The new Pinch Valve from LAD uses various materials such as cast iron, carbon steel, stainless steel, and aluminum alloy. It comes in two structures: closed and bare. Additional components, such as a positioner, solenoid valve, limit switch, air filter, and junction box, can be retrofitted for remote control. The valve body has a flat and aesthetically pleasing appearance and can be painted. It is an ideal substitute for imported valves. The sleeve is handmade using solid-liquid, two-phase rubber as the main material, reinforced with cord fabric, and finally synthesized with natural rubber. It is lined for added durability.

LAD's air-operated pinch valve incorporates materials such as cast iron, cast aluminum, carbon steel, or stainless steel in its valve body composition. Its operating principle relies on the gap between the valve body and the sleeve to deform the sleeve, thereby interrupting the flow and controlling the medium, which can be either air or water, at a pressure range of 3-6 bar. The manufacturing process of the lining sleeve is purely manual, using mainly two-phase LNT rubber reinforced with canvas and finally synthesized with natural rubber.

LAD's Company's combination through-penetration slurry knife gate valve is made of materials such as cast iron. It allows for optional attachments such as solenoid valves, limit switches, and air source filters. The areas traversed by the fluid flow are fully rubber-lined, allowing quick and convenient replacement of vulnerable parts for ease of assembly and cost-effectiveness. Two critical aspects highlight the valve's robust sealing characteristics: The seat uses movable sealing technology. The "O" ring's preload force holds the seat firmly against the valve plate, significantly minimizing potential leakage. In addition, an automatic compensation feature is incorporated to counteract the long-term wear of sealing components. This feature extends the life of the material and eliminates problems such as air leaks, water seepage, dripping, or leakage during transport. Rubber lining materials include options such as natural rubber (black rubber),LNT (a special red rubber from LAD Company), EPDM, and butyl rubber. These materials are formulated for different operating conditions. Blade plate material options include 304, 316/2205, and others.

LAD's Company's Zero Gap Gate Valve is made of materials such as cast iron, riveted carbon steel, or stainless steel, with a double clamp structure. It can be equipped with optional accessories such as solenoid valves, limit switches, and air source filters. The sealing rings are available in materials such as natural rubber (black rubber), LNT (a special red rubber manufactured by LAD Company), EPDM, and NBR, formulated with specific compositions tailored for various operating conditions. Generally, internal reinforcing ribs are included to increase its resistance to deformation. Blade plate material options include 304, 316/2205, and others.

LAD's Company's rubber-lined gate valve is a common type of gate valve made of riveted carbon steel with wedge-shaped sealing sides. This design allows for the opening or closing of media flow in pipelines. However, wedge gate valves are not suitable for partial opening due to the high-velocity flow of the medium, which can cause erosion and accelerate damage to the sealing surface. Therefore, they cannot be used as throttling devices in pipeline applications. The rubber-lined gate valve is easy to operate and supports various actuation modes, including manual, worm, and electric. The valve body's internal rubber lining uses a special rubber from LAD Company, which provides high abrasion resistance and corrosion protection. The rubber lining layer is repairable, ensuring low maintenance costs.

The LAD's Company's rubber-lined check valve is designed for installation in horizontal pipelines. The valve body has a swing-type carbon-steel riveted structure. When the valve is opened, the pressure of the medium in the designed flow direction pushes the valve disc open, allowing the valve to function normally. When the valve is closed, the backflow pressure forces the disc tightly against the sealing surface of the valve body, preventing slurry backflow. Proper orientation is crucial when installing the valve since it cannot be installed upside down. The c sleeven model must meet the pipeline's working pressure requirements. The valve body's internal rubber lining uses a special rubber from LAD Company, which provides high abrasion resistance and corrosion protection. The rubber lining layer is repairable, contributing to lower maintenance costs.

The LAD's Company's three-way rubber-lined directional check valve, also known as a Taylor valve, is made of a riveted carbon steel valve body with upper and lower sections and a rubber-lined ball element. This valve uses the fluid medium to automatically propel the rubber-lined ball, thereby changing the inlet path of the medium. Once installed, it operates autonomously without manual intervention, seamlessly managing the opening and closing actions. This valve has the potential to replace two or four conventional valves, offering exceptional safety, reliability, and superior sealing capabilities. The valve body and ball component have internal surfaces coated with LAD Company's special rubber, which is known for its exceptional resistance to wear and corrosion. The rubber lining layer is repairable, ensuring cost-effective maintenance solutions.

LAD's Company's vertical rubber-lined check valve is designed for installation in horizontal pipelines. The valve body has a swing-type carbon steel riveted structure. The valve disc relies on the pressure of the medium in the designated flow direction to facilitate normal operation during opening. When closing, the reverse flow pressure tightens the valve disc against the valve body's sealing surface, preventing slurry backflow. Proper directional installation is crucial since it cannot be installed in reverse. The selected model must meet the pipeline's working pressure requirements. The valve body's internal rubber lining uses specialized rubber from LAD Company, known for its high wear resistance, corrosion protection, repairable lining layer, and low maintenance costs.

LAD's Company provides two types of pipeline expansion joints: rubber sleeve expansion joints and rubber-lined expansion joints. Both types consist of an inner sleeve, an outer sleeve, and a rubber-sealed sleeve. The inner and outer sleeves utilize a steel-lined rubber structure, making them ideal for slurry and gas pipelines. These joints effectively reduce vibrations and noise within the pipeline system. In addition, they effectively address issues related to thermal expansion and contraction, axial expansion differences, and varying concentricities in pipelines. The design with a flexible connection simplifies installation and maintenance. The rubber sleeve and inner lining rubber components of the entire assembly use LAD Company's specialized rubber, providing high wear resistance and corrosion protection.

The rubber expansion joint from LAD's consists of a flange and a cylindrical structure with two rubber layers: an inner layer that provides a sealing function and an outer layer that protects and supports. LAD uses specialized rubber that is highly resistant to abrasion and corrosion for these joints. Reinforcing ribs are commonly present internally to improve deformation resistance. This flexible joint is widely used in various piping systems due to its excellent flexibility and sealing properties. Its advantages are particularly prominent in high-pressure, low-temperature, and corrosive environments.
