The Elster Meter regulators of the medium pressure are available in a wide range of different nominal pressures, design features and connections. Beside the standard integrated safety shut-off valve (SSV) other safety devices can be chosen as an integrated limited capacity relief valve or a low pressure cut-off. The range of medium pressure regulators encloses balanced one stage inlet pressure regulators and two stage regulators with nominal pressures of PN 1, PN 5 and PN 6. The PN 1 and PN 5 units are fire safe according to the German standard DIN 33822. All units are approved by DVGW according to the pressure equipment directive (PED): PN 1/PN 5 bar in accordance with DIN 33822, PN 6 bar in accordance with EN 334 / EN 14382
