Reliance RWC 8 Litre Aquasystem Potable Expansion Vessel Pre Set 3 Bar - XVES050030

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.

The Resideo Braukmann D04FM pressure reducing valve is expertly designed to protect domestic water systems from excessive supply pressure. This versatile valve is also ideal for industrial and commercial applications within its specified operating range. By effectively regulating the inlet pressure, it prevents damage from over-pressurisation while promoting reduced water consumption. The valve guarantees a stable outlet pressure, even during significant fluctuations in supply pressure, ensuring a consistent flow and minimising noise throughout the system. The D04FM serves as an excellent solution for both residential and commercial or industrial installations.
