DATA SHEETUSER MANUALVIDEO
• 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
• Light and compact piston actuator in PP-GR, ideal for heavy-duty applications in chemically aggressive environments
• High performance internal components: piston in high strength IXEF® with high quality surface finish and Stem in stainless steel with double 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
• CDSA (Circular Diaphragm Sealing Angle) system that, thanks to the uniform distribution of shutter pressure on the diaphragm seal, offers the following advantages:
- reduction in the tightening torque of the screws fixing the actuator to the valve body
- reduced mechanical stress on all valve components (actuator, body and diaphragm)
- easy to clean valve interior
- low risk of the accumulation of deposits, contamination or damage to the diaphragm due to crystallisation
MAIN FEATURES: - High visibility optical position indicator protected by a transparent cover with O-Ring
- Light and compact piston actuator in PP-GR, ideal for heavy-duty applications in chemically aggressive environments with a diaphragm perimeter containment system that ensures the perfect compression of the rubber without any lateral expansion
- Piston in high strength IXEF®. The high quality finish of the external surface guarantees perfect slidability over the seal and ensures a long working life without any actuator maintenance
- High strength stainless steel stem with double O-Ring
- Floating pin connection between the actuator stem and diaphragm to prevent concentrated loads, improve the seal and extend its lifetime
- Actuator equipped with 6 independent cartridge springs arranged radially to uniformly distribute the load on the piston
- Dual function main gasket.
- Piston seal: the gasket does not move but sits securely on the actuator cylinder instead of the piston.
- External seal: The gasket positioned above the threaded joint between the bonnet and cylinder ensures that the coupling is not stressed by the pressure inside the actuator
- Easy to install, even in confined spaces: compressed air inlets with G 1/4” threaded adjustable connections to enable alignment with the piping
- 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 inextremely sensitive and precise adjustment along the entire stroke of the shutter
