Diaphragm valve DKOAC/CP

pneumatically-operatedshut-offfor chemicals

High visibility graduated optical position indicator protected by a transparent cap with a seal O-Ring. Compact and light piston 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 finishing 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 seal 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 installation in confined spaces: compressed air inlets with G 1/4” threaded adjustable connections to enable alignment with the piping. PPGR connections prevent any risk of corrosion.
