Mizztech™ Class 150 Knife Gate Valves
Mizztech™ 15S and 15L series valves are a fully rated ASME Class 150 (PN20) guided shear gate designed for heavy duty applications.Designed specifically to handle heavy duty slurry applications, its innovative design, industry-leading performance, customisable features and absolute dependability havemade our Delta Industrial™ valves the knife gate valve of choice for multiple industries.
The bevelled edge gate design allows the knife gate to crush, cut, sever and expel solids that may be in the fluid stream. A precisely machined groove positions the elastomeric seat at the edge of the guided gate allowing the valve to seal equally well from either flow direction. The Mizztech™ knife gate valve provides 100% zero leakage. On discharge isolation, where the valve must seal tightly from either direction under varying pressure differentials, the Mizztech™ performs perfectly.

Product Features
- Solid stainless steel non-rising stem for excellent corrosion resistance and minimum clearance.
- Highly visible fluorescent coloured stem nut to verify position. Threads of nut coated with XYLAN to eliminate the need for stem lubrication.
- Heavy duty lockout pin for open and close position.
- LEXAN cover protects internal components and eliminates pinch points.
- Unique transverse seal design and scrapers deliver superior sealing even in high cycle applications.
- Bevelled edge gate to cut through tough solids.
- Fully guided gate eliminates gate movement during closing and eliminates gate deformation.
- Flush-out areas ensure product is expelled by the blade closing action.
- Mechanically retained seal prevents shifting during valve operation. Seal location and seat design ensure full bi-directional sealing and zero leakage.
