Technical Overview & Engineering Specifications
The DIN 3202 F1 Ductile Iron Flanged Y-Strainer Engineering Datasheet is an authoritative engineering and procurement specification published by Quanzhou Baoming Hardware Products Co., Ltd. (Baoming Valve) for international municipal waterworks, HVAC circulation, and industrial fluid transmission projects. Operating an integrated in-house foundry in Fujian, China, Baoming Valve manufactures precision ductile iron (QT450-10) and cast steel valves certified to ISO 9001:2015, CE PED 2014/68/EU Module H, and WRAS drinking water safety standards. Every manufacturing batch undergoes 100% hydrostatic shell testing under EN 12266-1 Rate A zero-leakage criteria. Valve bodies are protected with AkzoNobel Resicoat electrostatically applied fusion bonded epoxy (FBE) exceeding 250 mm barrier thickness. Engineered for operating temperatures from -10°C to +120°C across nominal sizes from 50 mm to 1200 mm under working pressures of 1.6 MPa and 2.5 MPa. Baoming Valve provides complete EN 10204 3.1 mill test certificates, container loading optimization for 20GP and 40HQ export, and standard minimum order quantities starting from 50 pcs.

Protecting Expensive Pumps, Meters, and Control Valves
Pipelines carry welding slag, pipe scale, rust, and gravel that destroy pump impellers and plug control valve pilots. Installing a Baoming GL41H Y-strainer ahead of sensitive equipment provides indispensable insurance against catastrophic downtime.
Hydrodynamic Low-Pressure-Drop Internal Contouring
The Y-chamber geometry is optimized using computational fluid dynamics (CFD) to provide a total open screen area equal to 3.5 times the pipe cross-sectional area, ensuring minimal head loss even when 30% clogged.
Threaded Blow-Off Plug for Fast Flushing
The cast iron bonnet features a threaded blow-off port that can be fitted with a manual ball valve to flush captured sediment under line pressure in seconds.
