Product Description

An Electric Butterfly Valve is a specialized industrial assembly used to start, stop, or regulate the flow of a fluid through a pipeline.It consists of two primary components working together: a mechanical butterfly valve and an electric motor actuator.

Here is a breakdown of how they work, their key components, and how they are typically specified.

How It Works

A butterfly valve is a quarter-turn valve, meaning it only requires a 90-degree rotation to go from fully closed to fully open.

The Signal: A control system (like a PLC) sends an electrical signal to the actuator.
The Motor: The electric motor inside the actuator spins at a high speed.
The Gearbox: Because the motor spins fast but with low torque, a mechanical gearbox (usually a worm gear system) reduces the speed and massively increases the torque.
The Disc: The gearbox turns the valve stem, which rotates the internal disc 90 degrees inside the pipe to either block or allow fluid flow.

Key Components

1. The Electric Actuator (The Motor)

The actuator houses the electrical components that drive the valve.

Motor Type: Usually a reversible AC or DC motor.
Duty Cycle: Crucial for performance. A 20% duty cycle is fine for simple open/close operations, but modulating valves (which constantly adjust flow) require a 100% continuous duty cycle motor to prevent overheating.
Control Options: * On/Off (Isolating):Fully opens or fully closes the valve.
- Modulating (Regulating): Accepts a 420mA or 010V signal to position the disc at precise angles (e.g., 30% open) to control flow rate.
Fail-Safe Options: Some actuators include a battery backup or a mechanical spring-return to automatically close (or open) the valve if factory power is lost.

2. The Butterfly Valve Body

The mechanical part touching the process fluid.

Body Styles:
- Wafer: Sandwiched between two pipe flanges. Lightweight and economical.
- Lug:Has threaded lugs matching the pipe flanges. Allows for dead-end service (removing piping on one side while keeping the valve pressurized).
- Flanged: Features its own flanges; typical for very large diameters.
Seating Types:
- Resilient-Seated (Soft-Seated): Uses elastomers like EPDM, NBR (Buna-N), or VITON. Offers bubble-tight shutoff but is limited by temperature.
- High-Performance / Double-Offset: Uses a PTFE seat for higher pressures and temperatures.
- Triple-Offset (Metal-Seated): Uses a metal-to-metal seal for extreme temperatures, high pressures, and abrasive media.

Technical Specifications to Consider

When sourcing or pairing an electric motor actuator with a butterfly valve, the engineering specs must match perfectly:

Parameter	Description / Options	Why it Matters
Torque Rating	Measured in Nm or in-lbs	The actuator torque output must exceed the valve's breakaway torque (including a safety factor, typically 2030%).
Voltage	24V DC, 110V AC, 230V AC, 3-Phase 415V	Must match the available local or control-panel power supply.
Enclosure Rating	IP65, IP67, IP68, NEMA 4/4X, ATEX/Ex	Determines resistance to dust, water washdowns, or explosive atmospheres.
ISO 5211 Mount	F05, F07, F10, etc.	The international standard flange geometry for mounting the actuator directly to the valve top-plate.

Reliable Fluid Control for Industrial Demands

Engineered for precision and durability, this electric butterfly valve offers consistent performance across a range of process industries. Its robust body, corrosion-resistant coatings, and high torque actuator make it suitable for water, air, oil, and mild chemical applications. The actuator's IP67 weatherproof rating and wide operating temperature range enable performance in harsh settings, while its wafer type design offers convenient installation between flanges.

Efficient and Easy-to-Operate Actuation

The actuator delivers quick open/close cycles (15-30 seconds) with the flexibility of on/off and modulating control. Manual override with a handwheel, integrated limit switches, and a prominent visual position indicator ensure safe and straightforward usage by your maintenance team. Compatible with ISO 5211 mounting standards, it simplifies integration into existing pipelines.

FAQ's of Electric ButterFly valve:

Q: How does the electric butterfly valve operate and what control options are available?

A: The valve is motorized and uses an electric actuator to control the disc position, enabling both on/off and modulating flow regulation. Operation is controlled electrically (standard 220V AC, other voltages on request), with an integrated visual position indicator and limit switches for reliable feedback. Manual override by handwheel is included for emergencies or maintenance.

Q: What types of applications are suitable for this valve?

A: It is ideal for fluid management in water treatment plants, HVAC systems, chemical processing, and other industrial processes where precise flow control of water, air, oil, or mild chemicals is required. Its robust design supports reliable operation even under demanding and frequent cycling conditions.

Q: Where can this valve be installed and what are its connection requirements?

A: The valve is designed for wafer-type installation, fitting between standard pipeline flanges (DN50-DN300). Mounted via an ISO 5211 compatible flange, it integrates seamlessly into both new and retrofit piping systems across industrial, commercial, and municipal facilities.

Q: What process and maintenance features enhance the valve's reliability?

A: Features such as the powder-coated aluminum actuator, fusion bonded epoxy body, and stainless steel plate and stem deliver high corrosion resistance. Maintenance requirements are minimal, due to the actuator's weatherproof IP67 rating and the robust, self-lubricating design, supporting frequent operation without the need for extensive servicing.

Q: What benefits does the external visual position indicator offer?

A: The external visual position indicator provides immediate confirmation of valve status, enabling operators to assess open or closed positions at a glance, which improves workflow safety and efficiency during monitoring or manual operation.

Q: When should the manual override be used and how is it implemented?

A: Manual override with the standard handwheel should be used during power failures, actuator maintenance, or emergency shutoff scenarios. This feature ensures operational continuity and safe intervention without reliance on electrical control systems.

Q: What are the available configurations and material options for this valve?

A: The valve body is manufactured from cast iron or ductile iron, with a choice of epoxy coated iron or stainless steel butterfly plates. Sealing options include EPDM and PTFE, while stem material is stainless steel (AISI 410/304), supporting media temperatures from -20C to 120C and pressures of PN10/PN16.
