Product Description
Danfoss KDC 150 D 2 multifunctional compressor valve (pressure control valve), code 148G3602. Angle-way valve with butt-weld connections to EN 10220, nominal size 150 mm (6 in), for industrial refrigeration compressor packages. The KDC controls the compressor discharge pressure to ensure a fast build-up of pressure and lubrication (oil) pressure at start-up, and simultaneously acts as a check valve in the compressor discharge line to prevent reverse flow when the compressor stops. The valve is force-controlled: it opens when the pressure downstream (oil separator / discharge side) rises to 2 bar (29 psi) above the suction pressure, at which point the spring is compressed and the cone lifts. This 2 bar spring setting suits high-pressure compressors. Housing and bonnet are low-temperature steel with stainless-steel bolts; the valve is mounted vertically with the cone downward and carries a threaded NPT 1/4 in pilot-line connection on the bonnet. Maximum working pressure 40 bar (580 psig); media temperature range -50 °C to 150 °C (-58 °F to 302 °F). Flow coefficient Kv 509 m³/h (Cv 590 gal/min) fully open. Suitable for HCFC / HFC, R717 (ammonia) and R744 (CO2) refrigerants. PED category III. CE marked.

Compatibility & Fitment
Danfoss KDC 150 D 2 is selected by compressor package: match nominal size (150 mm (6 in)), weld-end standard (EN 10220; letter D = EN 10220, letter A = ASME B36.10M Schedule 40), and the opening differential-pressure spring (2 bar — use 0.5 bar for low-pressure/booster compressors and 2 bar for standard high-pressure compressors). This is the HCFC/HFC/R717/R744 version. KDC and GVD share internal parts and servicing; seal kits, spring kits and bonnet/housing spares are available separately under the KDC/GVD spare-part codes.
