Product Description
Product Overview

The CF8 Pneumatic Diaphragm Three-Way Control Valve is a precision industrial valve designed for regulating fluid flow in demanding process control applications. Available in both combined flow (SZJHQ) and split flow (SZJHX) configurations, this valve features cylindrical thin-walled window-shaped valve core guidance for superior performance.

Key Applications

Ideal for maintaining precise control of pressure, flow rate, temperature, and liquid levels in industrial processes involving gases, liquids, and other media. Suitable for dividing fluid streams or merging multiple flows into a single stream.
