Pressure-Reducing, Spring-Loaded

Pressure-Reducing Spring-Loaded Regulators

Pressure-Reducing Spring-Loaded Regulators

  • Reduce downstream pressure and keep it constant, even when inlet pressure or flows fluctuate
  • Control inlet pressures up to 10 150 psig (700 bar)
  • Minimize droop in conditions with flow and pressure fluctuation
  • Are suitable for gas or liquid and high-purity or high-flow applications
  • Are offered in bottom-mounting, self-venting, tamper-free designs, as well as panel-mounting, convoluted and non-perforated diaphragm, metal or polymer seats, and two-stage configurations
