MSS SP 81 Gate Valve
13 products found
An MSS SP-81 gate valve is a stainless steel, bonnetless knife gate valve manufactured and tested to the MSS SP-81 standard. Engineered for abrasive, high-viscosity slurries like paper pulp, mining mud, and sewage, it features a thin blade with a beveled edge that slices through suspended solids to prevent clogging. Because the compact body lacks a traditional bonnet, the cold working pressure is limited to 150 psi for sizes 2 to 24 inches and 100 psi for sizes 30 to 36 inches to prevent gate deformation. Conforming to this standard ensures full dimensional interchangeability when installing or replacing valves within standard ASME Class 150 flange lines. Procurement networks and industrial processing plants can eliminate slurry-line clogging and reduce pipeline downtime by importing certified MSS SP-81 knife gate valves directly from leading manufacturers in China via our advanced B2B commercial platform.
