Specifications: The Class 300 Stainless Steel Globe
Valve, identified as Fig# GL 300SSF10, adheres to several standards including ASME B16.34 for steel globe valves, ASME B16.10 for face-to-face dimensions, ASME B16.5 for end flange dimensions, and API 598 for inspection and testing. The valve is designed with an Outside Screw and Yoke (OS&Y) and features a forged T-head stem, a rising stem, and a non-rising handwheel. It is manufactured in accordance with NACE MR0175 specifications.
Materials: The valve consists of various parts made from specific materials:
- Body: A351-CF8M
- Disc: A182-F316
- Disc Cap: A351-CF8M
- Stem: A276-316
- Gasket: PTFE/316+PTFE
- Bonnet: A351-CF8M
- Bonnet Bolt: A193-B8M
- Nut: A194-8M
- Packing: PTFE
- Gland Flange: A351-CF8
- Stem Nut: A439-D2
- Handwheel: A395-65-45-15
- Yoke: A351-CF8
Dimensions: The valve dimensions vary based on the nominal pipe size (NPS) and class 300Lb flange dimensions. Key dimensions include diameter (d), length (L), height (H), width (W), and weight (WT) in pounds. For example, a 1/2 inch valve has a length of 6 inches, a height of 7.6 inches, and a weight of 8.8 lbs, while a 12 inch valve has a length of 28 inches, a height of 40.63 inches, and a weight of 1373 lbs.
Key Features: The valve is designed for durability and reliability, with materials selected for their resistance to corrosion and wear. The use of PTFE in gaskets and packing ensures a tight seal and reduces the risk of leaks. The rising stem design allows for easy visual indication of valve position.
