Detailed Selling Lead Description
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 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.)
Information about material compatibilities can be found in the specific table.
For further information about gas, explosive fluids 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).
