Couldn't load pickup availability
The Wafer Pattern TTV Butterfly Valve is a solid and reliable option for flow control in various applications. With a PN16 pressure rating, it's made from tough Ductile Iron GJS500-7, which means it's built to last and can handle the wear and tear of industrial use.
This valve comes with an EPDM seat, which is known for its excellent sealing capabilities. It's resistant to a wide range of chemicals, making it a good fit for systems involving water, oils, and some acids. Plus, it can handle high temperatures and pressures, so you won't have to worry about performance issues in demanding situations.
A key feature of this valve is the lockable lever. This makes it easy to operate manually while also allowing you to lock it in place for added security, which is crucial in environments where safety is a priority.
The wafer design of this valve means it's compact and straightforward to install between flanges, saving space and reducing the need for extra hardware. It’s designed to minimise pressure drop and ensure smooth flow control, making it a practical choice for systems that require regular operation.
Whether you’re dealing with water treatment, HVAC, or general industrial piping, the Wafer Pattern TTV Butterfly Valve is a dependable and cost-effective choice that’s built to perform under tough conditions.

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.
