⚠️ Now Fully WRAS Approved – Valve & EPDM Seat

TTV Aluminium Bronze Lugged Butterfly Valves with EPDM Seat

The TTV Aluminium Bronze Lugged Butterfly Valves are now fully WRAS approved, covering both the EPDM seat and the complete valve assembly. Engineered for challenging environments, these valves feature a full aluminium bronze body and disc for superior corrosion resistance — especially in saline or mildly aggressive media — while now offering certified compliance for potable water systems.

Designed with a lugged body pattern, this valve supports secure flange mounting and end-of-line service without disrupting the entire pipeline. Combined with a bubble-tight EPDM seal, low torque operation, and ISO 5211 mounting, it’s a robust and versatile choice for marine, water distribution, and industrial flow control setups.

Key Features:

- WRAS Approved Valve & EPDM Seat – Fully certified for potable water contact
- Aluminium Bronze Body & Disc – Exceptional corrosion resistance in harsh environments
- Lugged Pattern Design – Suitable for dead-end service and rigid flange connection
- Bubble-Tight Shut-Off – Delivers reliable leak-free sealing under pressure
- ISO 5211 Mounting Pad – Ready for direct actuator mounting
- Low Operating Torque – Smooth manual or automated operation
- Replaceable Seat Design – Easy maintenance and extended service life

A corrosion-resistant, WRAS-certified butterfly valve built to perform where both material reliability and water safety compliance are essential.

FAQ's

What is the difference between a valve and an actuator?

A valve controls the flow of a fluid (such as water, gas, or steam), while an actuator is the device that operates the valve — automatically opening, closing, or positioning it. Actuators can be electric, pneumatic, or hydraulic, depending on the application and control requirements.

What types of actuators are available?

The main types of actuators are:

Pneumatic actuators – use compressed air for fast, reliable operation.

Electric actuators – use electrical power for precise control.

Hydraulic actuators – use fluid pressure for high-torque applications.

Each type offers unique advantages depending on the environment, media, and system control needs.

How do I choose the right actuator for my valve?

To select the correct actuator, consider:

Valve type and torque requirement

Power source available (air, electric, or hydraulic)

Operating environment (temperature, humidity, hazardous area)

Control signal type (on/off or modulating)

Matching actuator torque and compatibility with the valve’s ISO mounting ensures reliable performance.

What are the main types of valves used in automation?

The most common valves in automated systems include:

Ball valves – for tight shutoff and quick operation.

Butterfly valves – for larger flow control with compact design.

Globe valves – for precise throttling and flow regulation.

Check valves – to prevent backflow.

Gate valves – for full bore flow isolation.

What’s the difference between a double-acting and spring-return actuator?

Double-acting actuators use air (or power) to both open and close the valve.


Spring-return actuators use air to open (or close) the valve, and a built-in spring to automatically return it to a safe position when power or air is lost — ideal for fail-safe operation.

How often should valves and actuators be serviced?

Regular maintenance intervals depend on operating conditions, but a good rule of thumb is to inspect every 6–12 months.

This includes checking for leaks, lubrication, seal wear, and actuator responsiveness to prevent unexpected downtime.
