AI Overview
A995 4A (CD3MN) wafer check valves are high-strength duplex stainless steel, non-return valves, commonly used in corrosive environments like seawater, oil, and gas, offering superior corrosion resistance and strength. These compact valves often feature a dual-plate, spring-loaded design per API 594, ideal for reducing water hammer and fitting between pipes with minimal space. Typical options include this 8" 300LB Dual Plate Wafer Check Valve or this 12” 150LB model.
