F Series Manifolds
General Features
Manifolds and Manifold-Combinations I Features and Benefits

AS-Schneider F Series Manifolds and Manifold-Combinations are designed, manufactured and tested with respect to the relevant Standards applicable in this field. Manifold-Combination means the welded assembly of a 3 Valve Manifold and 2 Blowdown Valves. All the manifolds contained in this catalogue are for direct mounting according to DIN EN 61518 (IEC 61518).

According to DIN EN 61518 the manifold-transmitter interface is applicable for a max. allowable (Working) Pressure (PS) of 413 bar and a max. allowable Temperature (TS) of 120°C for liquids, gas or vapors. The max. allowable Temperature (TS) of 120°C is considering the requirement that manifolds and transmitters need to be protected against heating by hot media. This can be achieved by using adequate hookups or by instrument impulse lines with sufficient length. However the AS-Schneider F Series Manifolds can be used for temperatures up to 300°C, PTFE up to 232°C, Graphite up to 300°C. The Blowdown Valves of the Manifold-Combinations can be used for temperatures up to 550°C - mainly used in Power Plants.
