ARP - Model CS-L10 Series -Butterfly Damper Valve
FromARP Industry srl
All butterfly valve series are characterized by a circular cross section with concentric single or double blade. The double blade valve is the better choice for modulating service. Our butterfly valves can be designed as standard or heavy duty construction.
Standard fabrication is the optimal design in most applications. Heavy duty design is suitable for frequent service, highly corrosive applications, abrasive media and high temperature environments.
