ISO 5211 ACTUATOR ASSEMBLY
ZPR810F Series Lined Regulated Butterfly Valve consists of a pneumatic piston actuator and a PTFE-sealed butterfly valve,suitable for corrosive-demanding working conditions with temperatures ≤160°℃.The valve adopts thick polymerlining technology on allfluid-contact components(valve body,disc,and stem),demonstrating excellent corrosion resistance and compatibility with any concentration of acids,alkalis,salts,oxidizers,reducing agents,and organicsolvents
As an ideal product for shut-off and regulation in pipelines and containers handling gases,liquids,and semi-fluids,it is widely used in chemical,petroleum,pharmaceutical,food,steel smelting,paper-making,and hydro-power systems.The fully lined PTFE(F4)and FEP(F46)butterfly valve offers superior corrosion resistance,zero leakage,and extended service life.
This corrosion-resistant butterfly valve is particularly suitable for concentrated sulfuric acid,hydrochloric acid,nitric acid,hydrofluoric acid,aqua regia,various organc acids and other highly corrosive media.
| Features | Description |
| Superior Corrosion Resistance |
Independent seat assembly +fully lined flow path eliminates metallic corrosion exposure |
| Exclusive Material | Due to PTFE’s non-flow characteristics,the butterfly valve is the only valve type capable of being produced with PTFE material |
| Structural Uniqueness | Split valve body design,the shaft seals is achieved through a rotating fluororubber-incorporated interface between the disc and seat |
| Customizable Disc | PTFE disc and shaft adopt square shaft insertion design,while FEP and PFA utilize flat shaft welded structure |
| Reliable Sealing Performance |
Fully-lined disc and silicone gasket under the valve seat ensures reliable tight sealing performance |
| Diverse Options | Selection based on working conditions:Fully-lined butterfly valves and semi-lined butterfly valves are available |
| Standard Mounting Platform |
One-piece body/bracket ensures stable operation with ISO 5211-compliant actuator mounting. |
ADVANTAGES:
1. Excellent resistance to chemical corrosion, low friction and operate in a wide range of temperatures.
2. Small size and light weight, easy to install and maintenance
3. Excellent sealing performance with non-leak provides long service life.
4.Simple structure and can be quickly Open or shut-off by 90 degrees rotation.
5.Pneumatic and electric actuators can be configured according to customer requirements to meet the needs of remote control.
