برند:
KSB
مشخصات:
Service-friendly control valve to DIN/EN with flanged ends, either with linear or equal-percentage control characteristic at Kvs values of 0.1 to 630 m³/h and closing pressures of up to 40 bar; all internal parts are easy to replace without special tools, including the reversible seat; noise level reduced by standard two-stage pressure reduction combining a parabolic plug and multi-hole cage; with electric actuator.
Benefits
Two-stage pressure reduction already integrated as standard to reduce noise emission
Optional anti-cavitation design combines supporting cage and perforated plug
Easy to adjust to specific control tasks by selecting from various valve disc design (equal-percentage or linear) / seat diameter combinations
Available with two types of stem seal: maintenance-free PTFE V-packing (< 250 °C) or adjustable graphite gland packing (450 °C)
Electric actuator with parameterisable actuation: continuous-action or 3-point (Open/Stop/Closed); integration in a process control system via 0/2-10 V or 0/4-20 mA signal; available in various sizes up to 25 kN
Easy to service: The valve trim can be dismantled without any special tools by unscrewing the bonnet bolts.
Internal parts made of high-grade stainless steel (1.4571) for long service life and high chemical resistance
Risk of leakage minimised by fully confined cover gasket
