Product Details
Description:

A brief introduction:
SPZ673 series Double drive pneumatic knife gate valve Slurry and flashboard valve is one of the automatic control valve in the production process of varieties. A straight stroke piston type pneumatic actuator and knife type valve structure, equipped with a solenoid valve through the completion of the two cut off control, equipped with electric valve positioner can also complete control. The user can choose according to the actual needs. The main use of cast steel, stainless steel and other materials. Especially suitable for papermaking industry, chemical industry, coal, water, sugar and other industries to make adjustments or cut off the fluid control in the pipeline.
Second, SPZ673 Double drive pneumatic knife gate valve Characteristic:
1. knife gate slurry, dark rod and rod of both single and double seal structure; sealing structure, full circle design of the DC channel without slag, block. Processed into the bottom plate blade knife blade, a sealing ring with plane floating, floating ball arc metal sealing structure, between the gate and the metal seat is gapless hoist, on soft materials such as fiber, pulp, wood pulp with large shearing force and self-cleaning function, but also has good opening and closing function. The upper blades installed in the hard Teflon wiper can prevent dust and scratch gravel and other substances into the packing box, can significantly increase the life of blades.
2. body, filling culvert are precision casting, the whole body with flange type casting, valve plate made of stainless steel and precision processing can obtain ideal sealing effect of grinding and polishing. Compact design, small occupying space, light weight, easy installation, wear-resistant, non stick slag anti blocking measures to perfect and convenient maintenance and long service life.
3., slurry knife gate valve can be made within the V shape, U shape, triangle channel. V type gate control can be used as a regulator, the connection form of clip, flange lug, metal to metal seal, metal sealing of soft polyurethane, PTFE seal.
The 4. piston pneumatic actuator, powered by compressed air, an air pressure signal of electric - gas valve positioner or solenoid valve input, the pressure thrust on the piston, and the push rod displacement, to achieve linear motion.
5. medium: gold powder, tailings, pulp, wood pulp, fiber, dust, chemicals, sewage treatment tank, ore, slag, coal, asphalt, outlet, fruit, grain, cement slurry, slaughter wastewater etc..
