connect the valve to the pipeline flanges. The studs, nuts, and washers are typically made from a different material, such as stainless steel (SS) or mild steel (MS), for strength.
