Uni-Lok Relief Valves

Relief valves are a critical safety component designed to protect systems from overpressure, ensuring safe and reliable operation even in the most complex gas environments.

Uni-Lok safety relief valves operate from low pressures up to higher pressures of 6000 Psi.

Our Uni-Lok relief valves feature:

  • Compact designed one-piece body to reduce space
  • Low friction bonnets to increase both accuracy and to improve consistency of cracking and reseal pressure
  • Lock wire to secure a given set pressure
  • Identifying colour coded springs and labels indicate spring cracking/relief pressures
  • Selective and replaceable springs with narrow pressure ranges
  • VR3 series – one spring for all set pressure ranges up to 3000 Psi
  • VR6 series – 7 replaceable springs for a variable pressure solution up to 6000 Psi
