Adqvalve RC200 High Temperature Butterfly Cut‑off Valve Product Leaflet

About this manual

The Adqvalve RC200 series is a high‑temperature butterfly cut‑off valve designed for service up to 400 °C (and up to <800 °C in special applications). It features a three‑eccentric sealing concept with slanted conical seats that provides ANSI VI zero‑leakage performance and reliable operation in harsh environments.

The series includes pneumatic and hydraulic quarter‑turn actuators (RC‑DA double‑acting and RC‑SR spring‑return) that operate from –45 °C to 150 °C, comply with DIN3337/ISO5211 and VDI/VDE3845 (Namur) standards, and offer low‑friction, high‑torque output for fast, safe valve actuation. This manual is written in Chinese.
