E.E: What’s the news about new products?

T.L: SAPAG VALVES has developed a new product the V17: the 3-piece technology forged ball valve  with floating ball and gryogenic option.

The V17 has an outstanding performance record: Diameter (DN): 8 to 150 I Pressure (bar): 220 max I Temperatures (°C): -40 to 350°C I Reduced bore / integral I Steel / stainless steel version I Integrated pressure relief system as standard I Integrated ISO 5211 base for easy automation I Two lip seats coupled with two body seals guarantee the tightness I Screwed connections in the body I Available in weld end (BW and SW), gas threaded / gas tapered / NPT, flanged (PN, Class), or other finishes on request I Face to face: EN 12982 / EN 558 Series 1 I Anti-ejection and anti-loosening system with force recovery guaranteeing a perfect seal with a series of gaskets I  Design standards: EN 13445 / DIN 3840 / EN 12516.3 I Sealing standards: NF EN 12266 / ISO 5208 Rate A I Flanged standards: EN 1092-1 / EN 1759-1 / ISO 7005

The gryogenic version of the V17 with extension 300 mm stands out thanks to its many features: Full or reduced passage I Stainless steel construction I Integrated ISO 5211 base for easy automation I Wide range of seat materials I Temperature range: -196 °C to +80 °C I Pressure equalization port on the upstream side of the ball I Seats specially machined for cryogenic applications I Vertical mounting of the axis extension is mandatory I Pressure: 100 bar maximum depending on the valve diameter and seat material I Valve designed in accordance with the NF EN 1626 standard I The valves are degreased in accordance with EN 12300 I The valves are individually packed in polyethylene bags.

E.E: At what stage is the market where you are currently active?

T.L: Our market is currently growing in certain segments, such as general industry, chemical and pharmaceutical industry, marine, oil & gas.

But also, in the launch phase on the water markets, because the main players come from developing countries.

E.E: What can you tell us about market trends?

T.L: As an ethical company, committed to sustainable development, to improving the living conditions of developing countries and aware of the many environmental issues, we are committed to supporting the various players in the water market, in the various fields of application such as water transport, drinking water, water recycling, wastewater treatment and desalination, by providing quality products Made in France and providing the most suitable solutions to their different needs.

E.E: What are the most innovative products marketed?

T.L: The MONOVAR® control valve is one of the most innovative products marketed by SAPAG valves. It is a pressure and/or flow control valve developed for intelligent fluid control.

In the MONOVAR®, thanks to the division of the flow into numerous small jets (several dozen orifices per plate, distributed over the entire surface), this dissipation takes place under the best conditions.

This results in:

  • The reduction of flow fluctuations due to the reduced energy of each jet and the characteristic small size of the induced turbulence of these jets. In addition, the disturbances propagate only a short distance downstream of the valve, which allows the reduction of the minimum distance generally recommended between a valve and the nearest device: flowmeter, turbine…
  • A better number of cavitation starts than conventional valves.
  • Excellent behavior in the presence of cavitation because it is transferred to the fluid (mixing cavitation), far from the vital parts of the valve (unlike conventional valves where cavitation appears on the obturator, the seat, the trunnions, etc.). 
  • There is also no formation of steam pockets under the intended conditions of use, which reduces the risk of pressure pulsation. 

The CLASAR® check-valve is another of the most innovative products marketed by SAPAG valves. It prevents water hammer in pipes, for example in the event of an emergency shutdown of a pumping installation. The absence of a flapper makes its operation quieter. It allows a quick stabilization of the downstream flow. It is easy to install with a choice of vertical (rising fluid), horizontal or diagonal mounting.

In a pipeline or pumping station, the check valve is a frequently operated device. Statistically, a large number of dangerous water hammer events are due to the valve not being suitable for the installation. 

The CLASAR® meets this requirement thanks to its short face-to-face design, which reduces the travel of the valve. The absence of friction and therefore of seizure, as the design does not include a guide pin. The density of the valve material is equal to the density of water (no inertia of the valve in water, due to its low mass)

  • The spring improves the closing time.
  • Thanks to its elasticity, the plug, when placed on its seat, does not create any shock when closing.

E.E: What estimations do you have for 2023?

T.L: Despite the increase in the cost of raw materials, the cost of energy, the cost of labour, administrative constraints and production taxes, we remain very enthusiastic and optimistic about our economic development for 2023, thanks in particular to our presence to intensify on the continents of Africa, the Middle East and Asia, which translates into an increase in our order book.
