Product Description

Union Bonnet Needle Valves
HJZF4 Series: 6000 psig
HJZF4H Series: Working pressure up to 10000 psig
Features

• One-piece forged body
• Two- stem design: Upper stem threads cold rolled and lower stem hardened for high strength and smooth operation
• Accidental valve disassembly disabled by union bonnet construction
• Upper stem thread lubricant isolated from system media
• Linear instead of rotary movement of the rising, non-rotating stem minimizes packing abrasion and reduces the friction between the seat and the tip
• Safety back seating seal in fully open position
• Panel mounting available
• Steady and durable fastening of the handle by double lock-pins
• Handles of different colors available
• Every valve leak tested with Nitrogen or compressed air (HJZF4 Series) at the maximum allowable working pressure or with water (HJZF4H Series) at 1.1 times the maximum allowable pressure
• Working pressure up to:
  HJZF4 Series---Stainless steel: 6000 psig (414 bar)
                                    Alloy C-276: 6000 psig (414 bar)
                                    Alloy 400: 5000 psig (345 bar)
  HJZF4H Series Stainless steel: 10000 psig (690 bar)
• Working temperature: 
  PTFE: -65°F to 450°F (-54°C to 232°C)
  PEEK: -65°F to 500°F (-54°C to 260°C)
  Graphite: -65°F to 1200°F (-54°C to 649°C)
