Applications
According to Tecofi, the CB4248A-MM is for pumping, water supply, air conditioning and heating installations, the chemical industry and hydraulic installations. Fluids: clear and slightly charged water, demineralised water and non-corrosive products. The valve suits uncharged fluids under a non-pulsating regime.
Features and installation
- Flanged swing non-return check valve with a ductile iron body, range DN40 to DN400.
- Graphite sealing gasket between body and cover; slightly inclined sealing surface for easy closure; low pressure drop and sturdy construction requiring no maintenance.
- Mount on horizontal piping or on vertical piping with ascending flow; the direction is shown by the arrow on the body.
- Epoxy powder RAL 5015, 250 microns, on body and bonnet.
Standards and tests
- Face-to-face according to DIN 3202-F6.
- PN10/16 flange connection according to DIN 2533.
- Hydraulic tests according to EN 12266-1, DIN 3230, BS 5154 and ISO 5208: body 24 bar, seat 17.6 bar.
