ERA Butterfly Valve for Reliable Flow Control in Piping Systems

The ERA Butterfly Valve provides a practical solution for isolating and regulating the flow of water and other compatible fluids in piping systems. Its compact valve body and quarter-turn operation make it suitable for applications where convenient control, efficient installation, and minimal space requirements are important.

Available from Pinoleakpes Corporation, the ERA Butterfly Valve may be considered for water distribution, commercial plumbing, irrigation, wastewater systems, industrial utility lines, water-treatment facilities, and other compatible piping applications.

Choosing the correct valve size, material, connection type, seat, pressure rating, and operating method helps support dependable flow control and long-term piping performance.

What Is an ERA Butterfly Valve?

An ERA Butterfly Valve is a quarter-turn valve that uses a rotating disc to control fluid movement through a pipeline.

The disc is mounted on a shaft inside the valve body. When the operator turns the handle or gearbox, the disc rotates between the open and closed positions.

When the disc is aligned with the pipeline, fluid can pass through the valve. When the disc is turned perpendicular to the pipeline, the flow is restricted or stopped.

Depending on the selected model, an ERA Butterfly Valve may be supplied with different:

• Body materials

• Disc materials

• Seat or liner materials

• Connection designs

• Operating mechanisms

• Pressure ratings

• Sizes

• Flange compatibility

• Chemical-resistance properties

The exact product specifications should be reviewed before installation.

Why Choose an ERA Butterfly Valve?

Compact Valve Design

The ERA Butterfly Valve generally requires less installation space than many traditional linear-motion valves.

Its compact construction makes it practical for mechanical rooms, utility lines, water systems, and piping layouts with limited available space.

Fast Quarter-Turn Operation

The valve can typically be opened or closed by rotating the operator approximately one-quarter turn.

This simple operating method allows convenient system isolation and flow adjustment.

Practical Flow Control

An ERA Butterfly Valve may be used for shutoff service and selected throttling applications within its approved operating limits.

The valve position can be adjusted to help control the amount of fluid passing through the pipeline.

Lightweight and Easy to Handle

Depending on its size and material, the ERA Butterfly Valve may be lighter than some metal valve alternatives.

A lighter valve can help simplify transportation, handling, positioning, and installation.

Suitable for Different Piping Systems

ERA Butterfly Valves may be considered for compatible thermoplastic, waterworks, utility, commercial, agricultural, and industrial piping systems.

Actual suitability depends on the fluid, temperature, pressure, flow conditions, valve materials, and project specifications.

How Does an ERA Butterfly Valve Work?

The ERA Butterfly Valve operates through a circular disc positioned inside the valve body.

The disc is connected to a shaft that is controlled by a lever handle, gear operator, actuator, or another compatible operating mechanism.

The basic operating positions are:

Fully Open

The disc is positioned parallel to the direction of flow, allowing fluid to pass through the valve with reduced obstruction.

Partially Open

The disc is positioned at an angle to regulate or limit the amount of fluid passing through the pipeline.

The valve should only be used for throttling when permitted by the manufacturer and system design.

Fully Closed

The disc is positioned across the flow path and presses against the seat to stop or significantly restrict fluid movement.

The valve must be operated within its approved pressure, temperature, and flow limitations.

Common Types of ERA Butterfly Valves

The available valve configuration may vary according to the product series and project requirements.

Lever-Operated Butterfly Valve

A lever-operated ERA Butterfly Valve allows manual opening, closing, and position adjustment.

This configuration is commonly considered for smaller sizes and applications requiring convenient manual operation.

Gear-Operated Butterfly Valve

A gear operator provides additional mechanical advantage when operating larger valves or valves exposed to higher operating torque.

The handwheel allows the operator to open and close the valve gradually.

Wafer-Type Butterfly Valve

A wafer-type valve is installed between two compatible pipe flanges.

Long bolts or studs pass through the connected flanges and hold the valve in position.

Lug-Type Butterfly Valve

A lug-type butterfly valve has threaded or reinforced mounting points around the valve body.

This configuration may support different piping arrangements depending on the product design and manufacturer’s limitations.

Actuated Butterfly Valve

An ERA Butterfly Valve may be paired with a compatible electric or pneumatic actuator for automated flow control.

The valve and actuator must be properly sized according to the operating torque and control requirements.

Key Benefits of ERA Butterfly Valve

Efficient Pipeline Isolation

The ERA Butterfly Valve provides a convenient way to isolate sections of a piping system during operation, inspection, maintenance, or repair.

Space-Saving Installation

Its short face-to-face dimension can help reduce the installation space required between connected piping components.

Simple Operating Mechanism

Quarter-turn operation makes the valve easy to understand and operate when installed correctly.

Serviceable Valve Arrangement

Depending on the selected design, the valve may be removed for inspection, repair, seat replacement, or system modification.

Versatile Application Options

Different sizes, materials, operators, and connection configurations may be available for various piping requirements.

Suitable for Manual or Automated Control

The valve may be operated manually or integrated with a compatible actuator, depending on the selected model.

The valve material must be compatible with the fluid and operating environment.

Installation Environment

Consider whether the valve will be installed indoors, outdoors, underground, in direct sunlight, in a corrosive environment, or in an area exposed to vibration.

Additional protection or support may be required.

Proper Installation of ERA Butterfly Valve

Correct installation is essential for reliable valve operation and sealing.

Before installation, inspect the valve for visible damage, contamination, loose components, and incorrect specifications.

Confirm that the valve size, materials, pressure rating, connection type, and operating direction match the approved piping design.

Clean and flush the pipeline to remove:

• Dirt

• Sand

• Metal particles

• Welding debris

• Pipe shavings

• Scale

• Other foreign materials

Position the valve carefully between the connected piping components. The disc must have enough clearance to rotate without striking the pipe or flange interior.

Align the piping properly before tightening the bolts. The valve should not be used to pull severely misaligned piping into position.

Tighten bolts gradually and evenly using a cross-tightening sequence. Excessive or uneven tightening may damage the valve body, seat, flange, or connected piping.

The pipeline should be properly supported so that pipe weight and mechanical stress are not transferred to the valve.

After installation, operate the valve slowly through its full range to confirm that the disc moves freely.

Follow the manufacturer’s installation instructions and the approved project procedure.

Installation and testing should be performed by qualified personnel.

Operate valves periodically when permitted by the system procedure to help confirm that the disc and operator remain functional.

Before removing or servicing the valve, isolate the pipeline, release the pressure, drain the fluid, and confirm that the system is safe.

Repairs and replacement should be performed by qualified personnel using compatible components.
