Types of Needle Valves

We manufacture different types of Needle Valves:
  • 3000 series: for pressures up to 255 bar.
  • 6000 series: for pressures up to 425 bar.
  • 600 series : for pressures up to 600 psi.
  • 10000 series : for pressures up to 10,000 psi.
  • Flanged : for use in flanged trunking systems.
  • For high temperatures: with titanium additive that allows operations up to 800 ° C
  • Cryogenic: for a temperature range between -268.9 ° C and 230 ° C at 100 bar

Benefits

Redfluid needle valves are designed to offer high performance. The closing by mobile obturation makes both the opening and the closing of the valve smooth, avoiding the seizure of the sealing seat.

100% of the valves are tested hydraulically and with helium according to API 598. Valves are also supplied with EN 10204 3.1 certificates.

The Back Seating function allows you to change the packing with the circuit operating. When the valve is fully open, this system also prevents fluid from coming into contact with the packing, extending its useful life and reducing maintenance costs.
