Check Valve 80mm Brass Spring NRV
Description
The WSP 80mm brass variant belongs to the high-performance "E" Type configuration, specifically scaled up to handle the severe mechanical loads and backflow forces common in large-diameter piping systems. Features a solid brass plunger and body alongside a premium SS304 stainless steel spring to prevent internal corrosion and ensure instant mechanical sealing. Sealing Mechanics: Relies on an integrated NBR (Nitrile) seal to form a drop-tight bubble closure when back-pressure forces the disc against the valve seat. Rated for a maximum Cold Working Pressure (CWP) of 1600 kPa (PN16), making it highly robust for larger rural water transfers. Thermal Threshold: Explicitly rated to perform reliably at liquid operating temperatures reaching up to 80°C. Thread Profile: Cut with standard industrial Screwed BSP female threads conforming strictly to ISO 7-1 specifications for tight compatibility with standard Kiwi metallic or poly pipe fittings.
