Size : 2" to 60" (50 mm to 1500 mm)

ASME Class : Class 150 and PN10

Design Standard : MSS SP 81

The Knife Gate Valve provides reliable shut-off in both dry and wet lines. The bonnet-less valve is equipped with a heavy-duty gate to cut through line fluids – and is ideally suited for abrasive slurries, pulp stock, semi-solids, dry ash, chips, etc.

The valves find application in paper and pulp, minerals and metals, steel plants, thermal power plants and chemical/ petrochemical industries. L&T Valves offers Knife Gate Valves in unidirectional and bidirectional configurations.

The versatile valves are offered with metallic/ resilient seats and push-through sleeves and are available in wafer, lugged and flanged constructions.

Salient Features:

Sharp heavy-duty knife-edge at the bottom of the gate cuts through solid sediments and ensures reliable shut-off

Gate offered with surface coatings based on customer demand - Hardfacing, Nitriding, Chrome-plating

Replaceable seats - Easy maintenance at site. Longer service life.
