Swagelok SS-12NRF12 is a stainless-steel severe-service union-bonnet needle valve designed for precise, controllable flow in demanding process installations. It features a 3/4 in FNPT end connection and a union bonnet that simplifies servicing and isolation without disturbing adjacent tubing. The NRF designation identifies a regulating-stem variant, providing fine adjustment and reliable shutoff under high-pressure, high-integrity systems. Constructed from Swagelok stainless steel, this valve is suited for instrumentation lines and process piping where durable, leak-tight control is required in challenging environments.
