Knife Edge Gate Valve

At Mcneil, we have a broad selection of knife gate valves made of different materials, in different sizes and with manual and automatic actuators to adapt to a myriad of fluid-control applications. The RBR-HC model is a wafer valve, for general use with fluids, although it is also appropriate for installations that conduct liquids laden with suspended solids. One-way valve (in two-way option) for assembly between DIN PN1 flanges.

Knife edge gate valve is engineered from finest quality components and under the strict supervision of expert quality controllers. These are available in various technical specifications and widely used in various industries for unobstructed flow of liquid or air. Engineered by implementing best available techniques, these products are widely acclaimed for high functional efficiency and longer service life. These are one of the most preferred selections of clients owing to its high tensile strength, robust design, longer functional life and precise design. These are compact in size and acclaimed for durability and rough and tough usage. Its OS & Y construction make these extensively efficient. These are extensively acclaimed for its corrosion resistance and uninterrupted performance. These are available in all standard sizes including 50 MM TO 600 MM. these are designed with MS SP 81 design standard and API 598, testing standard for flawlessness.
