Frequently Asked Questions

What is the difference between concentric and eccentric Interapp butterfly valves? ▾
Concentric butterfly valves have the disc shaft centered and are suitable for low pressures up to 10 bar. Double-eccentric butterfly valves have an offset disc that does not contact the seal on closing, making them suitable for higher pressures up to 40 bar with longer seal life.
Are Interapp butterfly valves suitable for drinking water? ▾
Yes, Interapp supplies butterfly valves with drinking water approval (WRAS, KTW, ACS) for use in drinking water installations. The seat ring and body are manufactured from approved materials that do not release harmful substances into the drinking water.
Which actuator do I choose for Interapp butterfly valve automation? ▾
Choose an actuator based on the required torque (determined by valve size and working pressure), the available control medium (compressed air or electricity), and the required fail position (fail-open or fail-closed). Our specialists calculate the minimum actuator torque for your valve.
Are Interapp valves suitable for the food industry? ▾
Yes, Interapp supplies hygienic valves conforming to EHEDG and 3A standards for the food and pharmaceutical industries. These models feature smooth internal surfaces, hygienic seals, and are fully cleanable in CIP systems.
How do I order an Interapp butterfly valve? ▾
When ordering, specify the nominal diameter (DN), pressure class (PN), pipe material (for correct flange size), the medium, and the desired material choice (cast iron, SS, PVDF). Our specialists assemble the correct product configuration.
