Specifications of China Nitrogen LPG Cryogenic Short Stem Flange Type Globe Valve Stop Control Valve Low Temperature Pipe DJ61F DJ41F Gas Valve

Below’s the product summary for China Nitrogen LPG Cryogenic Short Stem Flange Kind Globe Valve Stop Control Valve Low Temperature Pipeline DJ61F DJ41F Gas Valve. We designed these valves for tough cryogenic tasks. They manage extremely chilly liquids like liquid nitrogen and LPG securely. These fluids reach temperature levels as low as -196 ° C. You need reputable shutoffs for this.

The valve body makes use of strong stainless-steel. This material stays tough in severe cold. It prevents brittleness and splitting. The special layout consists of a short stem. This short stem is key. It minimizes warmth entering into the valve body from outside. Warmth entering causes troubles. It can make the liquid boil or ice up the shutoff components. The short stem quits this.

We offer 2 primary kinds: DJ61F and DJ41F. Both feature a flanged connection. Flanges make installation simple. They likewise make sure a tight, leak-free seal under stress. These are world shutoffs. Globe valves give you accurate circulation control. You can open them a little or a lot. This makes them outstanding stop control valves for process lines.

These valves function well in low temperature piping systems. Typical uses consist of LNG plants, commercial gas facilities, and chemical handling. They manage circulation successfully. They additionally turned off totally when needed. Safety is critical with cryogenic liquids. These shutoffs deliver that safety.

Integrated bonnet seals handle the thermal tightening. Materials increase and get with huge temperature adjustments. The seals remain tight. This prevents dangerous leaks. The shutoffs satisfy worldwide standards like ISO and ANSI. This guarantees compatibility and performance worldwide. Select them for dependable procedure in your chilliest applications.

Applications of China Nitrogen LPG Cryogenic Short Stem Flange Type Globe Valve Stop Control Valve Low Temperature Pipe DJ61F DJ41F Gas Valve

China’s nitrogen and LPG cryogenic brief stem flange kind world shutoffs, like versions DJ61F and DJ41F, control circulation efficiently in really cold systems. They stop or regulate fluids and gases. These shutoffs take care of severe reduced temperature levels dependably. They function well with fluid nitrogen, liquid oxygen, argon, LNG, and LPG. Their design stops leaks and guarantees safety in critical processes.

These shutoffs utilize a short stem layout. This is important for cryogenic service. It decreases warmth transfer right into the shutoff body. Much less warm transfer stops ice forming on the stem. Ice development can trigger sticking or damages. The prolonged hood design maintains the stem packing warmer. Warmer packing remains versatile and seals better at reduced temperatures. Flange connections bolt directly to pipes. This supplies a strong, leak-proof seal under pressure. Globe valves provide accurate circulation control. They are good for strangling applications and limited shut-off.

Suppliers build these valves from special products. Usual products include stainless steel or carbon steel treated for low temperatures. These products resist coming to be weak in the cold. Fragile materials can split and fail. The shutoffs feature durable securing surfaces. This guarantees tight closure also after numerous cycles. They take care of high-pressure differences reliably.

Industries depend on these valves extensively. Petrochemical plants use them for processing and keeping dissolved gases. LNG terminals manage liquefied natural gas transfer and storage space with them. Commercial gas manufacturing requires them for dividing, saving, and carrying gases like nitrogen and oxygen. Chemical handling uses them for handling various cryogenic fluids. They are crucial in cold storage facilities also. These valves perform requiring jobs in challenging atmospheres. They are crucial components for secure, reliable cryogenic procedures.

5 FAQs of China Nitrogen LPG Cryogenic Short Stem Flange Type Globe Valve Stop Control Valve Low Temperature Pipe DJ61F DJ41F Gas Valve

Here are five common questions about China Nitrogen LPG Cryogenic Short Stem Flange Type Globe Valves (DJ61F, DJ41F):

What is this valve used for? This valve controls or stops the flow of very cold liquids and gases. It’s built for systems handling liquefied petroleum gas (LPG), liquid nitrogen, oxygen, argon, and similar substances at extremely low temperatures. These valves handle critical shut-off jobs in pipelines, storage tanks, and processing plants dealing with super-cold materials.

Why is it called “cryogenic”? Cryogenic means extremely cold. Normal valves fail or leak at these temperatures. This valve uses special materials and designs. It features an extended bonnet and a short stem. This design keeps the stem packing seals warmer. The seals stay flexible. They don’t freeze up. They prevent leaks reliably down to temperatures like -196°C (-320°F).

What materials make it suitable for cold service? The body and bonnet are usually tough stainless steel. This steel stays strong and doesn’t become brittle in the deep cold. Critical sealing parts use specialized materials like PCTFE or reinforced PTFE. These materials keep their sealing ability and flexibility even at cryogenic levels. They resist cracking.

What pressure can it handle? These valves are strong. They typically handle pressures from Class 150 to Class 600. This means pressures up to roughly 100 bar or 1450 psi, depending on the specific class rating. The exact pressure rating depends on the valve size and class. Always check the specifications for your model and application.

How should it be installed? Correct installation is vital for cryogenic valves. Install the valve with the stem upright. The valve must be vertical. Installing it upside down or sideways risks trapping liquid in the bonnet. Trapped liquid can expand violently as gas. This creates dangerous pressure. Mounting it upright lets any trapped liquid safely drain back into the pipeline.
