High-pressure shut-off valve VD 50.44.60

The high-pressure shut-off valve VD 50.44.60 has been especially developed for the use in nuclear power plants for liquid media and steams at temperatures of up to 400C and pressures up to 268 bar.

The gland packing is made of multiple layers of graphite and is free of asbestos.

The gland packing is constructed in such a way that the so-called gland nut can be tightened during operation.
