Product details

Double eccentricbutterfly valve Product description

Flange butterfly valve, mounting between flanges PN10/PN16/A150, with gear box.

The range of WESDOM valves can be used for overground installation, in valve chambers and buried systems.butterfly valves in a range of DN 150 to 2000 mm and PN 10, 16 and 25 bar have been designed to isolate the flow of fluid in:

  • potable water supply pipelines and treatment plants.
  • transportation of filtered and recycled water.
  • irrigation distribution networks.
  • water-pumping stations and hydroelectric plants.
  •   reservoirs.

The range of WESDOM valves can be used for overground installation, in valve chambers and buried systems. It includes a full range of operating accessories and actuators.

WESDOM valves are installed all over the Asia,Africa continent, the Middle East and throughout Europe. They have justifiably acquired a faultless reputation for their durability, reliability and quality worldwide.

Features

Double eccentric butterfly valve Standard:

Design and Manufacture Conform to EN 593, API609,  JIS

Flange dimensions Conform to EN 1092-2 PN10, PN16, JIS5K, JIS10K,ANSI B16.1,DIN2501,BS4504

Face to Face dimensions Conform to EN558 series

Top Flange dimensions Conform to ISO5211

Testing Conform to API598、EN12266-1

 

Double eccentric butterfly valve features:

1.Protection of gearbox IP 68-8 (submersion up to 8 m of water) and actuator IP 68 (submersion up to 8 m of water, during 96 hours and 10operations)

  • With position indicator.
  • Clockwise Close (CC).
  • For installation above ground and in non-flooded chambers.
  • Designed and tested to an endurance level of 2500 cycles minimum, inaccordance with EN 1074-1 and 2.

 

2.Reduces resilient seal’s wear and tear ensuring detachment from the body seat ring the moment the valve begins to open.

  • reduces pressure loss in fully open position by the disc

parking in a zone of reduced flow.

  • lower torque requirement to rotate the disc leads to less

wear and longer life of the gasket and other elements.

 

Double eccentric butterfly valve Application:

  • potable water supply pipelines and treatment plants.
  • transportation of filtered and recycled water.
  • irrigation distribution networks.
  • water-pumping stations and hydroelectric plants.
  • nuclear industry, fire safety and storage facilities.

Standard

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:  1.1 times the working pressure with water.

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