Zero Leakge, High Performance, Spherical Disc, Dual Eccentric Disc, Double Offset Disc Butterfly Valve have been developed with extensive application, design and manufacturing expertise. Zeel engineers make High Performance, Renewable PTFE Seat, Wafer Type – Flangeless Butterfly Valves are reliable, maintenance free shutoff with permanently gas-tight seal with an replaceable Teflon or Elastomer Rubber Seat.

Double Offset Disc Butterfly Valve wafer type body having two nos. flange locating holes for sizes up to 12” and from size 14” and above 04 nos. for easy alignment of valve during installation. Flange locating hole confirm to as per ANSI B 16.5 Class 125 & Class 150 / BS 10 Table “D”, “E”, “F” / PN 6, PN 10, PN 16 or other international standard.

We are also manufacturers and exporters of Double Flanged End Double Offset Disc Butterfly Valves with renewable type seat with Flow Control Lever, Gear, Pneumatic Actuator, Motorized Electrical Actuator Operated.

Spherical Disc Type butterfly valves excess other conventional valves such as gate valve and globe valves in all aspects, especially in terms of light weight, less number of component, no flange gaskets required and economical operation and maintenance costs.

Our manufacturing range of Double Eccentric Disc Design Butterfly Valves body seat mechanism have a very low torque, tight shut off with zero leakage, compact actuator selection, and long life smooth easy operation. High Performance type eccentric disc design valves are widely available with different combination of body, seat & disc materials to satisfy the need of most industrial application.

We manufacture and exporting zero leakge, dual eccentric disc butterfly valves with variety of elastomer rubber seat to suit various industrial application. Our seat range of elastomer covers EPDM, NBR, Buna-N, Nitirle, Silicon, Viton, Hypalon, PTFE. Our Size range of Butterfly Valve cover up to 24″ (DN600/600NB/600MM) Size.

Zeel engineers also manufacturing butterfly valves in special grade of material like CN7M-Alloy20, Nickel Aluminium Bronze, NAB2, Hastelloy C22/276, Monel, SS304L, SS 316L, SS317L, D2205, D2507, 4A, 5A & Super Duplex Steel for Sea Water & Corrosive application.
