Product Detail

High-pressure welded angle globe valve J64Y-64 is a special valve designed for high temperature and high pressure working conditions. It is widely used in steam, water, gas and other media control systems in power plants, chemical plants, petrochemicals and other fields. Its design adopts a welded angle structure, which has high-strength sealing performance and resistance to extreme working conditions. It is especially suitable for complex installation scenarios where the pipeline direction needs to be turned 90°.

Product Features

1. Valve body and connection form: The valve body adopts an angle structure, and the inlet and outlet channels are arranged at a 90° right angle, which reduces the number of fluid turns and local resistance losses. The connection form is a flange connection to ensure rigid docking with the pipeline system and avoid leakage risks.

2. Valve disc and sealing components: The valve disc is a plug-shaped design, and the sealing surface adopts a flat or conical structure. The opening and closing are achieved through the linear motion of the valve stem, and the sealing performance is excellent. Equipped with a bellows sealing structure to eliminate the risk of stuffing box leakage, it is suitable for toxic and corrosive media.

3. Valve stem and drive mode: The valve stem adopts a rising stem lifting type, the handwheel is separated from the valve stem, the opening and closing status is visualized, and remote operation expansion is supported.

Technical Features

- Nominal pressure range: 16.0~32.0 MPa, covering the needs of ultra-high pressure pipelines.
- Applicable temperature: -29℃~+425℃, the valve body material is ASTM A216 WCB cast steel or austenitic stainless steel, and it maintains stable mechanical properties at high temperatures.
- Double seal design: The valve disc and the valve seat adopt carbide sealing pair, combined with graphite packing to ensure zero leakage.
- Self-tightening seal structure: The higher the medium pressure, the tighter the sealing surface fits, especially suitable for high-pressure steam systems.
- The full open/full close stroke is short, the opening and closing time is ≤10 seconds (manual operation), and the medium can be quickly cut off under emergency conditions.
- The valve cover bolt connection design supports online maintenance, and the packing or seal can be replaced without disassembling the valve.
