Grooved end butterfly valves are fixed to the pipes by means of standard clamping couplings. The grooved end clamping system is widely used for indoor fire protection installations since it is a fast and efficient way of joining pipes due to its high degree of flexibility. Furthermore, it absorbs vibrations and noise transmission through the system.
Grooved end butterfly valve: Ductile Cast Iron
Wafer butterfly valve: Grey Cast Iron; Ductile Cast Iron, Stainless Steel 304/316; Carbon Steel.
CLASS 125/150; PN10/16/25; 5K/10K/16K.
Both of them are designed for water and air applications
Wafer butterfly valves are slightly more economical, but grooved butterfly valves and couplings install quickly and offer several other benefits.
A Grooved butterfly valve regulates flow by starting, slowing, or stopping media. The disk opens and closes with a low-torque rotation of 90 degrees and works for any compatible application. Because they cost less and are lighter weight, the Grooved butterfly valve is often preferred over other types of valves.
In comparison to other valve types, Grooved butterfly valves are relatively lightweight, especially at larger sizes. Because they embody a simple and economical design, they have fewer parts, which makes them easier to repair and maintain. Furthermore, their straightforward design reduces the time required to install one, decreasing labor costs.
