Dual Plate Check Valve
Aarya Sales supplies dual plate check valves (double plate / wafer type NRV) in India, designed for efficient backflow prevention in industrial systems. These valves feature a compact, lightweight design with two spring-loaded plates mounted on a central hinge, allowing quick and smooth closure.
Dual Plate Double Flanged Check Valve
Dual Plate Wafer Check Valve
The dual plate design reduces cracking pressure and pressure drop, while the spring-assisted mechanism ensures tight sealing and minimizes water hammer and slamming effects. These valves are inherently fire-safe by design and suitable for demanding applications.
Sourced from trusted manufacturers, dual plate check valves are widely used in industries such as water treatment, oil & gas, power generation, and process plants, handling media like water, oil, gas, and steam with reliable performance and long service life.
Dual Plate Check Valve Supplier in India — Aarya Sales
Dual plate (double door) check valves use two spring-loaded half-discs hinged on a central pin, closing faster and with less water hammer than swing or single-plate designs. Aarya Sales supplies dual plate check valves in wafer and double-flanged body styles, sizes 50 NB to 600 NB, Class 150# to Class 600#.
Materials: Cast Iron, Carbon Steel (A216 WCB), Stainless Steel (CF8/CF8M). Lightweight, low-pressure-drop design suited to pump discharge and high-velocity pipeline protection.
Frequently Asked Questions
A dual plate (double door) check valve has two semicircular discs hinged on a central pin, each spring-loaded to close independently. This design closes faster than a single-disc swing or wafer check valve, significantly reducing water hammer and disc slam — while being lighter and more compact than a swing check valve of the same size.
Dual plate check valves are lighter, more compact, close faster (reducing water hammer), and have a lower pressure drop than traditional swing check valves — making them well suited to pump discharge and high-velocity pipeline service.
We supply dual plate check valves in wafer (between-flanges) and double-flanged body styles, from 50 NB to 600 NB, Class 150# to Class 600#, in Cast Iron, Carbon Steel, and Stainless Steel.
Yes, most dual plate check valve designs are suitable for both horizontal and vertical (upward flow) installation, unlike traditional swing check valves — confirm orientation suitability against the specific model's spring configuration.
