knife gates

STANDARD knife gate

The Montagnoli Standard Line Knife Gate Valves feature bidirectional operation and are designed to be used in a wide range of applications, handling pastes, pulps, powders, and granular materials such as cellulose, sludge, biomass, water, ashes, minerals, and various types of waste.

Their modular design allows for easy manufacturing in different materials and alloys, with actuators and automation accessories to meet a variety of process conditions. The Standard Line valves with Flex™ or Thermoplastic™ (Unique Technologie) bodies offer a high cost-benefit ratio and have a wider pH range for operation.

The standard face-to-face dimensions comply with MSS-SP-81, and the body fixing holes follow the ANSI 16.5 Class 150 or NBR 7675 PN10 standards.
