QDYQ640Y-10 Piston Flow and Pressure Regulating Valve
The pressure-specific model heading on printed page 07 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 6 drive / Y sealing-code / 10 pressure entry as QDYQ640Y-10; 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.

C, 我, P and R remain selectable body-material codes. The actual body grade, seat material and temperature capability must be confirmed together for the selected configuration. The sealing-code letter is preserved from the source, not used to invent a specific alloy or unverified temperature rating. Air-supply pressure, fail-safe action, positioner and actuator torque are order-specific. No special-alloy, cryogenic or certification claim is inferred.
Original image reference
The main image is an original catalog valve-body sectional detail; it is not a product photograph and does not depict a pneumatic actuator. The image carries a KOZO VALVE watermark and retains the original catalog structure without generated hardware. Only the shared valve-body detail is illustrated; no manual or electric assembly is passed off as pneumatic. Request a configuration-specific drawing and actual product photograph before confirming an order.
