Typically, applications requiring high flow rates and quick response times use motorized gate valves or electric actuated gate valve. These valves can be opened using either a hydraulic or an electric actuator. Electric actuators are frequently more economical than their hydraulic counterparts and are typically used for applications requiring quick response times.
Plant damage can be reduced by using electric actuators to regulate the opening and closing of valves like the resilient gate valve. They are non-toxic, quiet, and energy-efficient. They are also responsive to remote control and work with centralized process control systems. Through the reduction of injuries, these devices also improve plant safety.
Identifying the torque necessary to operate the valve is the first step in selecting an electric actuator for the valve. The required torque is typically 1.2 to 1.5 times the maximum torque of the valve. Higher torques are necessary for some applications, though. In these cases, the oversized actuator can be managed by a relief valve or regulator.
The signal that controls the torque in a valve electric actuator is divided into voltage and current signals. The controls will either shut off the motor or distinguish between a normal operation and a tripped switch if the control torque is exceeded.
Electric multi-turn gate valves typically have one or three phase electric motors installed. Electric actuators with multiple turns are a dependable and portable option for controlling valves in hazardous environments. The actuators' modular construction offers a variety of options and functionalities.
Electric multi-turn actuators are also made to provide precise valve control in risky environments. In addition, they have explosion-proof certification. They frequently have a hand wheel installed for manual control. For fail-safe operation, batteries can also be added to them. The motor power is also cut off by a torque-sensing device when the safety torque is exceeded.
Rising valve stems are a common feature of multi-turn gate valves or motorized gate valve. By means of a threaded rod, the rising stem moves the obstruction. The valve is then opened or closed as a result of the valve stem nut's engagement with the valve stem.
Electro-hydraulic fail-safe motorized gate valves don't need additional maintenance, unlike hydraulic actuators. Additionally, they offer greater availability and safety.
The oil and gas industry employs these valves. They can be put in pipelines, tank farms, and production wellheads. Pneumatic or hydraulic systems can operate them.
Extreme operating conditions require the use of these systems. They are constructed entirely of steel and are intended for heavy-duty industrial applications. There are numerous designs for these systems. They consist of linear type valves and valves with non-lifting stems like the two way gate valve.
The mainframe structure of these systems is connected to the thread head. The stem thread pitch and valve opening height are also influenced by the mainframe structure. The output torque is transformed into valve thrust by this structure.
Resilient-seated motorized gate valves are used in applications where little maintenance is required because they are built to last for years. Applications for these valves include irrigation, drinking water supply, and the treatment of water and wastewater. They are made to be simple to use and maintain.
The body, gate, bonnet, stem, and valve seat are the main parts of a motorised gate valve with resilient seating. Stainless steel with a high corrosion resistance makes up the body. The body and bonnet are bolted together. A robust material, such as ductile iron, is used to mold the gate.
Fibrous slurries, corrosive liquids, and dirty liquids are all handled by these valves. They work well for pumping filthy water as well.
Stainless steel with a high corrosion resistance makes up the valve body. During valve installation, support is provided by its face-to-face dimension. The flanges adhere to the 150-lb. ANSI B16.5 standard. The valve's face-to-face dimension should be at least 20mm larger than the flanges. It's critical to adhere to good engineering practices when installing flanges.
The hydro-static testing of the valves like auto air release valve has been guaranteed by the AFC Valve factory. Typically, 1.1 * pressure rating for the seat test and 1.5 * pressure rating for the shell test are used in pressure tests. We can be sure that every valve in the water system will be properly maintained thanks to the test valve. We followed the standard EN12266. All goods that satisfy UL or FM requirements are UL/FM certified. process.
The standard manufacturing process like for combination air valve strictly regulates each manufacturing step. Every step, including castings as well as machining, coating, and casting, has been recorded by AFC's quality systems. Inadequate process control is the cause of low quality product.
The valve's design such as in automatic air release valve is the result of extensive user feedback and thirty years of industry experience. Our product is more effective and safe at work. Each valve's design adheres to a different set of standards. One illustration is gate valves. Standards such as EN, AS, UL, UL, or FMS can be met. Butterfly valves with double embroids adhere to AWWA and EN standards. Each item must adhere to the requirements set forth by the manufacturer of that item.
The largest and most efficient supply chain is in China. The valve's largest cost such as for air release valve is its castings. China is a top-notch casting supplier, and the prices are still fair. It is possible to evaluate both price and quality. The best way to strike a balance between cost and quality is with an AFC valve.
Gate valves are typically forged from ductile iron or cast carbon steel. Their typically wedge-shaped parallel gate faces have parallel edges. Typically, this kind of valve is utilized in heating circuits and larger pipe diameters. In some cases, they are additionally equipped with bypass valves to lower pressure prior to operation.
A power source that has the ability to open and close a gate valve manually is known as a motorized gate valve. Additionally, it is built to withstand voltage shocks. All applications requiring a multi-turn valve can use this kind of valve.
The fact that the gate motion is contained within the valve itself is the best feature of this type of valve. A threaded stem may also be used to open the gate. The ability to precisely align the motion is an additional benefit.
