Butterfly valve Lining

Nominal Diameter, DN: 50…2000 mm

Nominal Pressure, PN: 6/10/16 bar (PN25 on request)

Leakage rate: А, according to DIN EN 12266

Centric valves with centric design are widespread due to their relatively low cost and simplicity of design.

Butterfly valves can be used whether as a shutoff fitting, so as a control valve. Rubber lined butterfly valves have a large range of applications.

The targeted mediums for these valves are liquids and gases with temperature up to 150 °C.

Due to the fact that the medium in this valve type does not contact with the fitting body, valves with cast iron body may be used in such fluids like water, seawater, aсids, alkalis, petroleum products, natural gas…

Butterfly valves have the following advantages: low cost, reliability, small dimensions and low weight of valve.

Depends on medium type and operational conditions our engineers will help you select the right seal material. Seal applicable in this range:

  • EPDM
  • NBR
  • FMP (Viton)
  • Silicone

Valves of omarain have lining bonded to the body provided increased service life and two-wayleakage rate class A. Valves with such seal work also reliably in vacuum systems.

As the body material we use a cast iron, ductile cast iron, steel, stainless steel. On demand we can manufacture these valve bodies of bronze.

Omarain can offer you various designs of butterfly valves:

  • Wafer type
  • Lug type
  • Single Flange Wafer Type
  • Flange U-Section Type
  • Double flange

We can offer you pneumatic single- and double-acting actuators with various additional equipment such as: positioner, solenoid valve, limit switches or electric actuator, also we can offer you lever and manual override operated butterfly valves.
