Key Features and Benefits:

1. Full PTFE Encapsulation

Seat & Disc: Virgin PTFE encapsulation eliminates metal contact, resisting 98% sulfuric acid, chlorine, and solvents (pH 0-14).  

2. Heavy-Duty Worm Gear Operation  

High Gear Ratio: Reduces manual torque by 40% vs. lever valves at PN16 pressures.  

Sealed Gearbox: Weatherproof design for outdoor/chemical exposure with visual position indicator.  

3. Lug-Type Structural Integrity

Direct Pipeline Mounting: Threaded lugs enable installation without nuts – ideal for end-of-line service.

Thermal Stress Relief: 3D-machined lugs prevent thread distortion during thermal cycling (-50°C to 200°C).

4. Fire-Safe & Cryogenic Ready

LNG Compatibility: DNV-GL certified for -196°C cryogenic service.  

5. Certified Quality

Compliant with ISO 9001, API 609, and CE, WRAS, UKCA, ACS standards, ensuring global acceptance.  

Rigorous quality control processes, including pressure testing and material inspection.
