⚠️ Now Fully WRAS Approved – Valve & EPDM Seat

TTV Ductile Iron Lugged Butterfly Valves with EPDM Seat

The TTV Ductile Iron Lugged Butterfly Valves are now fully WRAS approved, meaning both the EPDM seat and the complete valve assembly are certified for use with potable water systems. Designed for durability and reliability, these valves are ideal for water, HVAC, and general industrial applications that require strong, long-lasting components with certified water safety compliance.

Built from robust ductile iron and equipped with a resilient EPDM seat, these valves deliver bubble-tight shut-off and smooth, low-torque operation. The lugged body pattern allows for secure flange-to-flange mounting and dead-end service, making them a practical choice for isolated sections or end-of-line installations.

Key Features:

- WRAS Approved Valve & EPDM Seat – Fully certified for potable water use
- Ductile Iron Body – Strong and pressure-resistant, suitable for demanding applications
- Lugged Pattern Design – Allows for secure bolting and dead-end service
- Bubble-Tight Shut-Off – Ensures dependable sealing performance
- ISO 5211 Mounting Pad – Easy integration with actuators
- Low Torque Operation – Smooth control for manual or automated use
- Maintenance-Friendly Design – Replaceable internal components for extended life

A reliable, fully WRAS-approved solution for potable water systems and industrial flow control — combining certified safety, strength, and serviceability in one rugged package.

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.
