TECHNICAL DATA SHEET

Product: 1″ – Class 300 Floating Ball Valve
Material: Monel K400 (UNS N04400)
작동: Manual / Actuator-Ready (Optional)

General Description

This floating ball valve is manufactured from Monel K400 (UNS N04400) , a nickel-copper alloy renowned for its exceptional corrosion resistance in seawater, hydrofluoric acid, and reducing environments. The 1″ Class 300 configuration is designed for high-pressure, corrosive service applications where stainless steel may be inadequate. The floating ball design provides tight shut-off and reliable sealing, making this valve ideal for marine, chemical processing, oil & gas, and aerospace industries.

주요 특징

Superior Corrosion Resistance: Monel K400 offers outstanding resistance to seawater, hydrofluoric acid, and a wide range of reducing acids and alkaline solutions. It is immune to chloride-induced stress corrosion cracking (SCC), making it superior to 316 stainless steel in marine environments.
Floating Ball Design: The ball is not trunnion-supported; line pressure forces the ball against the downstream seat, ensuring bubble-tight shut-off even at low pressures.
Forged Monel Construction: Body, ball, and stem are manufactured from forged Monel (ASTM B164 and B865), ensuring a dense, defect-free microstructure with consistent mechanical properties.
Blowout-Proof Stem: The stem is retained by a shoulder beneath the packing, preventing accidental ejection under pressure.
Anti-Static Device (Optional): Conductive path between ball, stem, and body dissipates static charge for flammable service applications.
Fire Safe Design (Optional): Available with fire-safe seat design compliant to API 607 or ISO 10497.

Operating Torque & Actuator Interface

For automated applications, the valve can be supplied with an ISO 5211 direct mount platform.

Oil & gas (sour gas, produced water)
Aerospace (fuel and hydraulic systems)
Alkaline and reducing acid environments

Notes for Ordering

Monel K400 vs. K500: The valve body and ball are typically K400; the stem is often upgraded to 모넬 K500 for higher strength and wear resistance.
Seat Selection: PTFE is suitable for general service up to 150°C. For higher temperatures (up to 250°C) or abrasive media, PEEK seats are recommended.
End Connections: Confirm flange rating (Class 300) and facing (RF or RTJ) or threaded end type (NPT or socket weld) prior to ordering.
작동: Specify if ISO 5211 mounting is required for future automation.
