Parker U Series Union Bonnet valves Parker 針閥 - Parker Needle Valves
Needle Valve,Union Bonnet 6,000 PSI - U Series
針閥，聯合閥帽 6,000 PSI - U 系列 | #6A-U12LR-G-SS-HT

派克的聯合閥帽針閥 U 系列設計用于高壓和高溫儀表和工業(yè)應用。這些嚴苛工況針閥在螺紋下方有填料以保護閥桿.派克的 U 系列聯合閥蓋閥設計用于壓力高達 6,000 (414 bar) 和溫度高達 1,200°F (649°C)。重型設計具有不旋轉的下部閥桿，通過消除閥桿在填料區(qū)域的旋轉，有助于延長填料壽命。螺紋下方的閥桿填料將螺紋潤滑劑與流體隔離開來，無論介質如何，都能確保充分潤滑。

Parker union bonnet needle valves, U Series have been engineered for use in high pressure and high temperature instrumentation and industrial applications. These severe service needle valves have packing below the threads to protect the valve stem. Parker U Series Union Bonnet valves are engineered for use at pressures up to 6,000 (414 bar) and temperatures as high as 1,200°F (649°C). The heavy duty design has a non-rotating lower stem that helps to extend packing life by removing stem rotation through the packing area. Stem packing below the threads isolates the thread lubricant from the flow, ensuring adequate lubrication regardless of the media.

Markets:
- Power
- Nuclear Plants
- Oil and Gas
- Chemical / Petro-Chemical
Features/Benefits:
- Union bonnet design ensures high integrity seal under severe service applications
- Packing below the power threads protects thread lubricants from media and isolates the lubricants from the media
- Dust seal in the packing nut protects stem threads from external contamination
- Stem swivel above the packing eliminates entrapment area and increases packing life
- Choice of Grafoil or PTFE packing
- Choice of Regulating or Blunt stem types. Blunt stem type helps combat wire draw which may occur when two phase flow is present (i.e. steam service)
- 316 stainless steel construction
- Wide variety of US Customary and SI ports
- Panel mountable
- 100% factory tested

Applications:
- Steam Blow Down Service
- Process Control Lines
- High Temperature Sampling Lines
