WBLM
1、 Product Overview
The WBLM butterfly valve is a flange type metal hard seal butterfly valve, designed with a single or double eccentric structure, suitable for harsh working conditions such as high temperature, high pressure, and corrosive media. It has the characteristics of reliable sealing and wear resistance.
2、 Key parameters
Structure type
Flange connection: The valve body and pipeline are connected by flanges, and the sealing surface is welded with stainless steel or hard alloy, which has strong erosion resistance.
Drive mode: Supports manual (worm gear), electric, pneumatic or hydraulic drive.
Technical specifications
Nominal diameter: DN50~DN2000 (some models can reach DN4000).
Pressure rating: PN10~PN25 (some models support PN40).
Applicable temperature: -29 ℃~600 ℃ (depending on valve body material and sealing material).
Sealing performance
Metal hard seal design, leakage level in accordance with ISO 5208 standard, balanced bi-directional pressure bearing capacity.
3、 Application scenarios
Typical industries: high demand fields such as petrochemicals, power, metallurgy, etc., especially suitable for steam, gas, and particulate media.
Advantages:
Single eccentric structure reduces friction and extends service life;
The replaceable valve seat design reduces maintenance costs.
