1. Rugged Lug Type Valve Body Design:
Pipe Stress Elimination: Threaded inserts allow direct bolting to pipeline flanges without through-bolts, preventing distortion in high-vibration or thermal expansion environments.
Dead-End Service Ready: Secures pipe ends without additional supports.
Zero-Pipeline-Damage: 304/316 stainless steel lugs distribute load evenly, protecting FRP or aging pipelines.
2. Triple-Sealed Resilient Rubber Seat
EPDM/NBR Compound: Resists ozone, chlorinated water (≤5 ppm), and temperature swings (-15°C to 120°C / 5°F to 250°F).
Zero-Leakage Guarantee:Meet or Exceeds AWWA C504 Class IV sealing.
Self-Compensating Design: Automatically adjusts to disc wear and minor pipe misalignment. 3. High Torque Industrial Gearbox
15:1 to 100:1 Ratio Options, Weatherproof Housing, Position Indicators.
