Heavy-duty ball control valves with ENVIPACK stem seal With the series KNR, KNRP (ISO/DIN) and KNAR, KNARP (ASME/ANSI), compact control valves with high flow control accuracy are available to plant operators. In many applications they are a very economical alternative to bellows-type sliding stem valves and rotary plug valves. The ENVIPACK stem sealing, valve body and seat rings are i dentical to those of the shut-off ball valves KN and KNA, as are the selection of material and the pressure/temperature range. Advantages: minimum stocks of spare parts, subsequent conversion from a shut-off...
