ARVALV SDK Severe Duty

ARVALV® SDK Severe Service Knife Gate Valves are Class 1500 valves engineered for high-pressure, severe-duty applications including slurry and paste backfill systems. Designed for exceptional wear resistance and durability, SDK valves provide robust isolation and bi-directional drip-tight sealing. Conforming to MSS SP-151, they feature a unique transverse packing design and multiple Class 1500 drilling options.

Description

As mining operations pursue greater efficiency and sustainability, slurries are being transported over longer distances, at higher pressures, and with higher solids concentrations. This trend is especially clear in demanding applications such as paste backfill systems, where dense, abrasive materials must be pumped reliably into underground workings. In these environments, there is no room for compromise: valves must resist severe abrasion, maintain tight shut-off under high pressure, and deliver consistent performance in extreme conditions.

The ARVALV® SDK Class 1500 valve rises to this challenge. Engineered for high-pressure severe service, with exceptional resistance to wear, it delivers uncompromising performance where it matters most—providing robust isolation, exceptional durability, and long-term reliability in the toughest slurry and paste backfill systems.
