Industrial AP4650SM 3PWD FV4 MV4 MV4 Manual Diaphragm Valve

AP4650SM is a three-port manual diaphragm valve from AP Tech Process Gas Equipment, designed for precise, leak-tight control of gases in high-purity delivery systems and analytical instrumentation lines. The 3PW designation denotes a three-port butt-weld configuration, while FV4 and MV4 specify the connection variants: FV4 is a 1/4 inch face-seal female port, MV4 is a 1/4 inch face-seal male port, enabling compact inline assemblies. As part of the AP4650 series, this valve is intended for process-gas service where reliable isolation and flow control are required, and it is suitable for platforms that emphasize cleanability and contamination control. Additional porting options such as TW4 (1/4 inch tube weld) extend configuration freedom, allowing designers to pair the valve with tubing runs or welded lines without changing the fundamental compact footprint. This model is manual, eliminating the need for external power to operate in field or lab settings, and it is commonly specified for gas delivery manifolds, test rigs, and analytical instrumentation lines where controlled shutoff and isolation are essential.
