QDYQ340F-6 Piston Flow and Pressure Regulating Valve
The pressure-specific model heading on printed page 06 of the KOZO flow and pressure regulating valve catalog shows drive-code alternatives 3, 6 و 9 and sealing-code alternatives H, F and Y. This page separates the 3 drive / F sealing-code / 6 pressure entry as QDYQ340F-6; body-material codes are not multiplied into unverified products.
Features and applications
The piston-type design adjusts the flow passage for flow regulation and pressure management. The catalog describes reservoir discharge, long-distance water transmission, waterworks and municipal water networks. Confirm flow range, اندازه دریچه, pressure differential and installation duty with KOZO for the intended service.
