General Purpose Flat Rupture Disc
Product Model: ZD-FL10 (Heavy-Duty Flat Assembly)
Material: Carbon Steel Holders with thickened design; 316 Stainless Steel membrane (standard).
Key Feature: Ruggedized construction for long service life in demanding plant environments (vibration, weather, incidental contact).
Coating: Holders feature a durable, multi-layer industrial paint system (epoxy/polyurethane).
Pressure Range: 1 barg to 25 barg.
Primary Use: General plant and utility overpressure protection for air receivers, water systems, non-hazardous gas lines, HVAC equipment, and outdoor installations.
Overview
Across general industry, countless applications require dependable, "fit-and-forget" overpressure protection. This heavy-duty flat disc assembly is built for precisely that role. It combines a reliable flat rupture disc with a rugged, thickened holder designed to withstand plant vibration, occasional knocks, and harsh weather. The durable paint finish protects against atmospheric corrosion. It is a cost-effective, robust, and no-nonsense safety solution for protecting utility systems and supporting equipment where conditions are tough but the media is non-hazardous.
Features & Benefits
Ruggedized Holder: More material and robust construction compared to standard holders, resisting deformation and physical damage.
Durable Exterior Protection: A high-quality paint system provides excellent resistance to rust, UV degradation, and mild chemical splash.
Reliable & Economical: Offers an outstanding balance of performance, longevity, and purchase price for general industrial duties.
Easy Installation & Maintenance: Standard flange connections and a simple design make installation straightforward. Requires minimal ongoing attention.
How It Works
It is the embodiment of simple, effective safety: a metal membrane fails in tension at its preset pressure, providing immediate relief. The value lies in the durability of the overall assembly, ensuring the disc remains properly installed, protected, and functional for years in a typical plant environment.
Specifications (Descriptive)
Covers the most widely used sizes: DN25, DN40, DN50, DN80, DN100, DN150. Common burst pressures include 4, 6, 8, 10, 16, and 25 barg. Holders are mild steel, fabricated with extra material at stress points. The standard finish is an epoxy primer with a polyurethane topcoat. Bursting membranes are 304 or 316 stainless steel. Gaskets are graphite or reinforced PTFE for broad compatibility.
Q&A
Q: Is this suitable for outdoor installation?
A: Yes, the durable paint system is specifically formulated for weather resistance. For highly corrosive coastal or chemical plant atmospheres, stainless steel holders or a more specialized coating should be considered.
Q: Can it handle wet and oily plant air?
A: Yes. The stainless steel membrane is resistant to mild corrosion from condensed moisture and oil vapors. The graphite gasket is also compatible with these conditions.
Q: What's the difference between this and the Standard Flat Disc (ZD-FL01)?
A: The Heavy-Duty Assembly (ZD-FL10) includes a more robust, coated holder designed for permanent, exposed installations. The Standard Flat Disc (ZD-FL01) typically refers to the disc membrane and basic holder components, often intended for more protected service or where the holder is specified separately.
