Bidirectional Bubble-Tight Zero-Leakage Sealing
This series provides bidirectional bubble-tight zero-leakage sealing, making it suitable for applications requiring shutoff performance in both directions.
Multiple Seat Material Options
TFM 1600 is provided as standard, with optional Tek-Fil, PEEK, UHMWPE, RPTFE, and metal seat materials available to suit different media and operating conditions.
Continuous Preloaded Stem Packing Design
Models from NPS 1/4 to 2 in feature self-adjusting, continuously preloaded stem packing with Belleville washers, while 3 in and 4 in models use externally continuously preloaded packing.
Multiple End Connections and Port Configurations
Available end connections include NPT threaded, socket weld, butt weld, and Class 600 flanged options, with full-port and standard-port versions available.
Installation & maintenance notes
Verify Operating Conditions and Valve Configuration Before Commissioning
Before installation and commissioning, verify that the actual media, pressure, and temperature conditions comply with the specific configuration and material compatibility range of the selected Triad valve. In particular, confirm that the seat and sealing materials are suitable for the operating conditions. The maximum allowable operating pressure is 2200 psi CWP(151 Bar), and the temperature range is -46°C to 287°C. Seat materials can be selected according to the configuration.
FAQ
How does the Triad Series three-piece ball valve work?
The Triad Series uses a three-piece construction. Its self-adjusting stem packing design provides bidirectional sealing, while sealing between the ball and seat is achieved through soft seats, metal sealing, and a V-port ball, maintaining stable flow control under high-pressure and high-temperature conditions.
What key parameters should be considered when selecting the Triad Series?
Consider the size range, body material, temperature and pressure limits, stem material, seat material, leakage class, and end connection type to match the process media, temperature, pressure, and installation space. Specific configurations must be confirmed based on the actual model and application conditions.
What seat materials are available for this series, and is it suitable for corrosive media?
The standard seat is TFM 1600, with optional Tek-Fil, PEEK, UHMWPE, RPTFE, metal seats, cavity fillers, and other materials. Some materials provide compatibility with corrosive media and low torque; however, suitability must be confirmed based on actual operating conditions and media.
What are the key safety design features of the Triad Series?
Features include bubble-tight sealing, externally live-loaded packing, Belleville washer compensation for environmental changes, dual body and stem packing, and an anti-static grounding device to enhance leak-tightness and safety. Specific configurations vary by model.
How does the Triad Series achieve maintenance performance and long-term reliability?
Self-adjusting stem packing, optional fire-safe trim, anti-static protection, and durable stem and material combinations enable maintenance-free or low-maintenance operation in high-cycle and severe-service conditions. Specific maintenance plans must be confirmed based on the actual model and application conditions.
