Diaphragm valve DKDV series

pneumatically-operatedadjustmentshut-off

Pneumatically actuated diaphragm valve with male ends, metric series. Normally Closed function. The DK diaphragm valve is particularly suitable for shutting off and regulating abrasive or dirty fluids. The new internal geometry of the body significantly increases the flow coefficient, reduces pressure drops and allows accurate adjustment over the entire shutter stroke. The DK is extremely compact and very light. The innovative handwheel is equipped with a patented immediate and ergonomic locking device that allows it to be adjusted and locked in any position. The new compact and light piston actuator in PP-GR makes the DK/CP the ideal choice for applications requiring very frequent valve operation and a long valve lifetime. Main features: 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
