Dharmi Engineers Wafer Type Butterfly Valve have been developed with extensive application, design and manufacturing expertise. Dharmi Engineers High Performance Slim-Seal, Concentric design Butterfly Valves are reliable, maintenance free shutoff with permanently gas-tight seal with an integrally moulded or replaceable elastomer body liner. Dharmi Engineers Butterfly 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. Dharmi Engineers High performance butterfly valves are also available with Full-Lugs type body with raised faces and flanged ends connection on request.
Dharmi Engineers Butterfly Valve, Wafer Type, Slim-Seal design, maintenance free shutoff. This 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.
Dharmi Engineers Slim Seal 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. The slim-seal, center disc design valves are widely available with different combination of body, seat & disc materials to satisfy the need of most industrial application. |

Body Test |
|
1.5 times the working pressure with water. This test is performed after valve assembly and with disc in half position open, it is called as a body hydro test. |
|
Seat Test |
|
1.5 times the working pressure with water. |
|
Function / Operation Test |
|
At the time of final inspection, each valve and its actuator (Flow-Control Lever / Gear / Pneumatic Actuator), under goes a complete operating test (Open/Close). This test carried out without pressure and at ambient temperature. It ensures the correct operation of the valve / actuator assembly with accessories such as solenoid valve, limit switches, air filter regulator etc. |

Special Test |
|
On request, any other test can be carried out according to special instruction by client | |
