Product Overview

The DIN Blue Y Strainer PN16 (Model 5001) is an industrial-duty ductile iron Y-pattern pipeline strainer manufactured to DIN dimensional standards with a distinctive blue RAL 5005 FBE finish. Engineered for continuous service in demanding industrial water and neutral oil systems, the Model 5001 features a GGG50 ductile iron body, removable stainless steel 304 strainer screen, bolted bonnet with EPDM seal, EN1092 PN10/PN16 flange connections, and 100% FBE coating on all surfaces. Available from DN15 to DN400 — the widest size range in the Huaze strainer line — covering everything from small-bore instrument protection to large-diameter transmission main filtration. Manufactured by Shandong Huaze Valve Co., Ltd. (ISO 9001, established 1998).

Where the standard Y strainer protects pumps and valves, the Model 5001 is built for the harsher end of industrial service — cooling water circuits, boiler feed systems, process water with suspended solids, pre-filtration ahead of heat exchangers, and continuous-duty applications where a strainer failure means a production stoppage. The blue FBE coating is not cosmetic — it provides a high-visibility industrial finish that identifies the strainer in complex pipe galleries, with the same 250 um DFT corrosion protection as all Huaze coatings.

Key Features

DIN Standard — European Industrial Specification

Manufactured to DIN dimensional and design standards — the engineering framework trusted by European industrial specifiers, EPC contractors, and plant designers for over a century. DIN-standard strainers provide predictable face-to-face dimensions, standardized flange drilling, and compatibility with DIN-spec pipework and equipment. For industrial projects specifying DIN-compliant components — whether in Europe, the Middle East, Southeast Asia, or Africa — the Model 5001 provides direct specification compliance.

DN15–DN400 — Full Industrial Size Range

From DN15 instrument isolation lines to DN400 bulk water transmission mains — the Model 5001 covers the complete industrial size spectrum from a single product series. This means standardized materials, standardized testing, and standardized documentation across the entire strainer population on a project, simplifying procurement, reducing spares inventory complexity, and providing consistent maintenance procedures at every size. The wide range also enables single-source supply for projects where strainers of different sizes are required in different parts of the same plant.

GGG50 Ductile Iron — Built for Industrial Abuse

EN-GJS-500-7 ductile iron: 500 MPa tensile, 320 MPa yield, 7% elongation. In industrial environments — where strainers may be in continuous service for 8,000+ hours per year, subject to water hammer and system surges, installed in congested plant rooms with potential impact risk, and exposed to aggressive atmospheres — ductile iron's toughness provides a genuine safety margin. It deforms under overload rather than fracturing. At DN400, the body strength of ductile iron against pressure containment and external loading is critical to long-term integrity.

Blue RAL 5005 FBE Coating — High-Visibility Industrial Finish

The distinctive blue fusion bonded epoxy coating applied at minimum 250 um DFT on all surfaces — internal bore, Y-leg chamber, and external body — is electrostatically applied and oven-cured to form a chemically cross-linked thermosetting barrier. Spark-tested at 3 kV on every strainer. In complex industrial pipe galleries where dozens of components share the same space, the blue finish makes strainers instantly identifiable — reducing the time to locate the correct maintenance point during planned outages or emergency interventions. Blue also signals "water service" in European industrial plant colour convention.

Removable SS304 Screen — Fast Cleaning, Minimal Downtime

The perforated stainless steel 304 strainer element (standard 1.5 mm; fine mesh options available) slides into the Y-leg. Bolted bonnet with stainless steel A2-70 fasteners and EPDM gasket. Cleaning procedure: isolate, depressurize, remove bonnet, withdraw screen, clean, reassemble — in minutes, with standard tools. In industrial environments where every hour of downtime costs production, the fast-access Y-leg design minimizes maintenance windows. The stainless screen resists corrosion indefinitely.

Low Maintenance by Design

Beyond the accessible strainer screen, the Model 5001 is a passive device — no moving parts, no actuators, no seals subject to stem cycling, no wearing components requiring periodic replacement. The only maintenance action is periodic screen cleaning, triggered by differential pressure monitoring or a scheduled interval. The bolted bonnet design ensures confident resealing after every cleaning cycle. No special gaskets, no special tools, no specialist training required.
