Stainless steel needle valve with coupling adapter sleeve
The needle valve 15NZH54BKM coupling with a coupling adapter (DN 15; PN 160/250) has the following advantages:
easy installation of the differential pressure gauge inlet to the valve outlet, which significantly reduces installation time.;
reducing the number of embedded devices, which reduces the final cost of the equipment;
The adapter sleeve has an opening designed for smooth discharge of residual pressure during disassembly of the differential pressure gauge for inspection/replacement, which increases the safety of routine maintenance.
Working media: (stainless steel body parts 12X18H10T) water, steam, petroleum products, alkaline mixtures, acids that are not aggressive to the materials of the valve parts.
