Normex  Valves Pvt. Ltd. brings this latest technology for the first time in India. Silent Check Valves‎ are a short length double flanged valves with all the internals designed Hydrodynamically. This valves, when open, the annular area between the body plunger available for flow, is equal to the nominal bore area. Therefore, unlike other spring loaded valves conventional flapcheck valves, these valves offer lower head losses maintains laminar flow. As the valve closes, due to return spring force, valve is “Quick Closing”. The valve gets closed before the start of back flow / return velocity. Hence, water hammer is eliminated in most of the cases.

Features:

• Working principal Hydrodynamic guided closing.
• The closing mechanism is guided backed with return spring for quick closing,
• opening perfect  sealing.
• Due to Aero/hydro dynamic effect water hammer is eliminated.
• Very low pressure loss
• Most suitable for clear liquids air.
• Silent operation.

Rubber Lined Check Valves (Flanged) are lined internally with Ebonite Hard rubber so that media does not come in contact with metal. This Model is most suitable for corrosive/erosive applications. The overall dimensions of this valve will be similar to standard Ball NRV bur face. To face length will br more by 6-10mm.

Salient Features:

1. Lowest possible pressure drop across the valves.
2. 100% leak proof sealing years over years.
3. Non-clogging and self cleaning as ball rotates during operation.
4. Virtually no wear and tear, no maintenance and longer service life.
5. Higher solid handling capacity due to full bore and straight internal path.
6. Lower head loss-high discharge, reduced pumping time-All leading to Energy Saving.

Applications:

Clean water, Raw water, Sewage, Slurry, Waste water, Viscous liquids etc.

Used in industries like:

Fire fighting, Plumbing, Water distribution, Water/Sewage treatment, Irrigation/agriculture, Sewage plants, Steel mills, Power stations,
Chemical/process industries, HVAC, Sugar/food industry, Breweries, Mining and many more.

This Ball Check Valves is designed specially for lower pressure applications where the pipes are threaded. The working principal and features are as model B-01 giving all the advantages of the Ball Type design.

The typical applications are domestic pumping, low rise building pumping, small irrigation systems. The working pressure is 6 bar.

• Sturdy but simple design.
• 100% leak proof
• Short length - less space required.
• Light weight.
• Lower pressure drop across the valve.
• Low opening closing pressures.
• Wide range of materials, temperature pressure ratings
• Efficient flow characteristics.
• Can be mounted horizontally vertically.
• Highly economical.
• Epoxy coating over the entire surface.
