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 loss
5.Most suitable for clear liquids & air.
6.Silent operation.
