Introduction:
The series slurry knife gate valve is a bi-directional wafer knife gate valve equipped with two metal reinforced rubber sleeves, designed for applications with abrasive slurry.
Features:
1. Body：
a) Full port design minimizes pressure drop and maximizes flow capacity.
b) Port at body bottom allows media to be discharged, avoid media accumulation at lower body.
2. Gate：
a) Rectangular gate is machined to a sharp edge for big shear stress without damaging seats.
b) Gate surface is well polished at both sides for tight seal and less jamming.
c) Gate is hard chrome coated for metal sealing valve.
3. Seat：
a) Two seats, metal reinforced rubber sleeves can handle flow in both directions.
b) The rubber sleeves are replaceable with easy installation.
c) When gate is at open position, the seats compress each other tightly to achieve bubble tight
seal and protect valve inner cavity from flushing. Consequently, gate can be changed without
shutting down pipeline.
4. Other：
a) Double thrust bearing minimize the operating torque.
