Product catalog summary
General Specifications: The VIP pneumatic axial valve is available in double acting (DA) and spring return (SR) versions, with sizes from 3/8” to 2”. It supports unidirectional flow and has threaded ends compliant with GAS UNI/ISO 7/1 Rp - DIN 2999 standards, with optional NPT threads. The valve is designed for minimal pressure loss and can be mounted in any position. Seals are available in NBR, FKM, and EPDM, each suitable for different fluids and conditions.
Control and Operating Media: The control media is filtered compressed air, with a pressure range of 3 to 8 bar for DA and 4.2 to 8 bar for SR versions. The operating media can handle pressures up to 10 bar and temperatures from -20°C to +150°C, depending on the seal material.
Working Principle: The valve operates via piston movement driven by control fluid pressure, independent of the intercepted fluid pressure, allowing for a compact and efficient design with minimal pressure loss.
Valve States: The valve can be closed, open, or in a transitionary state, with transitions lasting less than a second. SR versions default to closed (N.C.) or open (N.O.) positions without control.
Dimensions and Codes: Detailed dimension tables and VIP codes are provided for different configurations and seal materials, including ATEX compliance options.
Components and Materials: The valve components are primarily made of nickel-plated brass, with seals available in NBR, FKM, or EPDM. A material table lists each component's material and treatment.
Accessories: Compatible solenoid valves are described, including a 5/2 NAMUR standard valve and a compact universal micro solenoid valve, with specifications and operational parameters.

Vip - Pneumatic axial valve-1

valvola di intercettazione pneumatica pneumatic axial valve Caratteristiche generali Disponibile nelle versioni doppio effetto “DA” e semplice effetto “SR” (sia normalmente aperto sia normalmente chiuso) con misure da 3/8” a 2”. Flusso unidirezionale. Attacchi filettati GAS UNI/ISO 7/1 Rp - DIN 2999 (a richiesta filetti NPT) con connessioni del fluido di comando secondo interfaccia NAMUR. L’ottimizzazione della fluidodinamica interna ha consentito la realizzazione di un condotto con perdite di carico ridotte al minimo: vedi diagramma portate. Possibilità di utilizzo in qualsiasi posizione di montaggio (orizzontale, verticale, obliqua). Disponibile con guarnizioni NBR, FKM, EPDM: NBR: compatibile con aria, gas, olii, acqua, ecc.. FKM: ottima compatibilità con la maggior parte dei fluidi. Sconsigliato per il vapore. EPDM: ottima compatibilità con acqua calda e vapore. Non compatibile con prodotti minerali (olii, grassi ecc..) Per gas, fluidi esplosivi e maggiori informazioni sulla compatibilità dei materiali si prega di consultare il nostro ufficio tecnico. Possibilità di segnalare l’apertura o chiusura della valvola tramite l’applicazione di finecorsa magnetici esterni (disponibili a richiesta, specificando in fase d’ordine, non essendo possibile l’applicazione a posteriori). Conforme alla direttiva Europea 97/23 EC “PED” - Versione ATEX in conformità alla direttiva 94/9/EC (da richiedere in fase d'ordine) 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 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. 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. 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). According to 97/23 EC “PED” - ATEX version in conformity with directive 94/9/EC (to request at time of order) Fluido di comando: aria compressa filtrata non necessariamente lubrificata; con temperature da -20°C a 0°C usare aria secca. In caso di lubrificazione usare olio compatibile con le guarnizioni impiegate. Pressione di comando: min. 3 bar; max. 8 bar nella versione doppio effetto - min. 4,2 bar; max. 8 bar nelle versioni semplice effetto. Fluido intercettato: Pressione: max. 10 bar, vedere diagramma Temperatura: da -20°C a +80°C (NBR); da -20°C a +150°C (FKM); da -20°C a +150°C (EPDM). Tenuta al vuoto: 740 mm Hg 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 bar max. in Double Acting execution. 4,2 bar min.- 8 bar max. in Spring Return execution. Operating media: Pressure: 10 bar max, see diagram Temperature: 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

Vip - Pneumatic axial valve-2

Principio di funzionamento La valvola di intercettazione pneumatica VIP (di esclusivo brevetto OMAL) é, a tutti gli effetti, una valvola automatica che raggruppa, in un unico dispositivo, sia il meccanismo di intercettazione (tra il condotto C-D) che quello di comando (A-B). Il principio di funzionamento si basa sul movimento interno di un pistone dovuto alla pressione del fluido di comando. Il pistone, esaurita la sua corsa (VIP é una valvola on/off ), preme o si stacca dalla guarnizione del seggio di tenuta, consentendo o impedendo il passaggio del liquido intercettato. Dato che la tenuta é...
