Gaoshan Valve – RJ41F-25 Gas Globe Valve
Model: RJ41F-25 | Pressure Class: PN25 | Size Range: DN25~DN200
RJ41F-25 gas globe valve is specially designed for pipelines requiring strict anti-leakage and fire safety, suitable for liquefied petroleum gas, natural gas, water, and oil products. It features a fire-safe structure and self-compensating packing, ensuring reliable shut-off performance for critical gas systems.
✅ Core Strengths
- Anti-Leak & Fire-Safe Design: Features fire-resistant structure; even if soft sealing material burns out, the metal seal still works, ensuring pipeline safety.
- Self-Compensating PTFE Packing: Elastic PTFE packing provides self-sealing performance for zero external leakage under varying conditions.
- Reliable Dynamic Sealing: Large-diameter seal ring or inverted seal structure ensures safe and reliable sealing performance during operation.
- Corrosion & Dust Protection: Equipped with a stem dust-proof ring to protect internal components from external erosion.
- Durable Barrel-Style Body: High-strength barrel-shaped body design, compact structure, and beautiful appearance.
- Low-Torque Operation: Non-forced dynamic sealing structure reduces opening/closing torque for smooth handwheel operation.
