The Schneider Electric GV310R-20B07 is a 3-way mixing globe valve from the VG310R series, sized DN20 with Rp internal thread connections and a bronze body. It carries a PN16 pressure class and a flow coefficient of 6 kvs, with an equal percentage flow characteristic — the standard choice for modulating control in hydronic systems where precise response matters across the operating range.
Rated for water and glycol mixtures up to 60 %, with an operating fluid temperature range of -7 to 100 °C. The 20 mm pipe size and 20 mm body size match standard DN20 piping; the Rp internal thread connection threads directly onto mating male BSP parallel threads. Seat leakage meets Class III (0.1 %) on both A-AB and B-AB ports, which is the typical spec for closed-loop heating and cooling coils where a small leakage is acceptable.
