Danfoss WVH 1 1/4 in Valve Body for WVS / WVTS Water Regulating Valve

Danfoss WVH 1 1/4 in cast-iron valve body, OEM P/N 016D5032, for the pilot-operated WVS/WVTS 32 water regulating valve. The WVH body is the throttling main valve of the Danfoss modular water-valve system: a WVS pressure pilot (opens on rising pressure) or a WVTS thermostatic pilot (opens on rising temperature) mounts on top to control condenser cooling-water flow. Orifice 32 mm; Kv 12.5 m³/h; port connection G (internal thread), ISO 228-1. Differential pressure range 0.5 – 4 bar; max working pressure 10 bar (145 psig); media temperature -25 °C to 90 °C; neutral media. Cast iron body. Supplied as multi pack (4 pc) including valve body, flange bolts, flange gaskets and pilot-valve screws. Order the matching WVS or WVTS pilot separately.
