TTV Lugged Butterfly Valve - Food Grade Silicone Seat
TTV Lugged Butterfly Valve - Food Grade Silicone Seat
Couldn't load pickup availability
The Lugged Pattern TTV Butterfly Valve is a high-quality valve designed for reliable and efficient flow control in various industrial applications. Engineered with precision, this valve is constructed from durable Ductile Iron GJS500-7, ensuring superior strength, longevity, and resistance to wear and tear.
Rated at PN16, this valve is suitable for medium pressure applications, offering optimal performance in systems requiring robust and secure sealing. The silicone seat provides excellent chemical resistance and high-temperature tolerance, ensuring a tight seal and minimizing the risk of leakage, even in demanding conditions.
The valve is equipped with a lockable lever mechanism, allowing for easy manual operation while providing the option to secure the valve in the desired position. This feature is particularly useful in applications where safety and controlled operation are critical.
The lugged design facilitates easy installation and maintenance, allowing the valve to be removed from the pipeline without disturbing the surrounding connections. This makes it an ideal choice for systems where maintenance downtime needs to be minimised.

FAQ's
What is the difference between a valve and an actuator?
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.
