Detail Information

Product Name: Y Pattern Pressure Sealed Globe Valve
Design Standard: BS 1873, ASME B16.34
Body Material: ASTM A216 WCB
Size: 3 Inch, DN80
Pressure: Class 1500 LB, PN250

Operation: Handwheel

The pressure seal globe valves are engineered in compliance with BS1873 and ASME B16.34 standards, making them ideal for high-temperature and high-pressure applications, particularly in fossil fuel power plants. Compared to bolted bonnet joint valves, these pressure seal valves offer superior sealing reliability at the bonnet joint, resulting in a more compact, rigid design that reduces maintenance costs in high-temperature, high-pressure environments.
The two medium flow openings are positioned in the same direction, forming a 180° angle. The seat and disc sealing surfaces are overlayed with iron-base alloys, Co-base alloys, or carbide alloys, ensuring long-lasting performance. For larger-sized valves, a main and vice disc design is employed, with medium flowing from the top disc to the bottom disc. This design significantly reduces operational torque and enhances seat tightness, ensuring more reliable sealing performance.
