RAQ

What is a grovved butterfly valve? +

A grooved butterfly valve is a quarter-turn shutoff valve designed for grooved piping systems. It connects to pipes through grooved-end couplings instead of flanged or threaded connections, enabling faster installation, easier maintenance, and reliable sealing. It is widely used in fire protection, HVAC, water supply, and industrial piping systems.

What materials are available for grooved end butterfly valves? +

Grooved butterfly valves are available in ductile iron or stainless steel bodies with discs in ductile iron, stainless steel 304, stainless steel 316, or aluminum bronze. Seat materials include EPDM, NBR, providing reliable performance for water, HVAC, fire protection, and various industrial applications.

What are the advantages of a grooved butterfly valve? +

A grooved butterfly valve offers fast installation, easy maintenance, and reliable sealing. Its grooved-end connection reduces labor time and eliminates welding, making it ideal for fire protection, HVAC, water treatment, and industrial piping systems. The compact design, low operating torque, and long service life help reduce overall operating and maintenance costs.

Which industries is it suitable for? +

Fire protection, HVAC, water treatment, municipal water supply and industrial piping systems.

Can it be supplied with actuators? +

Yes. Manual, gear, pneumatic and electric actuators are available.
