1. Internal diameter equal to the diameter of the pipe Optimised geometry to maximise flow rate
2. Pneumatic actuator integrated in the valve Space saving (-60%) and reduced costs compared to an automated valve
3. Piston with chemical nickel plating (20-25 micron) Lower wear of the seals due to the increase of the surface hardness (400-550 HV)
4. Lip seals Less wear of the seal comparing with an o-ring
Several seal materials available Maximum compatibility with different types of fluids depending by the seals used No external moving parts Maximum safety Easy mounting
Long life time granted Lifetime 10 times longer than a ball valve with with reduced maintenance costs
100% in-house manufacturing process technology Maximum control and accuracy in all the stages of the manufacturing process
Less Air consumption 80% less air consumption compared to an actuated valve with SR pneumatic actuator therefore less load on the compressor or the possibility of using a smaller compressor's size.
ATEX Certificate Installation is allowed in a potential explosive environment PED Certificate Full compliance with European Safety Standards for Pressure Equipment
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. • GAS threaded ends as per EN 10226-1 Rp (ISO 7/1) - DIN 2999 (NPT threads on request) with control fluid connections as per NAMUR interface (optional). • 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, 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 order phase. • Leackage rate class VI according to IEC 60534-4 (ANSI-FCI 70-2 class VI). • According to 2014/68/EU “PED”. • 2014/34/EU ATEX configuration to request at time of order.
CONTROL MEDIA: • 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. • Air supply: 3 bar min.- 8.5 bar max. in Double Acting execution. 4,2 bar min.- 8.5 bar max. in Spring Return execution.
OPERATING MEDIA: • Pressure: 10 bar max, see diagram. • Temperature: - NBR (also version with magnet): from -20°C (-4°F) a +80°C (176°F) - EPDM and FKM without magnet: from -20°C (-4°F) a +150°C (302°F) - EPDM and FKM with magnet: from -20°C (-4°F) a +90°C (194°F) • Vacuum tightness: 97% vacum (about 30 mbar absolut, -980 mbarg). Leackage rate <10-6 mbar·l/s (Value less than 2g of air at room temperature per year).

Working principle A VIP valve (patented by OMAL exclusively) is a proper automatic valve embodying both interception device (between pipe C-D) and control device (A-B). It works thanks to the internal movement of a piston supplied with air. At the end of its stroke (a VIP valve is an ON/OFF valve), the piston presses on the seat seal or moves away from it letting the intercepted fluid flow or stopping it from flowing. As the seat is perfectly tight and the intercepted fluid pressures discharge on it, the pressure necessary to move the piston is completely independent of the fluid pressure. As a result OMAL has been able to design a light space saving and lasting valve. Its full bore and its improved internal dynamics allow minimum pressure losses, too.
Closed valve Supplying the hole “A” with air (the hole “B” must be discharging) at the end of its stroke the piston presses on the seat seal: the valve is closed. As in Spring Return N.C. executions the spring is in “A”, if there is no control, the piston will touch the seat seal: therefore, the preferable position is the closed one.
Transitionary phase During the transitionary phase (the picture shows the opening transition in a Double Acting execution), one of the two holes is supplied. The piston moves axially changing the previous closed or open state. In Spring Return N.C. executions, the closing is caused by the spring (if there is no control). In Spring Return N.O. executions, the opening is caused by the spring (if there is no control). Both opening and closing transitionary phases last less than a second.
Opened valve Supplying the hole “B” with air (the hole “A” must be discharging) at the end of its stroke the piston is at maximum distance from the seat seal: the valve is open. As in Spring Return N.O. executions the spring is in “B”, if there is no control, the piston will be away from the seat seal: therefore, the preferable position is the open one.

LIMIT SWITCH
VIP can be provided with inductive limit switch (magnetic contact) and signal LED. Limit switches can be easily mounted in the integrated slots and fixed with a screw. Since the magnets are situated inside the valve, they must be mounted while assembling the VIP and not afterwards. For this reason, in case needed, magnet must be requested at VIP order phase. The maximum fluid temperature must be lower than the maximum temperature supported by the limit switch.
