Low Flow Pressure regulators
These precision pressure regulators include Models 52, 31, R10, R11, 10T, 10W. They feature single or two‑stage structure, 1/4" NPT(F), SS316L & nickel‑plated copper body, PTFE seat, and double‑layer filter. Max inlet pressure reaches 3000 psig with stable outlet control. Low leakage, wide temp range, easy installation. Ideal for gas systems, laboratories, and industrial equipment.
