Subject: Bar Stock Needle Valve tech. Уважаемые коллеги!Помогите, пожалуйста, разобраться, что это за арматура: Bar Stock Needle Valve Можно ли его так обозвать: игольчатый клапан пруткового проката With a wide range of patterns, sizes, end connections, seating arrangements and stem types available, Parker forged or bar stock valves provide complete flexibility in any layout from miniaturised tubing to piping systems up to 3/4". Most valves can be supplied with the famous A-lok twin ferrule, as well as the CPI single ferrule, compression fitting in materials compatible with the valve construction. A number of valves in this specification sheet have interchangeable stems offering fine flow control, positive metal to metal shut off or Kel-F stems. Kel-F stems are recommended for positive, repetitive shut off with low density gases and non-lubricating fluids, where operating conditions will permit. For applications involving mediums heavily contaminated with rust, sand, grit and similar solids, a delrin seat is recommended. Rugged, compact Parker forged and bar stock needle valves afford exceptional versatility for ease of installation and demanding service, with documented heat code traceability on stainless steel bodies for critical applications. Заранее спасибо!
