Rotork YT-3300LSN1521S Electro-Pneumatic Valve Positioner, Linear, Single-Acting, Non-Explosion Proof — Pack of 1

Manufacturer: Rotork (Young Tech Co., Ltd. - a Rotork brand)

Overview: The Rotork YT-3300LSN1521S is a sophisticated electro-pneumatic valve positioner from the advanced YT-3300 series, specifically engineered for precise and reliable control of linear, single-acting pneumatic valve actuators. This model accurately translates a standard analogue electrical input signal (e.g., 4-20mA) into a proportional pneumatic output pressure, ensuring superb control and accurate positioning of globe, gate, or diaphragm valves. The YT-3300 series is well-regarded for its exceptional durability, stable operation, and suitability for a wide array of demanding industrial applications. This particular configuration is a non-explosion-proof version, designed for general industrial environments.
