Pneumatic Wafer Knife Gate Valve Ductile Iron Body SS304 Knife Plate With Solenoid Valve for Slurry Sewage Powder Pipeline
Adopts lug wafer connection design, compact structure and light weight, which greatly saves pipeline installation space. It can be quickly clamped between two pipeline flanges without complicated bolt layout, effectively shortening on-site construction time and installation cost.
Straight-through full bore flow channel avoids material accumulation, effectively preventing jamming caused by sludge, fiber, dust and solid particles. It is the ideal shut-off valve for sewage, slurry, grain powder and other easy-blocking working conditions.
Equipped with pneumatic actuator, air filter regulator, solenoid valve and limit switch. It can connect to PLC control system to realize remote automatic switch, and feed back valve opening and closing status in real time to ensure safe pipeline operation.
The valve body is made of anti-corrosion ductile iron with SS304 stainless steel blade. Soft rubber, PTFE and metal hard seals are optional, suitable for normal temperature, wear-resistant and slightly corrosive industrial medium conveying pipelines.
Complete size range from DN50 to DN300, PN10/PN16 pressure standard. We support OEM customization such as explosion-proof electrical parts, full stainless steel valve body and special sealing materials to meet different industrial project requirements.
