Product Introduction

The PT Series Pneumatic Flanged Center-Line Butterfly Valve by Autorun is a robust, versatile flow control solution built for reliability in industrial water, gas, and light oil applications. Designed with a center-line disc aligned perfectly with the stem axis, it delivers low-torque operation and bi-directional sealing, making it ideal for both shut-off and modulating duties.

The valve's flanged body ensures secure, leak-free installation in pipelines up to DN1200, while its cast iron body paired with a CF8 stainless steel disc offers excellent corrosion resistance and structural integrity. The EPDM seat provides tight shut-off even at low pressures, ensuring consistent performance across PN10/PN16 pressure ratings.

Paired with Autorun's high-efficiency aluminum pneumatic actuator (available in double-acting or spring-return configurations), it delivers fast, precise 90° rotation with minimal maintenance. The ISO 5211 direct-mount design eliminates the need for extra brackets, reducing installation complexity and potential leak points.

Compact yet durable, this butterfly valve thrives in HVAC, water treatment, and general process industries, where quick response and long service life are critical. Its balanced design minimizes pressure drop, while the actuator's weather-resistant IP67 build ensures stable operation in harsh environments.
