Nadi L65/L66/L67/L68 Two Way Servoassisted

Nadi L65/L66/L67/L68 Two Way Servoassisted Solenoid Valve: Nadi solenoid valves are designed according to European standards and with explosion-proof certificates according to actual “ATEX” 2014/34/UE regulations.

Design, manufacturing method, quality assurance, and tests are carried out by staff, 30 years experienced in advanced solenoid valve production, able to collaborate with customer’s technical departments in order to solve special problems, make feasibility studies for solenoid valves or duty for special applications.

Two-way internal pilot solenoid valve. Drived diaphragm or drived piston type. Suitable for gaseous and liquid media compatible with the (body/seals) material used. Adjustable closing time speed regulator to reduce water hammering available on 1”, 1”¼,1”½, and 2” bodies. Diaphragm seal type (L65/L66) for general purpose or piston type (L67/ L68) used in heavy-duty operation; high-frequency duty cycle. PTFE piston is suitable for media not compatible with the standard elastomers. Forged brass, nickel-plated brass, or stainless steel body (1/2” & 3/4”). Stainless steel internal parts. Stainless steel springs. 360° degrees orientable solenoid. Mountable in any position.
