Vacuum environment simulation In the thermal vacuum test, the first step is to simulate the vacuum environment of space. When spacecraft operate in space, there is almost no air around them, meaning they are in a high vacuum state. To simulate this environment on the ground, a vacuum system is used, including vacuum pumps, gas condensers, and pressure sensors, etc. The gas inside the test chamber is evacuated to make the internal pressure approach the vacuum state. Usually, the vacuum requirement of the thermal vacuum test is better than 6.5x10^-3 Pa to ensure that the simulated vacuum environment is close enough to the real space environment.If you need more models about our test equipment, please reference our ： https://www.chamber-testing.com/ Temperature cycling simulation In space, spacecraft undergo significant temperature changes because they are exposed to solar radiation and cosmic darkness. The thermal vacuum test simulates these temperature cycles through heating systems and cooling systems. The heating system can use resistance wires, radiation heaters, or high-frequency heaters, etc., by controlling the current and voltage of the heating elements to regulate the temperature. The cooling system may use low-temperature media such as liquid ammonia. During the test, the spacecraft is heated to a high temperature (for example, +65°C) and cooled to a low temperature (for example, -35°C), and cycles between these extreme temperatures to test its performance under temperature changes.

Flange Swing Check Valve is a specific and widely used type of Check Valve. Its primary function is to automatically prevent the reverse flow of media in a pipeline system, allowing flow in only one direction.Its core mechanism features a disc (or flap) that swings on a hinge or trunnion. Under forward flow pressure, the disc swings open; when the flow stops or reverses, the disc swings closed by gravity and backflow pressure to form a seal. Main Specification of the Product Size Range 2" – 48" (DN50 – DN1200) Pressure Range 150 LB – 2500 LB Connection Ends FLG, BW Main Material WCB, WCC, LCB, LCC, GG25, GGG40, CF8, CF8M, 2205, Duplex Stainless Steel, etc. Bonnet Type Pressure Self-sealing, Bolted Bonnet Design & Manufacture ASME B16.34 / BS1868 Face-to-Face ASME B16.10 Connection Standards ASME B16.5 / ASME B16.47 A / ASME B16.25 Testing & Inspection API 598 Application Scope Petroleum, Chemical, Electric Power, Metallurgy, Medicine & other industries

The triple eccentric flange butterfly valve has three eccentricities. The first eccentric shaft deviates from the center line of the sealing surface, the second eccentric shaft deviates from the center line of the pipeline and the valve, and the third is the angle between the unique eccentric valve seat and the center of the pipeline. In this way, the valve seat and the sealing ring are completely separated during the entire switching process. Main Features Key Features Anti-blow-out stem design – safe & reliable. Stem position indicator + top mounting flange for easy position feedback. Torque-sealed construction guarantees sustained bi-directional zero-leakage performance. Connection Ends Flanged (FLG) Operation Lever, Gear, Electric, Pneumatic, etc. Main Materials WCB, 304, 316, CF8, CF8M, 2205, Alloy 20, … Sealing Materials Soft seat (EPDM, NBR, PTFE, …) or Metal-to-Metal Applications Solvents, acids, water, natural gas and other severe / demanding services Design & Manufacture API 609 Face-to-Face API 609 / ASME B16.10

200WOG Thread Globe Valve is a type of valve designed to regulate or isolate the flow of liquids or gases in a piping system. The term "200WOG" refers to its pressure rating and the type of fluid it can handle, while "Thread" refers to the type of end connections for the valve. This number refers to the pressure rating of the valve in terms of WOG, which stands for Water, Oil, and Gas. This means that the valve is rated for a maximum working pressure of 200 PSI (pounds per square inch) when handling water, oil, or gas. Indicates the type of media (water, oil, and gas) that the valve can safely handle. This rating indicates the valve's pressure tolerance for these fluids.

Forged Steel Gate Valve is a robust and high-performance type of Gate Valve primarily used for reliable on/off isolation in demanding service lines. The key distinction lies in its construction method: critical components like the body and bonnet are made from forged steel, a process that enhances the material's grain structure, resulting in superior mechanical strength, impact resistance, and integrity compared to cast equivalents. This makes it the preferred choice for high-pressure, high-temperature, or critical applications involving volatile fluids. As a certified manufacturer with integrated production and stringent quality control, Chenyu Valves supplies high-quality Forged Steel Gate Valves across these three bonnet designs, manufactured to international standards (such as ASME) for reliable performance in petroleum, chemical, power, and other critical industries.
