First, it is essential to distinguish between a gravity-fed silo discharge and a pneumatic conveying line. Specify the powder characteristics, particle size distribution, moisture content, differential pressure, operating cycles, and whether closing through a standing column of material is required. The valve selection must be based on a design fully engineered and proven for the application, not solely on line size.

Every system has its own demanding requirements.
ON-SITE AT YOUR FACILITY
From base materials to auxiliary systems.
Dry bulk powders, slurry-laden water, and compressed air systems each demand distinct engineering solutions. We analyze your equipment’s real-world operational requirements to guide the optimal selection.
01 / POWDERS & BULK SOLIDS
Reliable media isolation, engineered to withstand severe abrasion.
Cement, lime, fillers, and mineral fines: distinguishing between gravity flow and pneumatic conveying is essential. Particle size distribution, differential pressure, material build-up, and closure through standing columns of media all dictate valve technology selection. A standard water service valve is not inherently engineered for dry bulk powders.
02 / WASTEWATER AND SLURRY FLUIDS
Account for the media and suspended solids carried in the water.
Aggregate washing, recycled water, and settling sludge: specify solids concentration, particulate characteristics, and shutdown intervals. The valve bore, seats, and pump sealing systems must be evaluated as an integrated assembly.
03 / AIR AND THERMAL SERVICES
Also select ancillary process equipment.
Control air, cooling, and—depending on the facility—steam or thermal fluid: every system requires a dedicated selection. Steam is notably critical in manufacturing certain autoclaved materials. Gaskets, seals, and replacement parts are engineered specifically to match your operating conditions.
VAMECA SOLUTIONS
The right product family, followed by the right configuration.
These product families serve as starting points. Design, materials of construction, and operating limits must be validated for each specific service.
POWDERS, WATER, AND SLURRIES
Isolation Valves
Knife gate, butterfly, or ball valves: evaluate based on your media, application, and installation requirements. For powders and abrasive slurries, select an engineered design specifically built for demanding service.
Please specify: port configuration, solids handling, shut-off under differential pressure, and sealing direction.
WATER, AIR, AND STEAM
Utility Control and Regulation
Accurate flow or pressure control demands precise sizing. ARI STEVI control valves are engineered based on your specific media and the actual operating parameters of your auxiliary circuit.
To be specified: minimum and maximum flow rates, upstream and downstream pressures, and temperature.
PUMPS AND ROTATING EQUIPMENT
LATTY Compression Packings and Seals
Gland compression packing and mechanical seals are engineered for distinct installation requirements. When dealing with slurry or laden water, thoroughly evaluate the media, shaft specifications, and flush conditions before selecting the optimal sealing solution.
Please specify: equipment, section, speed, and sleeve condition.
BOLTED ASSEMBLIES
Flange Gaskets and Custom Cutting
Custom-cut flat gaskets and spiral-wound gaskets for your facility's piping systems. VAMECA fabricates precise geometries based on your drawings or dimensions and provides expert guidance on material selection.
Please specify: media, temperature, pressure, seating surfaces, and thickness.
Automating an Existing Valve
Torque or thrust, operating frequency, power supply, and position feedback: actuator mounting must be engineered alongside the valve. PS Automation expands your electric actuation possibilities.
PRIOR TO REPLACEMENT
The same diameter does not mean the same service application.
When planning a maintenance shutdown, connection interfaces and operating conditions are just as critical as the existing part number.
01
Materials and Operation
Dry powder, slurry, or clean fluid. Please specify solids, scaling, cycle frequency, operating temperature, and differential pressure.
02
Mounting and Dimensions
Diameter, flange standards, face-to-face dimensions, orientation, and operator access. A nameplate photo and a technical drawing streamline cross-referencing.
03
Control and Maintenance
Available power supply, control signal, fail-safe position, and clearance for removal. Please specify the scheduled turnaround date and anticipated wear parts.
