Product Description
Danfoss PCV-VFG 21 pre-assembled self-acting control valve (OEM designation "Assem.kit PCV-VFG21 PN25 150/320 flange"). Shipped as a factory assembly kit combining a Danfoss AF-series rolling-diaphragm actuator with a VFG 21 grey cast-iron globe body, ready to install as one unit for differential-pressure / pressure control. No external power or control signal is required — pipe pressure acting on the 630 cm² diaphragm holds the set differential pressure across the load. Valve size DN 150; PN 25; Kvs 320 m³/h; Flange connection; differential-pressure setting 0.5–12 bar; control ratio 400:1; media District heating/cooling circulation water (Glycolic water up to 30%), 2 °C to 150 °C. Body Cast steel EN-GP-240-GH (GS-C 25); stem Normally closed; leakage rate 0.05 % Kvs. OEM P/N 003G1525. Technical data quoted verbatim from store.danfoss.com (code 003G1525). Used in commercial refrigeration, provision-room cooling and reefer plant rooms across HFC, HFO and CO2 (R744) refrigerants.

Compatibility & Fitment
The PCV-VFG 21 kit is a complete self-acting control valve (AF actuator + VFG 21 grey cast-iron globe body) and needs no separate body order. Valve DN 150, PN 25, Kvs 320 m³/h, Flange. An impulse tube set (003G13xx/14xx) connects the actuator diaphragm to the pressure tapping. Confirm DN, PN, Kvs and the differential-pressure setting range 0.5–12 bar against the AF-range / PCV data sheet before ordering.
