VIP Pneumatic Coaxial Valve

Both Double Acting and Spring Return VIP valves (either Normally Open or Normally Closed) are available in sizes ranging from 3/8” to 2”. Unidirectional flow. Filtered compressed air, not necessarily lubricated. At temperatures from -20°C to 0°C, use dry air. In case of lubricated air, seal compatible oil must be used. GAS threaded ends as per UNI/ISO 7/1 Rp - DIN 2999 (NPT threads on request) with control fluid connections as per NAMUR interface. Improved fluid dynamics allow minimum pressure losses. VIP valves can be used in any mounting position (horizontal, vertical or oblique).

They can be provided with seals in NBR, FKM or EPDM:
NBR: suitable for air, gas, oils, water etc. FKM: perfectly suitable for most fluid. Unsuitable for steam. EPDM: perfectly suitable for hot water and steam. Unsuitable for mineral products (oils, grease, etc..).

Valve opening and closing can be signalled by means of external magnetic limit switches (to be requested on ordering the valves, as they cannot be assembled afterwards).

Air supply:
3 bar min.- 8 bar max. in Double Acting execution.
4,2 bar min.- 8 bar max. in Spring Return execution.

Pressure: 10 bar max, see diagram
from -20°C to +80°C (NBR);
from -20°C to +150°C (FKM);
from -20°C to +150°C (EPDM).

Vacuum tightness: 740 mm Hg
