Both Double Acting and Spring Return VIP valves (either Normally Open or Normally Closed) are available in sizes ranging from 3/8” to 2”.
GAS threaded ends as per EN 10226-1 Rp (Ex ISO 7/1) – DIN 2999 (NPT threads on request) with control fluid connections as per NAMUR interface.
Improved fluid dynamics allow minimum pressure losses. See Flow Pressure Diagram.
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..).
For further information about gas, explosive fluids, material compatibilities etc. please contact our technical department.
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 order phase.
According to 2014/68/EU “PED”.
2014/34/EU ATEX configuration to request at time of order.
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.
