J41H-600LB American Standard Stop Valve

Working principle and purpose of the product:

The closing principle of American standard globe valves is to rely on the pressure of the valve stem to tightly fit the sealing surface of the valve disc and the sealing surface of the valve seat, preventing medium flow.

The American standard globe valve is suitable for cutting or connecting pipeline media in various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and power industries with a nominal pressure of PN150LB-600LB and a working temperature of -29~550 ℃.

Product structure characteristics:

1. No friction during opening and closing. This function completely solves the problem of traditional [wiki] valves [/wiki] affecting sealing due to mutual friction between sealing surfaces.

2. Top mounted structure. Valves installed on pipelines can be directly inspected and repaired online, which can effectively reduce device shutdown and reduce costs.

3. Single seat design. Eliminated the problem of abnormal pressure increase in the cavity medium of the valve, which affects the safety of use.

4. Low torque design. The valve stem with a special structural design can be easily opened and closed with just a small handle valve.

5. Wedge shaped sealing structure. The valve is sealed by the mechanical force provided by the valve stem, which presses the ball wedge onto the valve seat, ensuring that the sealing performance of the valve is not affected by changes in pipeline pressure difference. The sealing performance is reliably guaranteed under various working conditions.

6. Self cleaning structure of sealing surface. When the ball tilts away from the valve seat, the fluid in the pipeline passes evenly along the sealing surface of the ball at a 360 ° angle, not only eliminating the local erosion of the valve seat by high-speed fluid, but also flushing away the accumulation on the sealing surface, achieving the purpose of self-cleaning.
