Wafer Double Plate Check Valve Cast Iron / Stainless Steel
Product Details
The wafer dual plate check valve features a wafer-type connection and a dual semi-circular butterfly plate design. This valve delivers exceptional sealing performance, low flow resistance, and reliable operation across a wide range of media and working conditions.
With a dual-plate structure and flange-end connection, this check valve combines fast response, reliable sealing, and ease of installation. The double plate flange check valve allows for secure mounting between pipeline flanges and is easy to remove for inspection or replacement. The compact construction saves space, while the non-slam closing action minimizes water hammer and vibration within the pipeline.
