Options: Special threads, special flanges, NO function, damping, limit switches, manual override, approvals, mounting, tension special, M 12 x 1 plug, terminal box.
With a fine throttle on the pilot valve you can adjust the switching times according to your needs. It is possible to determine switching delays of up to three seconds when opening and closing. This allows avoid hydraulic pressure shocks in piping systems. Due to their unique coaxial construction, most valves operate up to 3 bar control air pressure, while air consumption per shaft is partially only 1/10 of the value of well-known competitors’ products. Using coax valves minimizes the consumption of expensive compressor air , therefore these valves are very energy efficient .
Thanks to their immense switching power, valves with external control can be equipped with additional dirt scrapers . These can also optionally be suitable for the use of viscous or abrasive media , eg. eg, ceramic slip, glue, glue, stain or coolant. The valves of this series can be used in the 1 ATEX / category 2 zone.
Valves with external control are available in a nominal diameter of 8 to 250 mm . The pressure range is from vacuum pressure to a medium pressure of 100 bar . Valve seat tightness is ensured with the control air or hydraulic system connected up to the full pressure level, according to DIN 12266 – regardless of whether the valves operate in the preferred or opposite direction. With the control air or hydraulic system switched off, the sealing of the seat in the opposite direction amounts to a maximum of 16 bar. The technical details can be consulted in the corresponding technical sheets. The amplitude of the flow factor (KV value) ranges from 2.5 to 650 m³ / h . Depending on the nominal diameter, the valves are available in sleeve, flange or special version.
