Plast-O-Matic IDA Series quick dump valves are ideal for quick fluid release from plumbing systems or HVAC devices with high efficiency. They have a double-acting air-operated mechanism that allows bidirectional flow control and a normally-closed configuration that maintains the closed position, even when not actuated. These valves provide a bubble-tight seal to withstand pressures of up to 25 inches of water with minimal leakage. They have a large flow area for ultra-fast drainage of fluid to reduce system downtime.
