The Resideo Flanged Two-Way Linear Valve (DF) is a single-seated valve designed for the modulating control of hot or chilled water, as well as steam, within heating, ventilation, and air conditioning (HVAC) systems. These valves are specifically engineered for high differential pressure applications, such as district heating. They can be seamlessly operated by the linear actuators in the ML64... and ML74... series.

Special Features:

• Pressure-balanced plug for enhanced stability
• Nodular iron body with durable flanged end connections
• Low seat leakage rate to ensure efficiency
• Metal-to-metal seating for longevity and reliability
• Self-adjusting packing that maintains performance
• Precise positioning for cutting-edge temperature control
• Direct-coupled electric configuration for straightforward installation

The FSDCDFA Forward Acting Rupture Discs are composite conventional discs formed by three parts: a slotted, perforated metal part, a seal membrane (usually in PTFE but also available in many other metallic or non-metallic materials) and a protection section. It is excellent for use with gas and liquids in static conditions and excellent for low pressures. FSDCDFA discs react to excessive pressure with total opening in a few milliseconds without fragmentation. They are therefore recommended for valve protection. Supports may be provided for vacuum or counter-pressure protection. Composite FSDCDFA rupture discs may also be used for simultaneous protection from pressure and vacuum.
