Pressure-Reducing, Spring-Loaded
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
