221S15F-495905BB solenoid valve is a pilot operated 2/2 normally closed fluid control valve manufactured by Parker Hannifin USA, widely adopted for marine fuel, bilge water and hydraulic pipeline cut-off control.The valve body is fully constructed of marine grade 316 stainless steel with FKM fluororubber diaphragm seal, providing outstanding resistance to seawater corrosion, fuel oil erosion and wide-range chemical media. The 1/2 inch female thread connection and 15mm flow orifice support stable flow control under working pressure up to 10 bar.The matched explosion-proof coil part No.495905BB carries full IECEx and ATEX hazardous area certification, rated IP65 dust and waterproof, and operates reliably from -40°C to 80°C under 240V AC power supply.This valve is extensively installed on cargo ships, oil tankers and work vessels as original spare fluid shut-off components for fuel supply pipelines, oily bilge separation systems and auxiliary machinery liquid circuits.
