NSV Electric Ball Valve with Rotork Actuator

NSV Electric Ball Valve with Rotork Actuator 

The NSV electric ball valve features a forged body in A105 or LF2, with a trunnion-mounted design offering double block and bleed (DBB) functionality for service from ambient to cryogenic temperatures. This configuration includes a reduced bore design, balancing high flow capacity with optimized actuation torque.

Available with metal-to-metal or reinforced PTFE seating, it operates across Class 150–2500 (PN16–PN420) on media such as natural gas, steam, LPG, and hydrocarbons. Equipped with a Rotork intelligent electric actuator, it supports remote on/off control, position feedback, and system interlocking which is ideal for oil & gas transmission, LNG terminals, refineries, and energy infrastructure.
