Industrial valves for critical applications
Flowrates designs, configures and distributes industrial valves for the most demanding environments: energy, chemical, heavy industry. From engineering to after-sales support, with flawless traceability.
Flowrates supports industrial companies and distributors in the water, energy, chemical and heavy industry sectors.
Making industrial valve expertise accessible to those who keep industry running.
Flowrates supports players in the energy, water, chemical, food & beverage and heavy industry sectors in mastering their flow control needs, with recognised expertise in butterfly valves, knife gate valves and fluid control solutions for demanding industrial applications.
Whether the requirement is standard or critical, our teams analyse the actual process constraints.
Temperature, pressure, corrosion, abrasion, sealing performance, operating frequency or regulatory requirements: every parameter is factored in to select the most suitable technology, materials and configuration.
Accustomed to the most demanding environments, we apply that same level of rigour to our clients’ everyday needs, to guarantee the reliability, performance and long-term integrity of their installations.
The valve is chosen from the process. Not the other way around.
Our Industrial Valve Solutions:
Standard and Custom
In industrial valves, our clients often come to us with a requirement their usual supplier could not address. Loaded fluids, out-of-catalogue temperatures, uncommon standards — these are the projects we handle best.
Triple Offset Butterfly Valve
Triple offset geometry solves one specific problem: achieving metal-to-metal sealing without wearing the seat on every cycle. The conical disc geometry lifts off the seat from the very first degree of rotation — no friction, no progressive deformation. The result: leakage class VI maintained over thousands of cycles, under superheated steam, in acidic media or under critical pressure.
- DN 50 to DN 3000 — PN 10 to PN 100 / ANSI class 150 to 600 and 900
- Body: grey iron GG25, ductile iron GS400, carbon steel WCB, stainless steel 316
- Discs: SS316, duplex 2205, Hastelloy C276 up to 850°C depending on version
- Certifications: EN12516, SIL 3, Firesafe, fire safety, ATEX, TA LUFT, PED Cat H
Knife Gate Valves
Slurries, cellulose pulps and mineral concentrates quickly clog conventional valves. The knife gate valve eliminates this issue through a full-bore design with no dead cavity. In the closed position, the solid blade provides leak-free sealing on abrasive fluids that other technologies cannot handle.
- Unidirectional, bidirectional through-conduit, bonnet, under-silo, etc.
- Full bore
- Body: stainless steel 316L, duplex 2205, cast iron

Your Questions About Industrial Valves
The same questions come up from one project to the next. Here are the answers.
What is industrial valve technology?
Industrial valves cover all equipment that controls fluids in an installation: valves, check valves, filters, regulators. The difference from plumbing is not a matter of category — it is a question of service conditions. Far higher pressures, extreme temperatures, fluids that attack materials or carry abrasive particles.
In energy, chemical or steel applications, a failed valve does not simply cause a leak. It can trigger a production shutdown, an overpressure event, or a safety incident. Correct sizing is not optional.
Three functions cover the vast majority of needs:
- Isolation: isolating a section of the circuit (gate, butterfly, ball valves)
- Regulation: modulating flow rate or pressure (control valves, regulators)
- Protection: preventing overpressure or backflow (check valves, relief valves)
What is an industrial valve?
An industrial valve is a mechanical device installed in a pipeline to shut off, divert or modulate a flow. It has three components: the body that contains the fluid, the closure element that controls the passage, and the actuator (manual, pneumatic or electric) that drives the closure element.
The right selection relies on four parameters that every process must define:
- Nominal diameter (DN): connection size in mm, from DN 50 to DN 3000
- Nominal pressure (PN or ANSI class): maximum allowable pressure at reference temperature
- Fluid type: water, steam, acid, gas, particle-laden fluid
- Service temperature: from −60 °C in cryogenic applications to +600 °C under superheated steam
A poorly selected valve leaks, wears quickly, or fails under conditions it was never designed to handle. Our configurator uses your process data to identify compatible references; engineers validate before any shipment. That is the foundation of a well-executed industrial valve project.
What are the types of industrial valves?
There is no single industrial valve solution — there are around ten families, each with its own conditions of use. The right choice depends on the function, the fluid and the pressures involved.
- Butterfly valve: 90° rotating disc. A good option for large diameters in water, air and gas, with a smaller footprint than a gate valve. Triple offset for high pressures and temperatures.
- Knife gate valve: solid sliding blade, full bore. No dead cavity, no clogging — that is why it is the standard choice for loaded fluids.
- Ball valve: drilled sphere at 90°, quick opening, good sealing. Widely used in gas, oil and low-pressure steam.
- Gate valve: wedge or parallel closure element. Low pressure drop when fully open. Isolation under high pressures.
- Globe valve: linear closure element. Good flow regulation. Steam and hot water networks.
- Check valve: prevents reverse flow. Protects pumps and compressors.
- Control valve: continuous modulation of flow or pressure via a controlled actuator.
What are the different valve categories?
The valve family (butterfly, gate, ball) is the first filter. In practice, our engineers refine the selection on three additional criteria.
By actuation:
- Manual: handwheel, lever or gearbox. Human operation on site.
- Pneumatic: compressed-air actuator. Fast, well-suited to ATEX zones.
- Electric: motorised gearbox with PLC integration (4-20 mA, HART, Profibus).
- Hydraulic: high torque for large sizes (DN 600 and above).
By body material:
- Grey iron GG25 / ductile iron GS400: water, utilities, low corrosivity
- Carbon steel WCB: steam, hydrocarbons, moderate temperatures
- Stainless steel 316: chemical, food & beverage, corrosive media
- Duplex / super-duplex: offshore, chloride environments, very high corrosivity
- Refractory stainless steels AISI 321 / 253MA / AISI 310
- Hastelloy C22, C276 / Inconel
By applicable standard:
- EN 593, EN 1984, EN 12266: European market
- API 6D, API 609: oil and gas, petrochemical
- PED: pressure equipment, EU market
- ATEX: explosive zones (directive 2014/34/EU)
These three filters apply to any industrial valve project, regardless of the sector.
