Easytork Namur Trip Valve (NTV)

ECAs and EVAs will work with any positioner in the market. Regardless of double-acting or fail-safe setup, user must use a double-acting positioner. Installing or not installing Easytork’s NAMUR Trip Valve (“NTV”) with a double-acting positioner determines what function (fail-safe, in CW or CCW, or double-acting) the actuator has. Any 4-20ma or 3-15 psi positioner in the market works with the system. NTV removes integration complexity between actuator, positioner and air reservoir. In most instances, set-up is significantly easier and more economical than spring-return actuators. With Easytork’s built-in air reservoirs, system integrator only needs to connect signal source to positioner and supply air to Easytork’s system.

Fail-Safe: Installing an NTV on an Easytork actuator allows the actuator to fail-safe.
