Abrasion Resient Slurry Dedicated Wafer Type Butterfly Valve Manufacturer, Rubber Lined Wear Resistant
Core Advantages of Rubber Lined Wear Resistant Wafer Type Butterfly Valve
The interior of the valve body and the surface of the disc of the abrasion resistant slurry dedicated wafer type butterfly valve are lined with high-elasticity natural rubber or wear resistant polyurethane. This rubber lining layer has the following notable characteristics: High wear resistance – capable of long-term withstanding severe erosion from solid-containing media such as ore sand, tailings, and coal slurry; Tear resistance – the elastic rubber lining absorbs particle impact energy, reducing damage to the metal valve body; Corrosion resistance – resistant to weak acids, weak alkalis, and chemical agents in slurry. The rubber lining layer completely isolates the metal components from the abrasive medium, greatly extending the service life of the valve.
Comparison of Wear Resistant Rubber Lining MaterialsThe main Butterfly Valve product names of China Butterfly Valve Network include:Three Eccentric Multi-level Metal Hard-sealed Wafer Butterfly Valve,High Temperature Butterfly Valve,Electric Desulfurization Flange Butterfly Valve,Flange Ceramic Hard-sealed Butterfly Valve,Pneumatic High Vacuum Butterfly Valve,Fire Signal Butterfly Valve,Quick-installed Sanitary Butterfly Valve,Worm Gear Metal Hard-sealed Wafer Butterfly Valve.
Different types of rubber lining are suitable for different slurry working conditions: Natural hard rubber – high hardness, excellent wear resistance, suitable for slurry containing coarse particles; Butyl rubber – acid and alkali resistant, aging resistant, suitable for chemical tailings; Polyurethane elastomer – wear resistance 3-5 times that of natural rubber, suitable for high-velocity, high-concentration slurry; EPDM – suitable for oily slurry and certain temperature conditions.
Factory Direct Price Range
Currently, the factory direct prices for wear resistant rubber lined wafer type butterfly valves generally range as follows: DN50 size approximately RMB 320-550, DN80 size approximately RMB 420-750, DN100 size approximately RMB 550-950, DN150 size approximately RMB 850-1,450, DN200 size approximately RMB 1,250-2,100. The specific price is influenced by valve body material (cast iron/ductile iron/cast steel), rubber lining material and thickness, disc material (ordinary galvanized plate/stainless steel), and actuation method (manual worm gear/pneumatic/electric).
Purchasing Suggestions
It is recommended that users provide parameters such as slurry concentration, particle size and hardness, medium temperature, and flow velocity before procurement. Request rubber lining layer hardness test reports and pinhole spark test reports from suppliers. Give priority to factory direct products that comply with GB/T 12238 and HG/T 20592 standards, and request quotes from at least three professional rubber lined valve manufacturers for comparison.
