Class 150 blind flange

Advantages: Necked flat welding flanges are also classified as flat welding flanges, as they have a short neck, which improves the strength of the flange and improves its load-bearing capacity. So it can be used on higher pressure official roads. Disadvantages: Compared to plate type flat welding flanges, they have a higher cost and are more prone to collision during transportation due to their shape characteristics.

Blind flange, also known as blind flange, is officially called flange cover. It is a flange without a hole in the middle, used to seal pipeline plugs. There are many types of sealing surfaces, including flat, convex, concave convex, tenon groove, and ring connection surfaces.

Overview of Z43WF manual flat gate valve: Z43WF manual slab gate valve is suitable for natural gas, petroleum, chemical, environmental protection, urban pipelines, gas pipelines and other transportation pipelines, venting systems and steam storage devices, as opening and closing equipment. Suitable for long-distance pipelines for natural gas extraction and purification.

Forged steel ball valves work by rotating the stem to keep the valve open or blocked.

The solenoid valve has a sealed chamber with through holes at different positions, each connected to a different oil pipe. The middle of the chamber is a piston, and there are two electromagnets on both sides. The magnetic coil on which side is energized will attract the valve body to which side. By controlling the movement of the valve body, different oil discharge holes can be opened or closed. The oil inlet hole is usually open, and hydraulic oil will enter different oil discharge pipes, and then push the piston of the oil cylinder through the pressure of the oil, The piston drives the piston rod, which drives the mechanical device. In this way, mechanical motion is controlled by controlling the current flow of the electromagnet.

The "8" character is a type of pipeline component, mainly for the convenience of maintenance. You can paint the upper half of the "8" character black to determine the specific shape. It's half a blind plate and half an iron ring. Commonly used for pipeline flanges that require process changes, the materials mainly include carbon steel, stainless steel, and alloy, which can be selected based on the pipeline pressure level and pipeline medium.

The check valve is automatically opened and closed by the force of the flow of the medium itself in the pipeline, which belongs to an automatic valve.

A butterfly valve plays an important role in the food sanitation industry. This product is made of 304 stainless steel, which is safe, durable, and rustproof. You can use it for a long time and save your use cost. In addition, this product can well control the flow of materials. It is simple to install, easy to use and saves your time. You can buy it with confidence.

The PZ273H electro-hydraulic knife type gate valve controls the opening and closing of the valve through the reciprocating push position of the electro-hydraulic linkage device. If equipped with sensors or digital display devices, it can be centrally or programmatically controlled in remote and high-altitude hazardous areas. It is widely used in industries such as metallurgy, power, coal, mining, and water conservancy, and is a new and updated replacement product with strong applicability.
