Description

GENERAL FEATURES:

• 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.

• P MAX 40 bar (580 psi) in indicated direction.

• GAS threaded ends as per EN 10226-1 Rp (Ex ISO 7/1) – DIN 2999 ; NPT.

• Threaded connections for air supply system (NAMUR adapter plate on request).

• Improved fluid dynamics allow minimum pressure losses.

• VIP valves can be used in any mounting position (horizontal, vertical or angled).

• Seat PTFE + GF.

• Lips seals and o-ring:

– NBR: suitable for air, gaseous fluids, oils, water etc.

– FKM: perfectly suitable for most fluid. Unsuitable for steam.

– EPDM: perfectly suitable for hot water. Unsuitable for mineral products (oils, grease, etc.).

• Possibility to check open / close valve position thanks to inductive limit switches (magnetic contact) available on request. Internal magnet needs to be requested at VIP EVO order phase.

• According to 2014/68/EU “PED”.

• 2014/34/EU ATEX configuration available upon request at time of order.

• Vacuum tightness: leack rate <5·10-5 mbar·l/s (Value less than 2g of air at room temperature per year).

CONTROL MEDIA:

• Filtered compressed air, not necessarily lubricated; according to UNI EN 15714-3: 2009.

• In case of lubricated air, seal compatible oil must be used.
