Technical Specifications

Models and Options

Model GB/T 12237 (WCB) with pressure ratings: PN16, PN25, PN40. Seat material options: PTFE or EPDM. Actuation can be manual, electric, pneumatic, or hydraulic.

Materials and Structure

The valve features a WCB carbon steel body and disc, ensuring excellent resistance to abrasion and erosion. The knife gate design provides a sharp cutting edge for effective closure in particulate-laden media. PTFE and EPDM seats offer low friction and chemical inertness.

Applications

Commonly used in power plant ash handling systems, coal mining slurry pipelines, and industrial waste treatment. Ideal for media containing solid particles and requiring positive shut-off.

Customization

We can customize flange dimensions, face-to-face lengths, and actuator mounting per customer drawings. Additional surface treatments for enhanced corrosion resistance are available.

FAQ

Q1: What is the maximum working pressure?

The valve is rated up to PN40 (approximately 40 bar) depending on size and material selection.

Q2: Can it be used for corrosive chemicals?

It depends on the seat material and the specific chemical. PTFE offers excellent chemical resistance, but we recommend consulting for compatibility.

Q3: How do I select the right actuator?

Consider valve size, required torque, and available power source. Our engineers can assist in selection based on your system parameters.

Q4: Are these valves suitable for outdoor installation?

Yes, with appropriate weatherproofing for actuators, they can be installed outdoors.
