With its field-replaceable sleeves and gate, the SKG Wafer offers hassle-free servicing, ensuring extended operational life and minimal downtime.

Built to withstand challenging operating environments, this valve is ideal for handling slurry, water, effluent, and other abrasive or corrosive media. Each unit is locally manufactured in South Africa, ensuring superior craftsmanship and availability of spares for ongoing support.

DFC’s commitment to innovation, quality, and durability is reflected in the SKG Wafer’s design. The valve’s bi-directional sealing, corrosion-resistant components, and versatile actuation options make it the perfect solution for industries requiring dependable shut-off performance and simplified maintenance routines.

Purpose-Built for Reliability and Efficiency

At DFC, our purpose is to solve typical and recurring valve challenges. We achieve this by manufacturing valves that offer the lowest total cost of ownership, highest reliability, and minimal lifetime maintenance requirements.

The SKG Wafer exemplifies this philosophy combining proven engineering principles with customer-focused design improvements. From water treatment and mining to pulp and paper or effluent control, this valve delivers performance consistency where it matters most.

Key
Features

Bi-Directional Flow and Shut-Off
The SKG Wafer ensures zero downstream leakage with its bi-directional flow and shut-off design, improving safety and operational reliability across process systems.
Field-Replaceable Sleeves and Gate
The heavy-duty elastomer sleeves and gate are easy to replace in the field, significantly reducing downtime and long-term maintenance costs.
Superior Flow Design
The absence of a seat cavity prevents unwanted solids from building up and interfering with gate closure, ensuring consistent operation even in slurry or abrasive media.
Enhanced Durability and Corrosion Resistance
No metal parts are in contact with the flowing media when the valve is fully open. This design feature extends service life and minimizes wear caused by corrosion or abrasion.
High Pressure Rating
Rated for 150 psi CWP (10 bar) pressure across all sizes, the SKG Wafer performs reliably in demanding applications.
Yoke and Spindle Protection
The dual-plate yoke design fully encloses the gate, spindle, and clevis, while the standard bellows protect the spindle against scoring from abrasive particles extending operational life and performance integrity.
Safety and Adaptability
Standard open and closed indicators, along with provisions for lockouts in both positions, improve on-site safety and ease of operation.
Actuation Versatility
The top bracket accommodates various actuation types for seamless conversion in the field, including:
- Hand Wheel

- Manual Gearbox

- Pneumatic Actuator

- Hydraulic Actuator

- Electric Actuator

Optional Accessories

For greater system integration, the SKG Wafer can be fitted with accessories such as proximity switches, solenoid valves, and junction boxes, providing monitoring and automation capabilities.

Technical Excellence and Local Manufacturing

Every SKG Wafer valve is produced with precision and attention to detail. The cast iron body, finished with a Fusion Bonded Epoxy (FBE) coating, ensures superior corrosion resistance and mechanical strength.

The lightweight yet robust construction enables easy installation and maintenance, while the valve’s compact wafer design saves space in systems where flange-to-flange length is limited.

Manufactured locally under stringent quality standards, the SKG Wafer aligns with DFC’s commitment to engineering excellence and sustainable production practices.

Applications

The SKG Wafer is suitable for a wide range of industrial applications, including:

Mining and Mineral Processing – Handles abrasive slurries with minimal wear.

Water and Wastewater Treatment – Ideal for regulating sludge, effluent, and reclaimed water.

Pulp and Paper Industry – Ensures clean shut-off in fibrous or particulate-rich media.

Power Generation and Chemical Processing – Offers corrosion-resistant operation in demanding systems.
