PVC diaphragm valve | DK series DN 15-65 | FIP

• Connection system for solvent weld, threaded and 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
• Internal components in metal, totally isolated from the fluid and external environment
• Modularity of the range: only 2 handwheel and 4 diaphragm and bonnet sizes for 7 different valve sizes
• Non-rising handwheel that stays at the same height during rotation, equipped with a graduated optical indicator protected by a transparent PVC cap with seal O-Ring
• Bonnet fastening screws in AISI 316 steel protected against the external environment by PE plugs. Absence of metal parts exposed to the external environment to prevent any risk of corrosion
• 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.
• CDSA (Circular Diaphragm Sealing Angle) system that, thanks to the uniform distribution of shutter pressure on the diaphragm seal, offers the following advantages:
– operating torque reduction
– reduced mechanical stress on all valve components (actuator, body and diaphragm)
– low risk of the accumulation of deposits, contamination or damage to the diaphragm due to crystallisation
– easy to clean valve interior

MAIN FEATURES:

• High visibility graduated optical position indicator protected by a transparent cap with seal O-Ring
• Customisation plate: the customisation lets you identify the valve on the system according to specific needs
• DIALOCK^® SYSTEM: innovative handwheel with a patented immediate and ergonomic operating locking device that allows it to be adjusted and locked in over 300 positions
• Handwheel and bonnet in high mechanical strength and chemically resistant PP-GR, providing full protection by isolating all internal metal parts from contact with external agents
• Floating pin connection between the control screw and diaphragm to prevent concentrated loads, improve the seal and extend its lifetime
• New design of valve body interior: substantially increased flow coefficient and reduced pressure drop. The degree of efficiency reached has also enabled the size and weight of the valve to be reduced
• Adjustment linearity: the internal profiles of the valve also greatly improve its characteristic curve, resulting in extremely sensitive and precise adjustment along the entire stroke of the shutter
• Valve anchoring bracket integrated in the body, with threaded metal inserts allowing simple panel or wall mounting using the PMDK mounting plate (supplied as an accessory)
