Features

Corrosion Resistance and Automated Sealing for Fluid Control

✅ Corrosion-Resistant Construction: The valve utilizes a stainless steel body (304/316) for excellent corrosion resistance, making it suitable for both general industrial and food-grade media.

✅ Superior Soft Sealing Performance: Features an NBR or EPDM soft seal ring that is wear-resistant and easy to replace. The design ensures bi-directional sealing and achieves zero leakage under low-pressure differential conditions.

✅ Automated Pneumatic Control: Paired with a reliable pneumatic actuator (AT Series) for quick and accurate 90° rotation, offering automated ON/OFF or adjusting control.

✅ Lightweight Wafer Body: The wafer-type body is compact and lightweight, facilitating easy installation and minimizing the footprint within pipeline systems.

✅ Optimized for Water and Fluid Industries: This valve is ideally suited for various fluid control sectors, including Beer Brewing Equipment, HVAC Water Systems, and Ship Ballast Water Control.
