YGROS s.r.l. Via Pettinà Luigi, 24 - 36010 Zanè (VI) - Italy

COMPANY COMPANY It all began in 2004, when our engineering team had to find a solution to a particular plant application and came up with a unique solution: a spring-less check valve. This led to the development of a patent covering a technology able to offer an essential, maintenance-free one-way valve, thanks to the total absence of traditional intermediate components. The company developed under the name of Carollo srl, an engineering company with over 40 years of experience in the food, chemical and pharmaceutical sectors. After the success of the first prototypes, the project was constantly...

OUR VALVES EDF EDF - 3A YEV YSV PHARMABALL AGGROBALL WAFER

* Self-draining eccentric version available on request. Suitable for horizontal installation. EDF: Maximum hygiene with no maintenance required. Tightness guaranteed in all installation positions, even vertical with downward flow. The patented YGROS technology sets new standards in the plant engineering world, thanks to its magnetic principle that replaces the function of the traditional spring. uitable for S fluids and steam. Resistant up to 220°C. No more springs that can break or misfire No flow obstruction components No stagnation points Applications Pharmaceutical Chemical Cosmetic Food...

YGROS MAGNETIC PRINCIPLE The main operational difference between a spring loaded check valve and the innovative YGROS valve is the resistance to flow. An ordinary check valve in the open position imposes significant resistance, because the compressed spring pushes the shutter against the flow with considerable force. The magnets built into the valve body keeps the shutter in a closed position. Ygros check valve opens when the inflow pressure exceeds the magnetic force. In the open position the shutter moves away from the magnet, which means lower attraction to the seat and therefore lower resistance...

Once opened, the required pressure to keep the shutter fully open is about 10 mbar. FLOW DIRECTION OPENING PRESSURE HORIZONTAL lines VERTICAL lines VERTICAL lines PRESSURE DROP CHART Graph reading applies to water at 20° C (68°F) installed in horizontal pipes Customizable materials, finishings and further configurations available on request
