Valves with Electric Actuators for Industrial Automation

We offer valves with electric actuators for automatic and precise fluid control in industrial processes. Additionally, we have ball and butterfly valve assemblies in stainless steel, PVC, and anti-corrosive materials. Therefore, you will always find the right configuration for your process. Furthermore, all our products are delivered assembled, calibrated, and tested, ready for installation.

What advantages does an electric actuator offer over a pneumatic one?

Before choosing, it's important to understand when an electric actuator is most suitable. For example, it is the best option when there is no compressed air network available, or when the process requires precise modulating control. Below, we explain its main advantages:

• No compressed air required: Operates solely on electrical power. Therefore, it is ideal for installations where no pneumatic network is available or where its installation would be costly. Furthermore, it eliminates the operating costs of the compressor and losses due to air leaks.
• Integrated modulating control: Modulating models position the valve at any point between open and closed using a 4-20 mA or 0-10V signal. This allows for precise flow regulation without the need for an external positioner. Therefore, they simplify installation and reduce costs.
• Integration with control systems: They are compatible with PLCs, SCADA, and distributed control systems. Modulating models also offer electrical position feedback to confirm the valve's status in real-time. Therefore, they are the preferred choice in plants with a high level of automation.
• Available in Ex-Proof version: Explosion-proof models have international certifications for hazardous areas. Additionally, they are also available with spring-return fail-safe closure for added safety. Therefore, they cover the most demanding applications in petrochemicals and gas.

Electric ball valve assemblies: NPT thread and clamp

Below, we present the ball valve models with threaded and clamp connections. Furthermore, all feature an ISO 5211 mounting pad for direct coupling without adapters. Therefore, installation is quick and hassle-free:

• SS 316 NPT Thread Ball Valve with Electric Actuator: This is the most versatile model for general industrial installations. In addition, its 316 stainless steel body ensures corrosion resistance. Therefore, it is the most common option in manufacturing, water, and processes with neutral or mildly aggressive fluids.
• 3-Way NPT Thread Ball Valve with Electric Actuator: Allows flow diversion between two outlets with a single actuator. Therefore, it simplifies installation by eliminating the need for two independent assemblies. It is also available in ON-OFF and modulating modes for greater control flexibility.
• Clamp Ball Valve with Electric Actuator: Its clamp connection makes it suitable for hygienic applications in the food and pharmaceutical industries. It also allows for quick disassembly for CIP and SIP cleaning. Therefore, it is the required option when the process must comply with sanitary standards.
• PVC Ball Valve with Electric Actuator: It is lightweight and highly resistant to chemical corrosion. Therefore, it is ideal for corrosive fluids, water, and low-pressure systems. In addition, its low cost makes it the most efficient option for water and effluent treatment applications.

Electric ball valve assemblies: flanged, Ex-Proof and fail-safe

In addition to the threaded models, we have flanged and safety versions for critical applications. Therefore, if your process operates at high pressure or in hazardous areas, you will find the appropriate configuration below:

• ANSI 150 Flanged Ball Valve with Electric Actuator: This is the recommended option for high-pressure systems with flanged connections. In addition, the 316 stainless steel body ensures durability in demanding environments. Therefore, it is widely used in petrochemical, energy, and industrial water applications.
• 3-Way ANSI 150 Flanged Ball Valve with Electric Actuator: Combines the robustness of the ANSI flange with the versatility of flow diversion. Therefore, it is ideal for high-pressure systems that require mixing or distribution between two circuits. In addition, its ISO 5211 mounting pad facilitates actuator replacement without disassembling the valve.
• Ball Valve with Fail-Safe and Ex-Proof Actuator: Incorporates automatic spring-return closure in the event of a power outage. This ensures that the valve returns to its safe position in case of electrical failure. In addition, its explosion-proof certification makes it suitable for areas with flammable atmospheres in petrochemicals and gas.

Electric butterfly valve assemblies: standard seats

In addition to the ball valve models, we offer a wide range of butterfly valves with electric actuators. Therefore, if your process operates with medium or large diameter pipes, you will find the appropriate option below based on the fluid and operating temperature:

• Wafer Butterfly Valve EPDM Seat with Electric Actuator: This is the most common option for water, low-pressure steam, and neutral fluids. Additionally, the EPDM seat resists temperatures up to 150°C. Therefore, it is widely used in potable water systems, HVAC, and general manufacturing.
• Wafer Butterfly Valve NBR Seat with Electric Actuator: Ideal for mineral oils, fuels, and petroleum-based fluids. Therefore, it is the recommended option in the automotive and manufacturing industries. However, it is not suitable for hot water or steam.
• Wafer Butterfly Valve Viton Seat with Electric Actuator: Offers the highest chemical resistance among available elastomers. Therefore, it is the preferred seat for acids, aromatic solvents, and hydrocarbons at elevated temperatures. Additionally, it resists temperatures up to 200°C.
• Wafer Viton Butterfly Valve Series 200 with Electric Actuator: This is a higher performance version of the standard Viton model. It is also designed for more demanding applications where extended seat life is required. Therefore, it is ideal for processes with frequent opening and closing cycles.
• PVC Anti-corrosive Butterfly Valve with Electric Actuator: It is lightweight and resistant to chemical corrosion. Therefore, it is ideal for corrosive fluids or water in low-pressure systems. Additionally, its low cost makes it the most efficient option for water and effluent treatment installations.

Electric butterfly valve assemblies: anti-corrosive and special versions

In addition to the standard models, we offer anti-corrosive, high-performance, and control versions for more demanding applications. Therefore, if your process handles aggressive fluids or requires precise flow regulation, you will find the appropriate option below:

• Wafer Butterfly Valve Teflon Seat with Electric Actuator: PTFE is chemically inert to almost all fluids. Therefore, it is the most versatile option for demanding chemical and anti-corrosive applications. It also complies with FDA food contact regulations.
• Carbon Steel Butterfly Valve with Teflon Disc and Seat with Electric Actuator: Both the disc and seat are made of PTFE, offering maximum anti-corrosive protection. Therefore, it is the required option for highly aggressive fluids in the chemical and petrochemical industries.
• 316 Stainless Steel Butterfly Valve with Electric Actuator: Combines the resistance of the SS 316 body with a PTFE seat. It is also compatible with a wide range of industrial and sanitary fluids. Therefore, it is one of the most versatile and durable options in our collection.
• High-Performance Butterfly Valve with Electric Actuator: Its double eccentric design eliminates friction during closure. This provides longer service life, better sealing, and reliable operation at high pressures. Therefore, it is the recommended option in petrochemicals, energy, and mining.
• Linear Electric Control Valve for Flow Regulation: Unlike 1/4 turn models, this assembly uses a linear actuator to regulate flow with maximum precision. Therefore, it is the solution for continuous control processes where precision is critical. It is also available in stainless steel and is compatible with a 4-20 mA signal for integration with advanced control systems.
