Industrial Valves #4736801

Wafer check valves, Hydrodynamic Guided NRVS have introduced yet another design of Non Return Valve Wafer check Valves. Normex wafer check valves are simple in construction have sturdy design & are reliable in operations. These valves are very useful where weight of the valve is required be low & there is a space constraint for valve fitment. The face to face distance in these valves is extremely less as compared to standard valves.Salient Features Sturdy but simple design.100% leak proofShort length - less space required.Light weight.Lower pressure drop across the valve.Low opening & closing pressures.Wide range of materials, temperature & pressure ratingsEfficient flow characteristics.Can be mounted horizontally & vertically.Highly economical.Epoxy coating over the entire surface.

Principal:

Ball Type Check Valves (NRV) B-01 was the first of the valve at Normex with unique design and technology for the first time in India. A very simple and robust design with no mechanism involved. The heart of valve is rubber coated ball. The mechanism hinge-pin-disc used in conventional check valves is eliminated and Normex has put in this rubber coated ball to arrest flow media in return condition.

As the pump starts, the ball moves out totally from the flow path when the pumping is on giving a full bore maximum flow/discharge with minimum head losses. (Fig. A). As the pump stops, the ball rolls back and seats perfectly on the rounded valves seat ensuring totally leak proof sealing.(Fig. B)

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.

Dimensionally compatible with IS 5312 (Face to Face)Can be installed vertically or horizontallyOperates silentlyOperates at temp 80⁰C continuously (for 100⁰Capplication please contact us.)

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: 1.Working principal Hydrodynamic guided closing.2.The closing mechanism is guided & backed with return spring for quick closing, Opening and perfect sealing.3.Due to Aero/hydro dynamic effect water hammer is eliminated.4.Very low pressure loss5.Most suitable for clear liquids & air.6.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.

This is a heavy duty foot valves having all the advantages of standard HGC NRV. HGC footvalves are excellent foot valves for clear water, chemicals etc.

The control application in pumping systems attracted Normex to come out with control Valves i.e. Butterfly Valves. The Normex Butterfly Valve superseded the Gate Valve, Ball Valve and Globe Valve in most spheres of applications. Gas tight sealing with excellent control characteristics and uni directional flow has qualified Normex Valves by most of the industries. The centrally mounted disc, shafts and bearings has minimised head loss. Its low weight and compact design has achieved acceptability in industries like Chemical and Petrochemicals, Watertreatment, Agriculture and many Excellent flow control in quarter turn operationLow pressure dropLow weight, low maintenance, long service life100% tight shut of
