Pressure Reducing Valves
Armstrong pressure reducing valves deliver precise downstream pressure control for steam systems. The GP-2000K externally piloted, diaphragm-operated design provides ±1% accuracy with a 20:1 turndown ratio, high Cv, and a rugged ductile iron body rated to 300 psig.

GP-2000K Series — Externally Piloted PRV
The GP-2000K is an ideal choice when set-point changes are frequent and access to the PRV is difficult. The valve comes totally assembled and requires no field installation except downstream sensing line and air connection. Hardened stainless steel working parts, double stainless steel diaphragms, and in-line repairability add up to reliability on the job. Single-seated for dead-end service.
