MSS SP-81 Knife Gate Valve
5 products found
An MSS SP-81 knife gate valve is a linear-motion isolation valve manufactured, dimensioned, and tested in strict compliance with the Manufacturers Standardization Society (MSS) SP-81 standard for stainless steel, bonnetless knife gate valves. Featuring an ultra-slim, space-saving wafer body, it utilizes a precision-ground, knife-edged metal gate that slices cleanly through thick slurries, pulp stock, and solid-laden media to seal firmly against a resilient or metallic seat ring. The bonnetless, full-bore design eliminates internal body pockets where solids could accumulate, ensure zero fluid resistance when fully open, and minimize system weight. Wastewater treatment operators and pulp mill layout engineers can prevent solid-material clogging and minimize pipeline structural weight by importing certified MSS SP-81 knife gate valves directly from leading manufacturers in China via our advanced B2B digital marketplace.
