American Standard Shut-off Valve

The oxygen specific shut-off valve is made of high-quality silicon brass or stainless steel casting, which has the advantages of high mechanical strength, wear resistance, and good safety. Used on oxygen pipelines, it has effective explosion-proof and flame-retardant properties, eliminating unsafe factors on oxygen pipelines.

American Standard Shut-off Valve Product Introduction:

The ANSI-standard shut-off valve is suitable for pipelines in various industrial applications—such as petroleum, chemical, pharmaceutical, fertilizer, and power industries—operating under nominal pressures ranging from 150 LB to 2500 LB and temperatures between -29°C and 550°C, enabling the cutting off or connecting of fluid media. Available actuation options include manual, gear-driven, electric, and pneumatic operation.

American Standard Globe Valve, ANSI American Standard Globe Valve: Key Structural Features

1. The product’s design and manufacturing comply with international standards such as the U.S. National Standard ANSI B16.34 and the U.S. BS 1873.
2. The valve body features a sleek, barrel-shaped or streamlined design for an aesthetically pleasing appearance. It has a straight-through flow path, ensuring minimal fluid resistance.
3. The closing member (gate flap) uses a conical sealing surface against the valve seat, resulting in low closing force, excellent erosion resistance, and reliable sealing performance.
4. The valve seat is a replaceable type, allowing for flexible combinations with sealing surface materials tailored to meet specific operating conditions and extend service life.
5. Large-caliber, high-pressure shut-off valves use a rising stem design for the valve stem transmission, depending on the required closing force, and are equipped with roller-bearing mechanisms paired with impact-type handwheels to reduce the closing effort.
6. The materials for the main components, internal parts, fillers, and fasteners can be reasonably combined according to user requirements or actual operating conditions.
