Valve operation
How it works — The compressor descends onto the diaphragm, pressing it against the body to achieve a complete drip‑tight seal. Reversing the motion lifts the diaphragm for unrestricted full bore flow. All moving parts remain isolated above the diaphragm, ensuring long life with abrasive slurries.

Sludge & abrasive slurry
Full bore eliminates clogging, ideal for wastewater, mining tailings.
Dry media handling
Powders, cement, soda ash — tight shut-off and abrasion resistant linings.
Low maintenance
All moving parts isolated, quick diaphragm change without removing valve body.
