QDYQ940F-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 和 9 and sealing-code alternatives H, F and Y. This page separates the 9 drive / F sealing-code / 6 pressure entry as QDYQ940F-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, 长距离输水, 自来水厂和市政供水网络. Confirm flow range, valve sizing, pressure differential and installation duty with KOZO for the intended service.
