Industrial Valves and Butterfly Valves WAREX VALVE GmbH / WAREX VALVE

Wafer-type butterfly valves DKZ 103, DKZ 110, APS inflatable sealing valves, DBV ball valves, and DTS double-flap sluice systems by WAREX VALVE. Engineering equipment selection.

DKZ 103 Heavy-Duty Wafer Butterfly Valves

WAREX VALVE DKZ 103 heavy-duty wafer-type butterfly valves are engineered for demanding industrial processes. The valves ensure tight shut-off according to DIN EN 12266 Leak Rate A across DN 50 to DN 1200 at pressures up to 16 bar. One-piece bodies ensure high structural rigidity.

Nominal diameters DN 50 to DN 1200
Working pressure ratings up to 16 bar
Tight shut-off DIN EN 12266 Leak Rate A
Replaceable sealing sleeves and discs

DKZ 110 Lightweight Butterfly Valves for Bulk Solids

The DKZ 110 series is tailored for bulk materials, powders, and pneumatic conveying lines. Covering sizes from DN 50 to DN 600, the valves operate at pressures up to 10 bar in lightweight silumin or ductile iron bodies. Streamlined discs prevent media buildup.

Nominal diameters DN 50 to DN 600
Differential pressure up to 10 bar
Silumin and cast iron valve housings
Vulcanized or replaceable liner sleeves

DKZ APS Air-Pressure-Sealing Inflatable Valves

Patented Air-Pressure-Sealing technology inflates the sealing sleeve against the disc perimeter only after full closure. During opening and closing, the seal deflates, eliminating friction and abrasive wear. The valves offer long operational life in harsh dry powders.

Air-Pressure-Sealing APS technology
Friction-free disc positioning
ATEX compliance for zones 0 and 20
Replaceable inflatable sealing sleeves

DKZ 105 Silo and Container Butterfly Valves

The DKZ 105 series is specifically engineered for mounting beneath silo discharge cones, hoppers, and containers. Available in star-shaped SK configurations and full-flange VK designs, these valves provide dependable shut-off for granules, powders, and viscous media.

Star SK and full-flanged VK designs
Nominal sizes DN 150 to DN 300
Direct hopper and silo cone mounting
Hand levers, gearboxes and actuators

DTS Double-Flap Sluice Dosing Systems

DTS double-flap sluice systems are engineered for sealed discharging and dosing of bulk solids from cyclones, filters, and silos. Combining two butterfly valves with an intermediate chamber, they deliver reliable explosion decoupling and maintain system pressure boundaries.

Flange diameters DN 50 to DN 600
Chamber capacity from 0.5 to 300 liters
Dust explosion decoupling function
Pneumatic sequencing and purge valves

DBV Industrial Ball Valves for Powders and Liquids

WAREX DBV 400 and DBV 140 F industrial ball valves are designed for abrasive powders, pellets, and process fluids. Their full-bore cylindrical passage minimizes flow turbulence and pressure loss. Spring-energized PTFE and FKM seals deliver tight shut-off under fluctuating pressure.

Flanged connections up to DN 150
Operating pressure ratings to 16 bar
Full cylindrical bore design
Spring-energized PTFE and FKM seats

Replaceable Sleeves and Spare Components

We supply replaceable sealing sleeves in NBR, EPDM, FKM, PTFE, and silicone, valve discs, shafts, pneumatic actuators DZ, and overhaul kits for WAREX VALVE assemblies. Timely replacement of elastomer liners restores factory tightness and prevents unplanned plant shutdowns.

Elastomer sleeves in NBR, EPDM, FKM, PTFE
Valve discs in stainless steel 1.4408
Quarter-turn pneumatic rotary actuators DZ
Drive shafts, bearing bushes, and O-rings

Engineering Maintenance, Diagnostics and Overhaul

Standard maintenance protocols for WAREX VALVE assemblies require inspection of elastomer sleeves, verification of disc geometry, and checking shaft bearing clearances. Engineers perform on-site actuator calibration and hydrostatic pressure testing according to DIN EN 12266.

Wear inspection of liners and discs
Scheduled sleeve and seal replacement
Actuator stroke and limit switch setup
Pressure bench testing to DIN EN 12266

Selecting WAREX VALVE DKZ 103 and DKZ 110 Series for Bulk Materials and Industrial Fluids

The heavy-duty DKZ 103 series is engineered for demanding industrial processes with differential pressures up to 16 bar and diameters from DN 50 to DN 1200. Its one-piece housing ensures rigid piping alignment.

For pneumatic conveying and powder hoppers with pressures up to 10 bar, the lightweight DKZ 110 series provides streamlined flow and low operational weight.

Implementing DTS Double-Flap Systems and DBV Full-Bore Ball Valves in Powder Handling

DTS double-flap sluice systems deliver reliable pressure-neutral dosing of bulk solids from filters and silos, providing robust explosion decoupling.

For abrasive slurries, powders, and aggressive fluids requiring full cylindrical bore passages, WAREX supplies DBV industrial ball valves with spring-energized seats.
