The VG310 is a high pressure (PN16) 3-way flanged globe valve for a wide range of heating and cooling applications. The valve use a stainless steel plug for high close off pressures with a low actuator force. Stainless Steel plug and seat provides a high pressure differential capability and a low leakage. The crown plug provides precise fluid control with a rangeability of 100:1 and is of a self cleaning design for reliable operation. Valve size: DN50, Rp 2 thread, Flow capacity, Kvs: 35 m³/h. Constructed and flanged to a PN16 pressure class. PTFE Seals provide a working temperature range of -7 °C to 137 °C. 11 mm stroke ensures high controllability, Equal percentage flow characteristic ensures high controllability at low opening degrees.
