Needle Valves

• Two-piece stem design: The upper stem threads are specially hardened, and the lower stem surface is roller burnished for hardening.
• The lubricant on the upper stem threads is isolated from the process media.
• The non-rotating lower stem moves linearly up and down instead of rotating during travel, reducing packing friction per stroke and minimizing galling between the seat and the plug.
• The valve provides back-seating functionality in the fully open position.
• Panel mountable.
• Each valve is helium leak-tested at rated working pressure prior to shipment.
• Maximum Working Pressure
