Butterfly Valves Exporter


Low Cost / Quick Operation / Light & Compact : Zara Valves Pvt Ltd 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.

Benefits at a glance :-
  • Actuator flange accommodates all types of actuators
  • Stem bushing reduces torque and isolates the stem from the valve body, preventing seizure
  • Smooth finished disc flats to give a highly efficient seal
  • Precision profile disc provides bubble-tight shut-off and ensures minimum torque and longer seat life
  • Qualified for both gaseous and liquid service
  • Positive shutoff bi-directionally
  • Ease of maintenance
  • Short face-to-face dimension
