คลาส Q47-300LBP 300 CF8 ฟอร์จ 2 ชิ้นโลหะนั่งบอลวาล์วคงที่
คลาส Q47-300LBP 300 CF8 Forged 2PCS Metal Seated fixed ball valve Constructed from CF8 stainless steel, this valve offers excellent corrosion resistance and strength, making it suitable for harsh environments.
The two-piece design ensures easy maintenance and durability, while the metal-seated construction provides a tight, reliable seal, even under high temperatures and abrasive conditions. The fixed ball valve ball enhances stability and reduces operational torque, ensuring smooth and efficient performance.
It adopts a two-piece forged stainless steel body, metal-to-metal sealing, and a fixed ball valve ball design that ensures stable operation, low torque, and tight shut-off. Built to API 6D / ASME B16.34 standards, this valve is engineered for durability, safety, and minimal maintenance, making it ideal for oil & แก๊ส, ปิโตรเคมี, power generation, and marine industries.

คลาส Q47-300LBP 300 CF8 ฟอร์จ 2 ชิ้นโลหะนั่งบอลวาล์วคงที่ Key Features
2-Piece Forged Body
The two-piece bolted body provides ease of disassembly and maintenance while maintaining structural integrity under pressure.
Trunnion-Mounted Ball Design
The ball is anchored by trunnions, reducing seat wear and operational torque. This design ensures reliable sealing in large-diameter and high-pressure applications.
Metal-to-Metal Seat
Hardened metal seats (Stellite, Tungsten Carbide, or Chrome coating options) provide superior resistance to abrasion, erosion, and high-temperature service.
Fire-Safe & Anti-Static Design
Complies with API 607 / ISO 10497 fire-safe standards and includes anti-static grounding for enhanced operational safety.
Double Block and Bleed (DBB) Function
Optional DBB configuration allows isolation and venting between upstream and downstream sides for improved safety and testing convenience.
