VMOM - Valvola a membrana DN 80÷100
Valvola a membrana con corpo flangiato monolitico foratura EN/ISO/DIN PN10/16. Scartamento secondo EN 558-1.
La VM è particolarmente adatta per regolazione e intercettazione di fluidi abrasivi o contenenti impurità. Il comando a volantino e la tenuta a membrana consentono una precisa ed efficace regolazione e riducono al minimo i rischi di colpo d’ariete.
Caratteristiche principali:
- Handwheel in (PA-GR) with high mechanical strength and ergonomic grip for optimum manageability
- Metal optical position indicator supplied as standard
- Full protection bonnet in PP-GR Internal circular and symmetrical diaphragm sealing area
- Diaphragm available in EPDM, FPM, PTFE (NBR on request) and easy to replace
- Threaded metal inserts for anchoring the valve
- New valve body internal design: substantially higher flow coefficient resulting in lower pressure drops. Optimised adjustment curve for effective and precise flow rate regulation

- Connection system for solvent welding and for flanged joints
- Optimised fluid dynamic design: maximum output flow rate thanks to the optimised efficiency of the fluid dynamics that characterise the new internal geometry of the body
- Handwheel that stays at the same height during rotation, with internal bearing to minimise friction and operating torque
- Standard optical indicator
- Internal operating components in metal totally isolated from the conveyed fluid
- Bonnet fastening screws in STAINLESS steel protected against the external environment by PE plugs
- New flanged bodies: the new bodies, characterised by a monolithic flanged structure, are available in PVC-U, PVC-C, PP-H and PVDF. This design, free from body and flange joints, greatly reduces mechanical stress and increases system performance
