Self-Research Slide Gate Valve
Darko supplies the full range of slide gate valves for handling powder and granular materials. They are the perfect solution for isolating or intercepting material flow out of hoppers, silos and bins. Suitable for all industrial sectors and the food industry.
What is Slide Gate Valve?
Slide gate valves are linear motion valves in which a flat plate slides into the flow stream to provide a shut-off of material or air. The gate can close or open the slide plate on a moving column of material at all times. The slide plate of the gate is not, in most applications, open or exposed to people.
Slide Gate Valve By Features
The electric device is equipped with a torque control mechanism and supports manual emergency switching.
The handwheel is combined with a trapezoidal threaded valve stem, resulting in an opening and closing torque as low as 50N·m.
Supporting 4-20mA signal control, and can be linked with the DCS system to achieve remote opening and closing.
The Hydraulic-electric system has good stability and is highly reliable and stable for the long term using.

Whether you are an equipment integrator, automation engineering company, or OEM equipment manufacturer, you can get the most suitable customized solution according to your own needs, ensuring system compatibility, stability and ease of use.
Darko’s slide gate valve supports full-dimensional customization ranging from structural parameters to intelligent systems. And we also accept flexible quantity customization.
Our slide gate valves can be made of materials such as stainless steel, carbon steel or Hastelloy alloy. The sealing surfaces can be lined with PTFE or have a metal hard-sealing structure.
The slide gate valve offers the option of manual, electric, pneumatic or hydraulic drive. At the same time, it can be integrated with remote control and automation interfaces.
Darko’s slide gate valves are capable of undergoing a 72-hour continuous pressure cycling test (API 598-2024 standards), as well as the required extreme environment simulation tests.
For different industrial application scenarios, Darko can customize slide gate valves with different levels of protection to ensure that the valves can still operate stably in extreme environments.
We can customize the appearance color, brand Logo, label information according to customer’s needs, and support customer’s exclusive device logo at the software level to improve brand recognition.
Bidirectional Capability
The slide gate valves are typically designed for bidirectional flow, ensuring that fluids can pass through smoothly in both directions. This design effectively prevents fluid stagnation within the valve body and adapt to the potential flow direction adjustment needs in pipelines..
Easy to Open and Close
The fluid dynamics design of the slide gate valve body optimizes the fluid flow and reduces the resistance during opening and closing, thereby making the operation more effortless. We choose high-strength and lightweight materials can reduce the overall weight of the valve, thereby minimize the burden during opening and closing.
Low-Carbon Steel
We use low-carbon steel to reduce carbon emissions during the production process, which is in line with the requirements of sustainable development. The use of low-carbon materials can enhance the working efficiency of valves, reduce the energy loss during fluid flow, and thereby decrease the overall energy consumption.
Dust dispersion < 0.5mg/m³
The slide gate valve adopts a dual combination of metal hard seal (with tungsten carbide coating) and fluorine rubber soft seal. It is driven by pneumatic or electric means, which reduces the dust disturbance caused by manual operation and lowers the risk of leakage.
Slide Gate Valve Application cases
As a key cutoff component in fluid control systems, slide gate valves demonstrate irreplaceable characteristics in high-temperature and high-pressure conditions due to their full-bore and low-flow-resistance design. Modern slide gate valves are evolving towards smart technology, with some high-end models integrating pressure sensors and IoT modules to enable predictive maintenance functions
Rotary airlock Valve VS Slide Gate Valve
1. Rotary Airlock Valve
The Rotary Airlock Valve is for continuous quantitative discharge. It utilizes a rotating impeller for material transport while also providing pneumatic isolation to prevent pressure imbalances in the pneumatic conveying system.
2. Slide Gate Valve
The Core Function is Flow Cutoff. The primary function is to interrupt the flow of the medium, achieved through the vertical movement of the gate plate for full open/close control of the pipeline. This is suitable for high-viscosity conditions or those containing solid particles.
1. Dual Sealing Protection
The slide gate valve is responsible for pipeline-level cutoff (completely isolating the medium during maintenance), while the rotary airlock valve achieves dynamic air lock through a rotating impeller. Together, they effectively prevent backflow of air and material leakage.
2. Process Control Optimization
The slide gate valve is used for coarse flow adjustment (fully open/fully closed), while the rotary airlock valve utilizes a speed control motor for precise quantitative feeding (such as controlling the amount of cement raw material added).

Customer Feedback
-
We use the Darko’s brand valves in a high-temperature dust environment, and there has been no leakage within three years.
Adrian ApeririCEO, Wholesale Brand -
We paired Darko’s slide gate valve with an electromagnetic valve and a proximity switch, and now the valve responds in under a second. Plus, the remote control accuracy is within ±1mm, which perfectly meets our cement production line’s need for precise throttling.
Adrian HarmonCEO, Wholesale Brand -
The special manufacturing process of Darko’s slide gate valves, which features self-cleaning flow channels, has reduced the failure rate of stuck valves by 80%.
The production cycle for standard slide gate valves is usually between 1 and 2 weeks, while custom slide gate valves may take more than one month.
Generally speaking, the price of customized slide gate valve is usually higher than that of standard slide gate valve. Although customized slide gate valves are more expensive, their functions and adaptability often can meet specific needs, so in some cases, investing in custom products is worthwhile.
Yes, usually, by purchasing in bulk, you can enjoy better price discounts.
