Description
Main Applications
– Hot-water heating systems
– Air-conditioning systems
– Chemical industry
– Process engineering
– Heat recovery systems -
Advantages
– Highly reliable function as plate is accurately guided by three guide pins (up to DN 100).
– Integrally cast centring 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 position.
– Cost-effective transport and handling due to short face-to-face length and low weight
– Minimum pressure loss by hydraulically favourable flow passage -
