Operating Mechanism (Drive Mode)
• Manual: Worm gear-operated valves for large diameter or high-pressure systems.
• Pneumatic Actuation: Quick and precise automated operation for systems requiring remote control (e.g., TG091, TG104).
• Electric Actuation: Precise and reliable operation for automated systems, ideal for remote and feedback-controlled environments (e.g., TG084, TG090).
• Hydraulic Actuation: Used for heavy-duty, large diameter, or critical applications requiring smooth and powerful operation (e.g., TG085, TG097).
Materials
• Body Material Options:
o Carbon Steel, Stainless Steel (304, 316, 316L)
o Cast Iron, Ductile Iron
o Alloy Steel, Bronze (for special applications)
• Disc Materials:
o Stainless Steel, Alloy Steel, Cast Iron (based on the application)
• Seat Materials:
o Soft Seals: EPDM, NBR, PTFE for low and medium-pressure applications
o Metal Seals: Stainless Steel, Inconel for high-temperature and high-pressure applications
Certifications
• Compliance: API, ISO 9001, CE, PED certifications for pressure-containing equipment.
• Optional Explosion-Proof Certification: Available for valves operating in hazardous environments, particularly those with electric or pneumatic actuators.
• Quick Shut-Off Valves: Electro-hydraulic or hydraulic actuated valves (e.g., TG085, TG086) are designed for quick shut-off applications requiring precise control in emergency situations.
• Soft and Hard Sealing Options: Soft-sealing butterfly valves provide leak-tight performance in general applications, while hard-sealing valves are ideal for high-temperature, high-pressure systems.
• Multi-Blade and Multi-Layer Designs: Used in specialized industrial applications such as HVAC, these designs allow for more complex flow control.
• Ventilation Systems: Large diameter and ventilation butterfly valves (TG081, TG084) provide efficient control in air flow systems with minimal resistance.
