DN125 mining MA explosion-proof electric soft seal disc valve

1DN125 mining MA explosion-proof electric soft seal disc valveStructure and Composition

valve body

Usually made of cast iron, carbon steel or stainless steel, lined with fluoroplastic (such asPTFE, FEP, PFA, etc. ensure that all parts in contact with corrosive media are covered with fluoroplastics.

Clamp design: directly clamped between pipeline flanges with bolts, compact structure, and light weight.

Valve plate (butterfly plate)

The material is stainless steel or fluorine lined, and the surface is coated with fluoroplastic or rubber to ensure corrosion resistance and sealing. Mostly eccentric structures (such as double eccentricity or triple eccentricity) reduce friction and extend lifespan.

Valve seat (sealing ring)

Soft sealing materials: commonly usedEPDM, NBR, PTFE, etc. are corrosion-resistant and have excellent sealing performance (up to zero leakage). Some designs use elastic valve seats to compensate for deformation caused by temperature or pressure changes.

valve stem

Stainless steel material (such as304, 316), partially coated or fluorine lined to prevent medium corrosion.

Drive Type

Manual (handle, worm gear), pneumatic, electric, etc., choose according to the requirements of the working conditions.

IIDN125 mining MA explosion-proof electric soft seal disc valveCore Features

corrosion resistance

The lining fluoroplastic can withstand most corrosive media such as strong acids (sulfuric acid, hydrochloric acid), strong alkalis, organic solvents, etc.

Excellent sealing performance

Soft sealed valve seats can also achieve bubble level sealing under low pressure (such asANSI Class VI standard).

Lightweight and energy-efficient

Low resistance to fluid, low opening and closing torque, and effortless operation.

Wide temperature and pressure range

General applicable temperature:-20 ℃~150 ℃ (depending on the fluorine lining material); Pressure range: PN6~PN16.

Long lifespan and low maintenance

The chemical inertness of fluoroplastics reduces scaling and wear, making them suitable for long-term use.

Medium characteristics: Confirm corrosive components, concentration, and temperature.

Pressure level: selected based on system pressurePN6/10/16, etc.

Sealing material:

EPDM: resistant to weak acid and alkali, hot water;

PTFE: resistant to strong corrosion and high temperature.

Connection standard:ANSI, DIN, GB and other flange specifications.

Drive mode: It is recommended to choose pneumatic for frequent opening and closing/Electric.

5、 Installation and maintenance

Installation:

For clamp type valves, it is necessary to ensure that the pipeline flanges are aligned and the bolts are evenly tightened to avoid deformation of the valve body.

Remove impurities from the pipeline before installation to prevent damage to the sealing surface.

maintain:

Regularly check the sealing of the valve seat and clean the accumulated dirt on the valve plate.

Avoid using under high temperature and pressure to prevent the aging of the fluoroplastic layer.
