Aprašymas
The Venta V211 is a 2-way flanged globe valve designed for a wide range of heating and cooling applications. The valve uses a crown plug for precise fluid control. Nodular iron construction provides a long life and high corrosion resistance. The crown plug provides precise fluid control with a rangeability of 50:1 and is of a self cleaning design for reliable operation. Valve size: DN15, Flow capacity, Kvs: 1.6 m³/h. Constructed and flanged to a PN16 pressure class. ΔPm of 400 Kpa. EPDM seals provide a working temperature range of -20 °C to + 120 °C, the soft seat seal ensures a tight close off with no leakage. 20 mm stroke ensures high controllability, Equal percentage flow characteristic ensures high controllability at low opening degrees. Meets the 2014/68/EE, article 4.3 of the PED (Pressure Equipment Directive). PN16 flanges have fibre gaskets bonded to the flange face. The flange face has a design that accommodates that flexes to allow small mis alignment in the pipes. Valve Length (between flanges) is 130 mm, height is 164.5 mm, width 95 mm, Weight is 2.1 Kg. A stem heater is available as an accessory for use on media temperature below 0 °C. High Controllability and long life.
