High-pressure Y-type stop valve

Our hydrogenation units also use high-pressure Y-type stop valves; their function is quite simple – to regulate the flow rate of the medium, as well as to shut off the flow. As for its internal structure, it is similar to that of a regular globe valve; it features a pressure-self-sealing valve cover made of 316 material. The connection methods include welding at one end and using flanges at the other end, or welding at both ends. Its advantages include those of a regular shut-off valve; it is also wear-resistant, corrosion-resistant, has good friction resistance, and a long service life. It features a self-sealing structure – the higher the pressure, the tighter the seal, resulting in reduced risk of leakage. As for the process requirements, they all involve high-pressure hydrogenation units; hydrogen exerts hydrogen embrittlement effects at high pressures, and this is extremely dangerous – even a slight leak can lead to an explosion. Therefore, high-pressure Y-type stop valves are used.

I just won a bid for a high-pressure Y-type globe valve; these devices have high standard requirements

The high-pressure hydrogenation projects we are working on now use high-pressure Y-type stop valves, of the pressure-sealing type

Design standards for high-pressure Y-type stop valves: Design and manufacture: ASME 16.34, JB/T3595; Inspection and testing: JB/T3595, MSS SP61. Connection types: Socket welding – ASME B 16.11; Butt welding – ASME B16.25; Flange connection – ASME B 16.5. Technical parameters: Nominal diameter: 3/4”–4”; Nominal pressure: ANSI 150LB–4500LB; Operating temperature: -23–+600 degrees Celsius. Actuators: Manual, electric. Leakage: Zero leakage

High-pressure Y-type stop valves have relatively low flow resistance due to their structural design. Moreover, it is more suitable for manufacturing valves that can withstand high pressure. This type is commonly used for high-pressure valves. The Y-type stop valve from Canadian VELAN features an integrated design that reduces the number of potential leakage points, and it has a large track record of successful installations in China.

Could you explain the direction of the stem of a Y-type stop valve and the direction of fluid flow? Thank you!

We are LVF valves from Italy; this type of Y-shaped stop valve is one of our strong selling points. Please contact me if you are interested. Email: 5065404@qq.com

I haven’t done a wrap for a Y-type stop valve yet T^T

I have doubts regarding the installation of Y-type stop valves, specifically concerning the direction of the valve stem and the direction of fluid flow; I seek detailed explanations from experts

Study*. I just need it, thank you.
