Product Details

Application

PZ41H, PZ41TC gate valve is designed for slurry pipeline of hydraulic ash handling system in thermal power plant. It is used to shut off ash & water flow when required.

Working condition

Pressure: 1.6～6.4MPa
Temperature: 0～100℃

Medium

Slurry of ash handling system, namely mixture of ash & water. Ash to water ratio should be less than ≤1:15. Max size of particles should be less than 50mm.

Material

Body & bonnet: WCB
Disc: WCB+D577
Seat: WCB+D516MA
Stem: 2Cr13
Packing: expanded graphite

Features

Valve disc in wedge shape.
Tight closure. Groove at the bottom of valve body designed to expel deposits inside.
Packing material with special sealing to prevent ingress of particles.
Wearing & corrosion resistant valve stem treated by thermal refining and nitriding process.
Sealing surface made of alloy steel. Excellent resistance to erosion and wear.
Smooth flow pass. No accumulation of ash, no jamming, flexible operation.
Ceramic lining on request.
Manual & actuator operation.
