PED Conformity Statement and Information
The CS400 Product Series is in conformity with the Pressure Equipment Directive PED 97/23/EC.The exception to this previous statement is the Type CS403 which is not yet certified to conform
with the PED Directive.
Pressure regulator does not require any supplementary upstream safety accessory for protection against overpressure compared with its design pressure PS, when upstream reducing station is sized for a max downstream incidental MIPd <= 1.1 PS.
Principle of Operation
Type CS400 Base Regulator Operation
Refer to Figure of Fisher CS400 Series When downstream demand decreases, the pressure under the diaphragm increases. This pressure overcomes the regulator setting (which is set by the regulator control spring). Through the action of the pusher post assembly, lever, and valve stem, the valve disk moves closer to the orifice and reduces gas flow. If demand downstream increases, pressure under the diaphragm decreases. Spring force pushes the pusher post assembly downward, the valve disk moves away from the orifice, and the gas flow increases downstream as the regulator opens in response to the decreased pressure underneath the diaphragm.
The Type CS400IR regulator includes an internal relief valve for overpressure protection. If the downstream pressure exceeds the regulator setting by 7 to 28 inches w.c. / 17 to 69 mbar (depending on the main spring used), the relief valve opens and excess gas is vented through the stabilizer vent in the upper spring case.
General Installation Instructions
Before installing the regulator,
Installation Location
The installed regulator should be adequately protected from vehicular traffic and damage from other external sources.
