Product Specifications and Overview

ALIS Valves offers Electric Lug Type Butterfly Valves for industrial applications requiring reliable flow regulation, shut-off and automated operation. These valves feature a rotating disc that controls fluid flow through a quarter-turn mechanism, allowing the valve to open, close or regulate flow according to system requirements. The lug-style body incorporates threaded lugs around the valve perimeter, enabling installation between compatible pipeline flanges and, in suitable configurations, allowing one side of the pipeline to be disconnected while the other remains secured. An electric actuator provides remote operation and can support integration with compatible industrial automation systems.

Electric Lug Type Butterfly Valves are suitable for applications in water treatment plants, chemical processing facilities, HVAC systems, power generation units and industrial fluid distribution networks. They can be used with compatible liquids and gases within the specified pressure and temperature limits. Important selection factors include process media, operating pressure, temperature, flow rate, valve size, body and disc materials, seat compatibility, flange drilling, actuator voltage and control requirements. Selecting the appropriate valve configuration helps support dependable shut-off, efficient flow regulation and reliable automated operation under the intended working conditions.

Frequently Ask Questions

What Is an Electric Lug Type Butterfly Valve?

It is a lug-style butterfly valve operated by an electric actuator for automated flow isolation and control in industrial piping systems.

Can a Lug Type Butterfly Valve Be Used for Dead-End Service?

Yes, properly rated lug-style butterfly valves can be used for dead-end service, subject to the manufacturer's pressure and installation requirements.

Who Is an Electric Lug Type Butterfly Valve Manufacturer in India?

Alis Valves manufactures and supplies Electric Lug Type Butterfly Valves for water treatment, oil & gas, chemical processing, HVAC, power, petrochemical, and other industrial applications.

How should the fail-open or fail-closed position be selected?

The required fail position depends on the process safety requirements. Standard electric actuators may not automatically move the valve to a safe position after power loss. If fail-open or fail-closed operation is required, specify an actuator with a suitable spring-return, stored-energy or other approved fail-safe mechanism.

What Is the Advantage of a Lug Type Butterfly Valve?

The lug body has threaded mounting holes around the valve, allowing it to be securely bolted to the pipeline and providing greater installation flexibility than a wafer-style design.

What Is the Difference Between Lug and Wafer Butterfly Valves?

A lug valve has threaded mounting holes and can be individually bolted to the pipeline, while a wafer valve is generally clamped between pipeline flanges using through-bolts.

How is the required actuator torque calculated for an electric lug type butterfly valve?

Actuator torque selection should be based on the valve manufacturer's torque data at the specified differential pressure, operating temperature and service conditions. The selection should also account for the manufacturer's recommended safety margin and the actuator's available output torque throughout its operating range.

How should the actuator's open and closed travel limits be set?

Set travel limits according to the valve manufacturer's instructions and actuator design. Confirm that the disc reaches the intended positions without applying excessive force to the seat or mechanical stops, and verify position feedback during commissioning.
