5.4.1.3 Design details
Design
Valves to type series booklet 7150.1
▪ Straight-way or angle pattern with horizontal seat
▪ Throttling plug ≤DN100
▪ On/off disc ≥DN125
▪ All nominal sizes with position indicator, locking device and travel stop
▪ Compact bonnet
▪ Maintenance-free bellows-type stem seal with back-up gland
▪ Non-rising handwheel
▪ Flanges to DIN EN 1092-2 Type 21
▪ Exterior coating: blue,RAL5002
▪ The valves satisfy the safety requirements of AnnexI of the European Pressure
Equipment Directive2014/68/EU (PED) for fluids in Groups1and2.
▪ The valves do not have a potential internal source of ignition and can be used in
potentially explosive atmospheres, GroupII, category2 (zones1+21) and
category3 (zones2+22) to ATEX2014/34/EU.
▪ Type-tested to the specifications of Germanischer Lloyd and Bureau Veritas.
Variants
▪ V-port plug (seat-guided throttling plug for maximum requirements) for DN15
to300
▪ Valve disc with PTFE ring (≤200°C, throttling plug for DN15 to100, on/off disc
for DN125 to200)
▪ Lead-sealable cap (prevents unauthorised actuation) as assembly set
▪ Balanced plug ≥ DN200
▪ High-temperature resistant paint (grey aluminium)
▪ Either one or two limit switch(es) as assembly kit for globe valves of DN15 to150
made of EN-GJS-400-18-LT
▪ Oil-free and grease-free: lubricated exclusively by mineral oil free lubricants
approved by the German Federal Office for Materials Testing (Bundesanstalt für
Materialforschung und -prüfung, BAM)
▪ Other flange designs
▪ Low-temperature steel bolts for temperatures down to -30°C (EN-GJS-400-18-LT
only) up to 0.75xPN (max.)
