Design details
D e s i g n
▪ Wafer-type non-return valve
▪ Shut-off by spring-loaded plate or valve disc guided by
guide pins
▪ Centering aid is part of the valve body
▪ Short face-to-face length to EN 558/49
▪ Exterior coating:
DN 15-100: Body made of brass, without coating
DN 125-200: body made of grey cast iron, coated blue
(RAL 5002)
▪ The valves satisfy the safety requirements of Annex I of
the European Pressure Equipment Directive 97/23/EC (PED)
for fluids in Group 2.
Product benefits
▪ Highly reliable function as plate is accuraby guided by
three guide pins (up to DN 100).
▪ Integrally cast centering aid for easy installation.
▪ Low maintenance requirements due to corrosion-proof
body made of brass (DN 15-100) and spring made of
stainless steel (all nominal sizes).
▪ Universal use: Valve can be installed between flanges to
DIN EN 1092-1 PN 6-16, DIN EN 1092-2 PN 6-16, ANSI B 16.1
25/125, BS 4504 PN 16 and in any installation b.
▪ Cost-effective transport and handling due to short face-toface
length and low weight.
▪ Minimal pressure drop due to hydraulically favourable
flow passage.
