The V311T is an internally threaded 3-way globe valve designed for a wide range of heating and cooling applications. The valve uses a crown plug for precise fluid control. The crown plug provides precise fluid control with a rangeability of 5:1 and is of a self cleaning design for reliable operation. Valve size: DN4, G External, Flow capacity, Kvs: 25 m³/h. Constructed and flanged to a PN16 pressure class. ΔPm of maximum 4 Kpa. EPDM seals provide a working temperature range of -2 °C to + 12 °C, the soft seat seal ensures a tight close off with no leakage. 2 mm stroke ensures high controllability, Equal percentage flow characteristic ensures high controllability at low opening degrees. Meets the 214/68/EE, article 4.3 of the PED (Pressure Equipment Directive).
