Product Overview
The KOZO CF8M Self-Cleaning Knife Gate Valve is designed for slurry, wastewater, pulp, mining and other solids-containing process services where a thin gate and open internal flow path help reduce material accumulation. The self-cleaning geometry is intended to limit buildup around the gate travel area during operation.
Key Design Features
- Knife-gate structure: Thin blade passes through slurry or fibrous media for isolation.
- Self-cleaning geometry: Designed to reduce solids accumulation around the gate path.
- CF8M stainless-steel body: Reference cast stainless construction for corrosive and wet process service.
- Large size range: Product family from DN50 to DN1000.
- Multiple actuation options: petunjuk, pneumatik, electric or hydraulic operation can be considered.

Seat and Blade Selection
Seat material and blade metallurgy should be selected according to abrasion, chemical compatibility, temperature and required leakage performance. The allowable temperature of an elastomer or polymer seat may be lower than that of the CF8M body.
Actuation Options
Pneumatic cylinders are often selected for frequent operation and remote control. Electric or hydraulic actuators can be supplied for large sizes or project-specific automation requirements. Limit switches, solenoid valves and filter regulators can be added as required.
How to Specify This Valve
Please provide DN, pressure rating, medium, solids content, particle size, body/blade/seat material, installation style, actuation, fail position and quantity.
Pertanyaan Umum
What makes a knife gate valve suitable for slurry?
The thin blade and open body geometry are designed to cut through or pass solids-containing media more effectively than many conventional gate-valve structures.
Can the valve be supplied pneumatically?
Ya. Pneumatic single- or double-acting cylinder arrangements can be selected according to size, required thrust and fail-action requirements.
