1. Design
Lift check valve to DIN/EN with wafer-type body, centring aided by the body shape, shut-off by spring-loaded plate or valve disc guided by three stainless steel guiding pins. Low-noise designs with plastic plate (DN 15-100) or valve disc with O-ring (DN 125-200), maintenance-free.
2. Application
Industrial plants and heating systems, liquids and gases, hot-water heating systems, high-temperature hot water heating systems, heat transfer systems. Any limits given in the technical codes must be complied with. Not suitable for fluids liable to attack the materials used. Other fluids on request.
| Material | EN-GJL 250 |
| Nominal sizes | DN 15 to DN 200 |
| Nominal pressure | PN 6/10/16 |
| Permissible operating temperature | -20 to +250°C |
| Permissible operating pressure | 16 bar |
1 Highly reliable function as plate is accurately guided by three guide pins (up to DN 100).
2 Integrally cast centring aid for easy installation.
3 Low maintenance requirements due to corrosion-proof body made of brass (DN 15-100) and spring made of stainless steel (all nominal sizes).
4 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.
5 Cost-effective transport and handling due to short facetoface length and low weight
6 Minimum pressure loss by hydraulically favourable flow passage
