BUTTERFLY VALVES
 
 
Low Cost / Quick Operation / Light & Compact : offers a complete line of resilient seated Butterfly Valves. ZARA’s "ZIV" brand rugged and reliable valves are built to last.

The body liner which also functions as the soft seat, comes in either a replaceable version or an integrally moulded version and offers 100% bi-directional sealing against vaccum to rated pressure of PN10 or PN16. 

One unique feature is the international compability of our valves with most world flange standards hence one valve design can be used in many markets worldwide.
