Product Overview
The GF 343T Type PVC-U/EPDM RP Threaded 3-Way Ball Valve (RP1/2" DN15) is engineered for precise fluid control in industrial automation systems. Constructed with a corrosion-resistant PVC-U body and EPDM seals, it ensures durability in harsh chemical environments. The T-port design enables efficient flow diversion or mixing across three orthogonal pipelines, making it ideal for applications requiring dynamic routing of liquids or slurries. Rated for PN16 pressure (16 bar at 20°C), this valve features RP1/2" threaded connections for secure, leak-free installations. Its compact, lightweight design (1.2–1.5 kg) and manual operation with a lockable handle simplify maintenance and integration into existing setups.
Technical Specifications & Features
This valve operates within a temperature range of -10°C to 60°C and meets ISO 9001, NSF 61, and FDA compliance standards. The four-seat PTFE-lined ball design ensures bidirectional flow control and reduces operational torque, while dual EPDM stem seals prevent leakage. With a full-port diameter of DN15 (1/2"), it maintains minimal pressure drop and high flow capacity (CV 4.6). Optional accessories include ISO 5211 actuator mounts for automated control. The modular construction supports customization with limit switches or handle extensions, enhancing adaptability to diverse industrial needs.
Applications & Advantages
Suitable for water treatment, chemical processing, and food industries, the GF 343T valve excels in managing non-corrosive to mildly corrosive media. Its NSF certification makes it safe for potable water systems, while the RP threading ensures compatibility with standard pipe fittings. The union nut locking mechanism prevents loosening under vibration, and the ergonomic handle design allows easy operation. Backed by GF’s 10-year warranty and global technical support, this valve combines reliability, cost efficiency, and sustainability, aligning with eco-friendly practices through its PVC-U material and energy-efficient installation.
