Needle Valves - LN Series Locked Bonnet Needle Valves
SSP is now offering LN Series Locked Bonnet Needle Valves for demanding applications with pressure up to 6000 psig (413 bar) and temperature from -65 to 1200°F (-53 to 648°C). LN Series valves can improve safety and productivity and reduce maintenance and installation costs when compared with union bonnet and other severe service designs. LN Series Needle valves offer:
Locked bonnet design which prevents accidental disassembly during operation, maintenance and from system vibration.
Live-loaded chevron reduces the need for packing adjustments and maintenance
Non-rotating stem which can eliminate seat damage and reduce packing wear
Stem threads above the packing to prevent system media from infiltrating the threads and washing away thread lubricants
