1) Flange type: 21; flange design: B (see "Flange types", page 72)
2) Suitable for medium temperatures up to 130 °C
3) Valve characteristics for pressure compensated valves for kvs value 100 m3/h from 70 % stroke, kvs value 40,160 and 250 m3/h from 80 % stroke and kvs value 63 m3/h from 90 % stroke is optimized for maximum volumetric flow.
Fluids and Steam
Applications with steam
Valves of the product lines VVF43..K and VVF53..K are regarding flow direction optimized for fluids and steam. This results in combination with electrohydraulic actuators of the product lines SKD.., SKB.. und SKC.. with significantly higher closing pressures Δps and higher maximum differential pressures Δpmax.
In individual cases the kVS value is reduced and it has to be assured from the system side, when the system is starting up that the maximum differential pressure Δpmax is not exceeded so that the actuator can reliably open the valve.
