Piston valve DKB/CP

pneumatically-operatedfor controlfor water

Pneumatically actuated diaphragm valve with male ends, metric series Normally Closed function. The new DKB/CP diaphragm valve is the proper solution for non-severe operating conditions that, however, require reliability and a long working life. The new internal geometry of the body optimises the fluid dynamic efficiency by increasing the flow rate and ensuring an optimum linearity of the flow adjustment curve. The DKB/CP is extremely compact and very light. The new DKB/CP diaphragm valve has a piston actuator in PP-GR with a simplified design, ensuring essential performance. Main features: 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 4 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.
