Butterfly Valves | Crane Engineering

Selecting the right butterfly valve depends on your system’s pressure, temperature, media, and environment. Consider the following:

Fluid type – Is the fluid clean, corrosive, or contains particulates?
Pressure rating – Ensure the valve’s pressure class matches system requirements.
Temperature range – Choose materials that can withstand your process temperature.
Actuation – Manual, pneumatic, or electric actuation based on your automation needs.
End connection – Wafer or lug configuration depending on the piping system.

Crane Engineering’s valve specialists can help you specify the correct valve for your process, ensuring long-term reliability and performance

Types of Butterfly Valves

Each type of butterfly valve is designed to meet specific operating conditions and performance requirements:

Wafer-Style Butterfly Valves – Compact and lightweight, ideal for low-pressure applications.
Lug-Style Butterfly Valves – Provide easy removal and maintenance without disrupting pipeline sections.
Double-Offset (High-Performance) Butterfly Valves – Offer tighter shut-off and longer service life for higher pressure and temperature ranges.
Triple-Offset Butterfly Valves – Designed for severe service applications where absolute zero leakage and durability are essential.

What size butterfly valves do you offer?

We stock valves ranging from 2” to 48” with pressure ratings suitable for a wide range of flow applications.

Can butterfly valves be automated?

Yes. We offer both pneumatic and electric actuators for automated operation and remote control.

What’s the difference between wafer and lug style valves?

Wafer valves fit between flanges and are secured with bolts, while lug valves have threaded inserts for independent flange bolting.

Are butterfly valves suitable for high-temperature applications?

Yes, when constructed with high-performance materials such as stainless steel bodies and PTFE seats.
