Technical Specifications

Models and Options

Models include DIN 19526 (WCB) with pressure ratings PN16, PN25, and PN40. Seat options: PTFE or EPDM. Actuation can be manual or automated with electric, pneumatic, or hydraulic actuators.

Materials and Structure

Constructed with WCB carbon steel for the body and disc, ensuring robust performance in abrasive environments. The knife gate design effectively shears through slurries and viscous fluids. PTFE or EPDM seats provide chemical resistance and low friction.

Applications

Ideal for mining industry, power plant ash handling, and industrial waste slurry. Also used in mining water supply systems where abrasion resistance is critical.

Customization

Customizable options include flange standards (DIN, ANSI), actuator types, and special coatings for enhanced corrosion resistance. Contact us for tailored solutions.

FAQ

Q1: Can this valve handle high-temperature fluids?

The maximum temperature is limited by the seat material: PTFE up to 180°C, EPDM up to 120°C. For higher temperatures, consider alternative seat materials or special construction.

Q2: Is the valve suitable for underground mining installations?

Yes, the robust design and materials make it suitable for underground mining water supply systems. It can withstand harsh conditions.

Q3: What is the delivery time?

Standard production time is 30-45 days, but it may vary based on order quantity and custom requirements.
