PROVALVE® trays from Koch-Glitsch are designed to eliminate potential for popped, fouled, and stuck valves, with a wide operating range and no moving parts.
The PROVALVE® tray offers the wide operating range of conventional valve trays, but with no moving parts. The valve design prevents valve leg or deck wear and eliminates the potential for popped, fouled, or stuck valves.
The key to the fouling resistance of the PROVALVE® tray is its tapered valve cover, which imparts a forward-lateral push to the liquid flowing across the tray. This directional flow keeps the liquid moving uniformly across the deck, sweeping the deck clean of orifice‐clogging debris.
The directional flow of the PROVALVE® tray also provides uniform liquid and vapor distribution across the entire tray with a low, even spray height across the deck. This increases the trayʹs efficiency, prevents liquid backflow, suppresses jet flooding, and permits operation at greater vapor rates.
